DESCRIPTION
The sensor element of Implanted resistors make use of the piezo-resistive effect to sense the membrane deflection and transform it in an electrical signal. The Pyrex glass wafer used for this sealing has a thickness of 0.2 mm (MS7902-A_0.2) or 0.5 mm (MS7902-A_0.5). There are two gauge versions available: one with a drilled Pyrex glass (MS7902-D) and the other without Pyrex glass (MS7902-S).FEATURES
