Sitron's Pressure Sensors SP96 and SPC98 provide cost effective, reliable and accurate level and pressure measurement. These sensors are suitable for absolute pressure as well as for positive and negative gauge pressure. Like all of Sitron's products, the Pressure Sensors can be made in a wide variety of process connections. They feature easy installation (mounted at the bottom of a vessel), within a compact design. They also feature excellent repeatability, high accuracy, and maintenance-free reliability under varying environmental conditions.

As the volume of the medium increases within a tank or well, the process pressure is applied to a 316 S.S. piezoresistive diaphragm cell (SP96) or a ceramic cell (SPC98). The external force of the process pressure creates a displaced electrical charge, which accumulates on opposing surface of the cell. In both cases this generate an output signal, which is converted to a standardized 4-20-mA (2 wire) signal that is directly proportional to the pressure applied.

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.
