The SP98 dry and flush mounted ceramic pressure sensor uses an aluminum oxide ceramic sensor as a “dry cell” that is extremely resistant to overload, aggressive mediums, extreme min/max temperature, applicationswithsolidparticlesandlowpressureranges. Asopposedto the 316SS. piezoresistive cells filled with oil, the process pressure acts directly on the ceramic diaphragm. It is designed to be installed at the bottom of the tank.
Ceramic cells do not expand and contract nearly as much as metal, ensuring good temperature stability. Common features of the SP98 are low hysteresis, high repeatability, immunity to the effects of process builds up and outstanding resistance to chemical attack. The SP98 is often specified for sanitary applications because if the ceramic cell is broken it will not contaminate the process medium.
The SP98 provides a 4-20mA output and its body is made of 316SS. Pressure ranges from -1 to 580PSI (-1 to 40 bar) gauge /absolute. Also available with optional 4…20mA + HART output.
