Pressure Transducers - Sensors for Test & Measurement

The full line of PCB® of piezoelectric pressure sensors are used for a variety of dynamic pressure measurements.

The ability to measure small pressure fluctuations at high static pressure levels is a unique characteristic of piezoelectric pressure sensors. With ICP® amplified output, the transducers are well-suited for continuous operation in “dirty” environments, underwater, and in field test applications across long cables. Special low-noise cable and charge amplifiers are not required. These sensors are ideal for virtually all dynamic pressure applications where sensor temperatures range from -320 to +275 °F (-196 to +135 °C). For higher temperature applications, charge output sensors are available for use up to +750 °F (+399 °C).

Although piezoelectric pressure sensors are primarily recommended for dynamic pressure measurements, some quartz pressure sensors have long discharge time constants that extend low-frequency capability to permit static calibration and measurement of quasi-static pressures over a period of a few seconds.

Solid state construction of a piezoelectric pressure transducer provides a wide linear measuring range such that PCB® confidently provides calibrations at 100% and 10% of full scale output for most models.

To discuss specific applications, or if a special pressure sensor or adapto is required, please contact PCB® for assistance.
