The model 101B(f) pressure sensor features a flush diaphragm made from 316L stainless steel, which contacts directly to pressure medium when the sensor is in operation. Compared to 101B(a19F, a19G, a19L)-series pressure sensors, the 101B(f) pressure sensors possess 1/2G threads for pressure connection by SW27 hexagon for mechanical installation. As a result, the 101B(f) pressure sensor can be easily turned into a pressure transmitter by adding both an SSC (sensor signal conditioner) at its backside and a housing via its M25x1 threads.
Like 101B(a19F, a19G, a19L)-series pressure sensors, inside the 101B(f) pressure sensors a piezoresistive pressure sensor die is bonded on a sensor header and is completely surrounded and covered by un-compressive oil. The oil is fully filled in a cavity which is formed by the flush diaphragm and the sensor header. Therefore, when pressure is applied to the flush diaphragm the oil transfers the pressure to the sensor die, and the sensor die measures the pressure.
Thanks to the feature of the stainless steel flush diaphragm, the 101B(f) sensors are able to measure pressure of either viscous paste or fluids containing solid particles. The pressure medium can be corrosive or conductive as long as it is compatible to 316L stainless steel.
