The external inputs are configured to match the external transmitter range, the units of measure, and decimal places. External 3 can be a generic 0-10V input, or when a system is ordered, configured to accept a direct plug-in of PendoTECH Single Use Temperature Sensor without the requirement of an external transmitter.

Air Detector Configuration


Integration Options

Air Detector Option: the non-invasive PendoTECH air-in-tube detector can be used as an indicator only or an alarm selectable between liquid to air or air to liquid. This could be used to shut off the pump via the alarm output signal at the end of a process step.

Pressure sensor cables provided with the system accept the PendoTECH Pressure Sensors (below). Even though these are called single use, they are robust enough to be re-used for process development work where cross-contamination is not a concern. Sizes available luer, 1/4”, 1/2”, 3/8”, 1/2”, 3/4” and 1” hosebarb, also in sanitary flange. Ultra secure tubing retainers are available for higher pressure operations.

Pressure Sensors

Other sensors such as Stainless Steel transducers with full bridge - 4 wire output may be used.

Air Detector OptionThe non-invasive ultrasonic air detector detects air in a tube placed into the detector. There is an integral LED that indicates liquid presence. The tube can be opaque because the sensing mechanism is sound waves. The software has a user entered detection delay to prevent false endpoints.

The Air Detector which detects the difference between air and liquid in a tube, is integrated into the software as an alarm or indicator only. This can be used in different ways. One example is to run a fed-batch process where liquid is continuously fed to allow a batch to be continuously added to the vessel which simultaneously concentrates. Another example is for chromatography to prevent air from being pumped into column.

Basic Flow Meters

PendoTECH Coriolis

There is basic flow meter measurement technology if the fluid being measured is clean, filtered material with relatively consistent viscosity. Ultrasonic flow measurement is available with the Leviflow Sensor with four models available covering the range from 10mL/min to 80L/min. These can be used on a single use mode or re-used and have high accuracy of +/- 1%. There is also a Low Flow Ultrasonic Flow Meter capable of measuring flows in a range of 5 to 100 mL/minute. This model has a low hold-up volume and a 1/16 inch ID x 1/8 inch OD and a luer fitting inlet fitting for easy connection. The rotary flow meters have a ¼ inch hose barb and can measure flows from about 0.1 to 1 L/min or a ½ inch barb that can measure flows from 0.3 to 20 L/min. These rotary flow meters can be used in a single use mode or re-used.

Advanced Flow Meters

E+H Mag Flowmeter

There are two flow meter inputs available for flow measurement, flux calculation, and total flow measurement. They read a digital pulse/frequency input signal that is an available output on many flow meters.


Rotary Flowmeter

When there may be a shift in viscosity flow must be measured by other types of flow meters such as the PendoTECH Coriolis Flow Meter or magnetic flow measurement technology. There are 2 models of the PendoTECH Coriolis Flow Meter covering the range from 5 to 4,000 g/minute and the E+H Promag can measure from 2 to 45L/minute.

Built-in Conductivity & Temperature Monitor

Conductivity Probe Options:

Built-in conductivity monitor also measures temperature and performs temperature compensation. There is a simple one-step calibration procedure and probes with constants of K=1 or K=10 may be used. The range is selectable from either 0-19.99 mS or 0-199.9 mS. Different flow cell or dip probe options are available.

Temperature

Temperature sensors can be used with the system and recorded in the data file.There are several options to measure temperature- either a luer fitting for small scale, and in-line hose barb sensors, and a dip probe.

pH measurement is integrated to the system. Any standard pH probe that has a BNC circular connector can be used. PendoTECH offers 2 in-line options: one for Lab/Development with either a luer or 1/4inch hose barb and one for Pilot scale with a ¾ inch sanitary flange. In both designs, the probe can be removed from the cell for calibration with buffers using the software’s pH cali-bration wizard. The lab scale probe slides past a o-ring seal to give the probe tip access to the fluid path and the hold-up volume is less than 1mL. The Pilot scale probe has a 12mm OD and is secured in the custom designed flow cell via a compression fitting. The compression ferrules are made from PTFE so they can slide up the probe or removed from the probe.

