Relative pressure sensor 101B(a19F)

absolutepiezoresistiveanalog

Model 101B(a19F) pressure sensor (PS) is designed with a completely flush diaphragm in its front. Compared to the diaphragm of 101B(a19G) PS, 101B(a19F) features no any raised edge at its diaphragm. This feature is especially useful when the PS measures the pressure either of sticky pressure medium, like viscous paste, or of pressure medium containing solid particles, like wasted water. The completely flush diaphragm brings the 101B(a19F) PS with advantages when the PS is used to constitute 2-D or 3-D sensor arrays, which are commonly used to measure pressure distribution in relevant space of liquids. Both its diaphragm and its housing are made from 316L stainless steel. Therefore, the 101B(a19F) PS can measure pressures of corrosive or/and conductive pressure medium as long as the medium is compatible to 316L stainless steel. The same as 101B(a19G), the 101B(a19F) PS has a piezoresistive pressure sensor die integrated inside the PS and its capsule is filled with un-compressive oil. A variety of output signals are available, e.g., mV/V signal directly from the Wheatstone bridge circuit, ratiometric signal of 10%~90%Vs, or digital signal of I2C or SPI protocols via an SSC which is fixed at the PS backside.
