Product overview
PM35 flat membrane pressure transmitters are suitable for food, beverage, pharmaceutical and bioengineering applications. The direct welding of the all-metal flush diaphragm to the process connection ensures a precise connection between the process connection and the measuring diaphragm. Therefore, no additional sealing gasket is required, and no measurement dead zone is guaranteed.
The diaphragm made of stainless steel 316L separates the measuring medium from the pressure sensor. The process pressure from the diaphragm to the piezoresistive sensor is transmitted statically through the filling fluid, which passes the sanitary approval.