Conductivity


Integration Options

UV Absorbance Sensor & Monitor

In bioprocess operations, the UV absorbance of a liquid solution can identify the absence or presence of the molecule of interest. The measurement, typically at 280nm, is made by a spectrophotometer or photometer either in-line or off-line in a cuvette. A collimated beam of light passes through a sample with a defined path length and the absorbance is determined as the ratio of the light applied from the source to what passed through the sample. The PendoTECH Single Use UV Flow Cell enables the measurement to be made non-invasively. The flow cell is connected to tubing, and the measurement is made by use of a compact photometer with fiber optic cables. This flow cell contains a special silica glass lens on the wall and compartments to attach the light source and detector. The stream to be measured flows between the lenses by way of tubing attached to the hose barb ends of the flow cell. The flow cell is low cost for single use applications and may be repeatedly cleaned and re-used. Additionally, stainless steel flow cell options are available.

Background

Single Use UV Flow Cell Technical Details

The flow cell is shown in the pictures below with the tubing installed on the hose barb fitting. There are two sizes available- a 1/4 inch hose barb with a 0.5cm path length and a 1/2 inch hose barb with a 1cm path length. The optical interface couplers are inserted into the receptacles so the measurement can be made on the sample flowing through the cell. All polymeric materials in fluid path meet USP Class VI and it is assembled in an ISO13485 facility. The flow cell may be autoclaved to 121°C or gamma irradiated up to 50KGy.The compact photometer with its 4-20mA transmitter function, connects to External 1 or 2 on the DAQ. The raw output of the transmitter output in is a 4-20mA signal spanned to 0-2 AUs. The standard wavelength is 280 nm but other wavelengths from 240-1000 nm (with 260 being common) are available, but may not be interchanged by user.

PendoTECH Turbidity Flow Cell & Measurement Unit

In bioprocess operations, the turbidity of the liquid after a filter can be measured as an indication of filter performance. It can also be used to mea-sure unclarified material such as directly from a bioreactor or fermentor. The measurement may indicate that undesired components are “breaking though” the filter meaning the filter is losing its capacity. The turbidity measurement at 880nm can be used in conjunction with pressure measure-ments in constant flow filtration processes to give an overall measurement of filter performance. To make a turbidity measurement, a sample may be drawn and measured off-line or an on-line measurement may be made with a device such as the PendoTECH Turbidity Flow Cell.

Background

Technical Details

The complete setup is shown in the following picture.

The raw output of the transmitter is a mA signal that is scaled from 0 to 2 absorptions units (AUs) and this connects to External 1 or 2 on the DAQ. Conversion to units such as NTUs can be made by adjusting the maximum range (20mA value) on the DAQ software after the conversion factor is determined or just AUs can be recorded.

Fiber Optic Cables

Flow Cell

Measurement unit with transmitter

Cable to connect transmitter to control system

The PendoTECH turbidity sytem operates on the principal of light scattering of particles at 880nm, which is the traditional wavelength for turbidity measurements. The raw reading of the instrument is absorption units (AUs). This can be directly correlated to NTUs that are the typical units of measurement for turbidity. The correlation of AUs to turbidity is based on the path length.

NTU Standard Measurement

With 6.5 cm path length: With turbidity standards 0-2 Au correlation range = approximately 300 NTUsWith 1 cm path length: With turbidity standards 0-2 Au correlation range = approximately 1900 NTUs

However, the correlation may vary between samples from different processes. For best results a product specific correlation from AUs to NTUs may be determined with two offline measurements.

Measuring Turbidity

Instrument ResolutionDue to the compact low hold-up design of the PendoTECH flow cells only forward scattering of light is measured. This results in a repeatability of +/- 1% of full scale measurement. For 6.5 cm path length the instrument can achieve +/- 3 NTUs repeatability, while the 1 cm path length results in approximately +/- 20 NTUs. The instrument is ideal for measuring process trends but cannot measure fine changes beyond the capabilities of the unit.
