Introduction

The 24PC Series Miniature Pressure Sensors are small, cost- effective devices intended for use with wet or dry media. These sensors feature proven sensing technology that uses a specialized piezoresistive micromachined sensing element to offer high performance, reliability, and accuracy. Each sensor contains four active piezoresistors that form a Wheatstone bridge. When pressure is applied, the resistance changes and the sensor provides a milliVolt output signal that is proportional to the input pressure. The low power 24PC sensors are designed to accommodate pressures from 0.5 psi to 250 psi and have an operating temperature range of - 40°C to 85°C [- 40°F to 185°F] The 24PC sensors have the flexibility to be excited with constant current or constant voltage. When driven by constant current, the pressure sensor's terminal voltage will rise with increasing temperature. The rise in voltage not only temperature compensates the span but also provides an indication of the sensor's temperature. These sensors can accommodate a variety of wet and dry media that are compatible with polyphthalamide (PPA) plastics and media seals specified in the Nomenclature and Order Guide. The 24PC sensors are RoHS compliant. They are designed and manufactured according to ISO 9001 standards.
