5 Accessories

The following chapter provides information about how to choose the right accessories and howto use them properly.

SafetyDetection devices that do not work correctly can provide no protection and can lead to accidents. The only way to guaranty a reliable and correct measurement and warning of gasrisks is to test your detection device using a known gas concentration. This is commonly referred to as a function or bump test. The device may need to be calibrated.

Additional featuresYou can extend the functionality of gas detection devices by using the right accessories. Forinstance, a device for personal monitoring can be turned into a device for detecting leaks and for performing clearance measurements when entering confined spaces, simply by using a pump, probe, and extension hose. The right materials are important – for example, when using extension hoses.

Configuration/documentation/archivingGas detection devices can be adapted to a variety of applications by adjusting them to different evaluation parameters using an additional software program. This software runs ona separate computer. In many places of work, the exposure to hazardous material must be evaluated and documented. This process should be quick and intuitive.

Gas detection devices are used for continuous measurements. Environmental influences orother gases can change the calibration, with which the sensor is delivered to the customer.Testing an instrument using a known gas concentration (also known as a function or bumptest) is the only way to guarantee reliable and correct measurement of and warning againstgas hazards. This test is important to verify whether the gas to be measured can flow throughthe dust and water filter to the sensor, to check that the sensor is properly calibrated, and totest that alarms are working and are set correctly. If the gas detector has been in contact withvery high concentrations of toxic gases or vapours, it must immediately undergo a function(bump) test and the necessary adjustments, regardless of the required function test interval.

The various institutions stipulate regular sensitivity checks and functional tests (bump tests)for gas detection devices; In Germany, BG Chemie therefore recommends regular checks /calibrations in its data sheets T021 (gas warning equipment for toxic gases/vapors) / T023(gas warning equipment for explosion protection). The EN 60079-29-2 standard (Gas detection devices – selection, installation, application, and maintenance of equipment for

5.2 Equipment for calibration and function tests

the measurement of flammable gases and oxygen), which applies to all the member statesof the European Union also stipulates a sensitivity test immediately before use (international: IEC 60079-29-2).

The easiest and least expensive way to test the function of your portable gas detection instrument is to conduct a basic test with gas.All you need is a test gas bottle containing the respective test gas, atrigger regulator and aninstrument-specific calibration adapter. Theinstrument's alarm is triggered by briefly exposing the sensors to thetest gas. To adjust the instrument via a PC, you need additionally theDräger CC-Vision software, which allows individual configuration andcalibration of your gas detection instruments.

The Dräger Bump Test Station was designed to allow a function (bump) test to be performed with a test gas in order to check the warning functions of gas detection instruments. An integrated instrument-specific adapter is provided to test the Dräger Pac3500 to 7000, and of Dräger X-am 1/2/5500 5600/, 3000 and 7000. When the concen-tration shown on the instrument's display is within an acceptable tolerance to the concentra-tion of the test gas and the alarms were trigged, the function (bump) test was successful and verifies the instrument calibration. If the function (bump) test was not successful, the instrument needs to be calibrated. With some devices, this is done automatically following anunsuccessful function test in the Dräger Bump Test Station. Instruments with an event or datalogger will store the results (pass or fail) of the function (bump) test, as well as the subsequent automatic calibration when applicable. The Dräger Bump Test Station functionsindependently, without any external power supply, making it ideal for use anywhere in thefield. The data from the Dräger Bump Test Station can be sent to a Dräger mobile printer

5.4 Dräger Bump Test Station

using an optical port. This printer stores the results of the function testand prints them out. The results can also be exported using the Dräger CC-Vision software. The tests are very short – sometimes only ten seconds, because thesensors respond so quickly – which makes for very low gas consumption and reduced operating costs.

The Dräger E-Cal automatic testing and calibrating station incorporates as many as ten different instrument modules. Because Dräger detection devices can be calibrated and adjusted simultaneously, they are quick and therefore economic to maintain. The Dräger E-Cal is modular in design and, when fully equipped, can consist of a computer, a master station, and as many as ten different device modules.

Master stationThe Master Station allows you to use either two, six or twelve different gases, and supportsup to ten instrument modules.

Device moduleWhen a Dräger portable gas detection instrument is inserted into its module, the sensors contained within are automatically detected. Once calibration has been successfully completed, the results are shown on both the module and the PC. Additionally, you can usethe instrument module, with the respective plug, to charge your equipment. With the help ofan optional adapter and a computer, each device module can also be operated independently of the master station, and used as an economic alternative for simple testingof a device’s functionality.

