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.
