Main Features
-> The design is small and tough, with a stainless steel flange and metal-sealed construction for long-lasting use.
-> The tungsten filament and glass feedthrough make it possible to make reliable measurements based on thermal conductivity.
-> The analog output signal (2.2–8.5 V) makes it easy to connect to controllers like the TPG series.
-> IP40 protection and low power use (≤1 W) make it good for labs and factories that need to run all the time.
Usage:
The TPR 280 from D-35614 Semiconductor fabrication operators use Asslar to maintain the proper vacuum during wafer processing and thin-film deposition. Coating companies utilize it to monitor chamber pressures in PVD and CVD systems, thereby ensuring consistent layer quality. It is used in research facilities and analytical instruments to find leaks and test the functioning of pumps in mass spectrometry setups.
