Miniature Low Pressure Flow-Through Sensors 24PC Series, Uncompensated/Unampliefi d 0.5 psi to 250 psi DatasheetMiniature Low Pressure Flow-Through Sensors The 24PC Series Miniature Low Pressure Flow-Through 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 piezoresistive elements in a Wheatstone bridge configuration. When pressure is applied, the resistance changes and provides an output signal in mV proportional to the input pressure. The pressure sensor is typically excited by constant current. When driven by a constant current source, a silicon pressure sensors terminal voltage will rise with increased temperature. The rise in voltage not only compensates for the span but also provides an indication of sensor temperature. The low power, uncompensated, unamplified Wheatstone bridge circuit design offers 0.5 psi through 250 psi sensing ranges in a variety of pressure port types and termination configurations. The mV output is available in both negative and positive voltage. These sensors are intended for use with media compatible with plastics and media seals specified in the Nomenclature and Order Guide (see Figure 2). They are designed and manufactured according to ISO 9001 standards.
