Gas detection systems in automotive test chambers

Depending on the specification of the individual test chamber the temperature can vary between -40 °C and +90 °C. In many cases the humidity in the test chambers can vary from 5% up to 95% RH. These particular conditions often represent a major challenge for both the test objects and the gas warning devices. The changes in

Steam Sterilization Principles & Common Mistakes Using ...

Wet steam can cause condensate to be introduced into the chamber during the test preconditioning pressure pulses. Any condensate in the chamber will evaporate at the test vacuum level, causing a rise in chamber pressure. One practical way to determine the source of the pressure rise is to observe the leak rate during the vacuum hold phase with an absolute pressure gauge connected to the ...

Lambda sensor testing and troubleshooting | HELLA

The broadband lambda sensor offers the option to measure a precise air ratio in both the lean (λ > 1) and rich (λ 1) ranges. It delivers an exact electrical signal and can therefore control any reference values – for diesel engines, gasoline engines with lean concepts, gas engines, and gas heaters. Like a conventional probe, the broadband lambda sensor is built up with reference air ...
