WA16 Diffused Silicon Oil-filled Sensor
WA16 series are MEMS technology based piezoresistive silicon sensor. It is a kind of high stable and high accuracy OEM preesure measurement sensor. This series are sealed with pressure diaphram of international well-known manufacturers. The external pressure is passed to sensitive elements through 316L stainless steel diaphram and internal silicon oil. Thus it can be used to measure all pressure media compatible with 316L stainless steel.
Every sensor was strictly temperature compensated for both zero and span before shipment to ensure measurement accuracy in complex environment.
This series sensor offers two excitation power -- constant current and constant voltage (for details please check technical parameters and type code ). It also matches varied-size threads so is able to meet requirements of different customers.
