The SP96 pressure transmitter or sensor is made with 316S.S. piezoresistive cells filled with silicone or oil. It is design to be installed at the bottom of the tank. There are advantages (such as wide frequency and amplitude range) to use piezoelectric sensors. Fast response, rugged and compact 316 S.S. housing and temperature compensation are standard features of the SP96.

The SP96 pressure sensor is offered in 316 S.S. with a 4-20mA output signal, as well as a great variety of pressure ranges and connections. The SP96 pressure sensor can also be offered with a zero and span adjustment. The SP96 models can be easily customized to handle a wide range of applications for different types of liquids, as well as for gases.

The SPC 98 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 and extreme min/max temperature 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 SPC 98 are low hysteresis, high repeatability, immunity to the effects of process builds up and outstanding resistance to chemical attack.

The SPC 98 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.