Dräger CC-Vision softwareThe Dräger CC-Vision E-Cal software features intuitive operation and the configurable GO button makes the instrument even easier to use. Specific workshop processes i.e. function(bump) test, calibration, download of data logger or battery test are carried out automaticallyand simultaneously for up to 10 instruments. Combined with a search function, the softwarealso offers equipment management. The Dräger CC-Vision E-Cal software provides a widerange of different analysis and tracking functions, e.g. who a particular instrument belongs to,

High-quality test and calibration gases are required in order to test thefunction of gas detection devices effectively and, if needed, to calibratethem. Dräger test and calibration gases are produced in accordancewith ISO 9002, which guarantys a high standard of quality worldwide.They are available as single gases as well as gas mixtures.The gases are packaged in small, convenient disposable cylinders,which can be taken anywhere, thus enabling on-site function testingwith the Dräger Bump Test Station.Another advantage of the disposable cylinders is the fact that they donot need to be returned – once empty, you can simply dispose of themin an environmentally-friendly manner such as with metal waste. Thismeans no rental or transport costs to return the cylinders.

which instruments require calibration and when, and what the calibration history is for individual instruments. The software additionallyprints out a record to facilitate your data documentation. The workshopsolution also simplifies configuration of several Dräger portable gas detection instruments. The Dräger CC-Vision E-Cal software is compatible with any PC.

Purge moduleAn optional Purge Module is also available. When there is no ventialation systemminstalled this special option ensures the active anddefined suction of waste gases – some of which are toxic and explo-sive – out of the Dräger E-Cal Station.

All of the regulator valves we supply are suitable for our test and calibration gas cylinders, and permit flow rates of 0.5 l/min.

5.7 Regulator valves

For devices without internal pumps

This valve has a thumb wheel for manually opening and closing the

gas outlet.

For devices with internal pumps

This valve opens automatically when the pump draws in gas.

For the Dräger E-Cal station

This regulator valve can be used in conjunction with devices that have

internal pumps. If large, refillable cylinders with DIN 14 connectors are

being used for the E-Cal station, then this valve can also be used in

conjunction with a DIN 14 adaptor, which is also available from

Dräger.

For quick function tests prior to using a device

Pulling the trigger manually applies calibration gas briefly to the gas

detection device’s sensor. Tipping the trigger upwards fixes the

regulating valve in the open position, providing a continuous flow

of gas.

Dräger X-am 3000 and Dräger X-am 7000 are optionally availablewith an integrated high-performance pump. When you attach thepump adaptor, the device automatically switches from diffusion topump mode. This accessory enables the device to draw gas from remote measuring sites through a 20-meter-long (66 ft.) hose or, witha Dräger X-am 7000, a 45-meter-long (or 148 ft.) hose, thus enablingclearance measurements in shafts, tanks, and so on. The pump in thedevice is continuously monitored electronically. If the pump flow becomes too low – if, for example, the extension hose becomes kinked or blocked – then a pump alarm is activated on the device.

The Dräger X-am 1700/2000/5000/5600 devices can be also havethis pump function through the use of the external X-am 1/2/5000pump. When the detection device is put in to place, the pump functionstarts automatically and a flow test is initiated. Once the flow test is complete, the pump is ready for use and can be used in conjunctionwith a hose with a length of 20 meters (66 ft.). The flow test prior to every use ensures safe and reliable pump operation. If the pump flow becomes too low, then a flow alarm is displayed on the pump. An easily replaceable dust and water filterprotects the pump and the sensors in the device against dirt and contamination.

Whenever the air quality has to be assessed at a distance, such as on the floor of a silo, atthe bottom of a loading chamber on a ship, or in a sewage system, then extension hoses andpumps are needed. There are two important factors – the length of the hose and the material it is made of.

The power of the pump is crucial when deciding on the length of the hose. The Dräger X-am1/2/5000 external pump and the pump intregrated in the Dräger X-am 3000 are designedfor hoses with a length of up to 20 m (66 ft.). The Dräger X-am 7000 integrated pump issuitable for hose up to a length of 45 m (148 ft.).When choosing the hose material, you must be aware of the way the gases you are measuring are absorbed into the surface of the hose.

Three different types of hose material have proven practical, each being suitable for particular groups of gases. The following table should help you to decide which type of hoseto use.

The “CC“ in Dräger CC-Vision stands for calibration and configuration, and that describes thetwo principal functions of this software. This software application enables Dräger gas detection devices to be configured and adjusted professionally. For instance, it enables someof the device’s settings to be adjusted to the application on hand, and the sensors to be calibrated. The functions of the device are shown clearly on the screen in a tree structure, allowing quick, customized adjustment of the device’s parameters, and calibration of the sensors as well. The software also helps to manage measurment data, thus enabling quickaccess to any reports you might need to locate.

5.11 Dräger CC-Vision

5.12 Dräger GasVision

This software allows you to depict the measurement data stored in a device in table or graphic form. It shows an exposure curve for each sensor as an overview, from which segmentscan be extracted. This visualization enables hazardous situations to be recognized, and actionto be taken accordingly. Comments about the place of measurement, the personnel, andother relevant data can be added to the records, allowing you to create complete documen-tation of the situation in a workplace.

Closing comments This chapter only covers a part of our comprehensive range of accessories.
