Pressure transmitters & transducers that are resistant to chemical corrosion for measuring the hydrostatic level of storage tanks or process pressures.
Plastic based pressure sensors suitable for direct contact with corrosive liquid chemicals. Caustic chemicals are highly corrosive to metals and thin metal diaphragms can be quickly eroded ultimately causing mechanical failure.
In these applications it is best to use pressure sensors with plastic housings and Ceramic diaphragms which are resistant to aggressive chemicals. These pressure sensors have semi-flush ceramic sensing diaphragms for corrosion protection & easy cleaning. The sensor housings are made from PVDF, PVC, PP or stainless steel for compatibility with aggressive chemicals.
DMK 331 Ceramic Diaphragm Industrial Pressure Transmitter - This pressure transmitter can be supplied with a PVDF process connector so that it can be used to measure the pressure of acids and other corrosive chemicals.
