NON-WETTED
Housing
PBT (meets UL94-VO)
Featuring a highly reliable variable capacitance sensor using the patented
Ashcroft® Si-Glass™ sensor. This ultra-thin single crystal diaphragm provides
inherent sensor repeatability and stability.
Sensor Cross Section
The silicon diaphragm sensor has no glues or
other organics to contribute to drift or
mechanical degradation over time.
