The SPC98 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, applications with solid particles and low pressure ranges. It is designed to be installed at the bottom of the tank. As opposed to the 316S.S. piezoresistive cells filled with oil, the process pressure acts directly on the ceramic diaphragm.

The actual measuring range of the sensor is determined by the thickness of the ceramic diaphragm, which if overloaded, stops on the ceramic substrate without sustaining damage. Ceramic cells do not expand and contract nearly as much as metal, ensuring good temperature stability.Common features of the SPC98 are low hysteresis, high repeatability, immunity to the effects of process builds up and outstanding resistance to chemical attack.

The SPC98 is often specified for sanitary applications because if the ceramic cell breaks it will not contaminate the process medium. The SPC 98 provides a 4-20mA output and its body is made of 316S.S.

Pressure ranges from -1 to 580PSI (-1 to 40 bar) gauge /absolute.
