Thermographic Application in Measuring Technology according all parts of IEC 60079

Specifications: min. size of test objects components in SMD-technology

max. size of test objects environment

Temperature range (-20 °C to +1500 °C)

Scope: To measure surface temperatures by means of athermal imaging camera and to visualise the temperatures as a miscoloured picture or film

To measure the component itself during construction stages and repair work

To detect faults at faulty electronic components

Infrared thermal imaging for use in fire prevention

Research and development

Additional features: The measuring process records all parameters of the test object and evaluates them individually according to the client‘s needs. It runs through any thermal cycles required by either standards or client settings. Moreover it allows to detect hot spots that can be analysed by means of a specific software.

Clients: Manufacturers of explosion-protected apparatus as well as non-protected apparatus.

Storage conditions (temperature/climatic) according all parts of IEC 60079

Specification: max. size of object I (45 x 35 x 200) cm

max. size of object II ( 50 x 50 x 50) cm

max. size of object III ( 200 x 110 x 110) cm

temperature range I ( 0 °C to + 200 °C)

temperature range II (- 70 °C to + 250 °C)

temperature range III (- 40 °C to + 180 °C)

rel. humidity up to 90 % in case of temperatures up to + 95 °C

Task: to create artificial ageing

thermal cycling using temperature profiles

preparing test for further tests

to eximane the life expectancy incl. functional test

Further services: During the storage period all measurements of relevant key indicators shall be recorded and individually evaluated on request. Standardised thermal cycles or those provided by the costumer shall be run through. Additionally, hot spots shall be detected and analysed using thermal camera.

Clients: Manufacturer of electrical equipment for use in explosive atmospheres,

Suppliers to the automotive and rail industrie.
