The APB2S range of sanitary pressure transmitters have a flush diaphragm which is suitable for the measurement of viscous fluids or media containing particulates that may clog the pressure connection of standard transmitters.
The transmitters have piezoresistive technology which incorporates a silicon sensor. The diaphragm and wetted parts are 316L stainless steel.
The stability of the silicon element allows the transmitter to be operated at a higher temperature range; at the same time this makes the zero and sensitivity thermal shifts over the whole operating temperature range of the transmitter very small.
