Pressure Sensor

By Jack Burke18 December 2018

PCB Piezotronics Inc., a wholly owned subsidiary of MTS Systems Corp., has released its smallest ICP piezoelectric, pressure sensor with integral lead wires.

The company said the Model 105C pressure sensor is as robust as PCB’s larger sensors but compact enough to fit into small spaces or areas with tight clearances. The small size and stiffness of a quartz-sensing element yields a very high resonant frequency (> 250 kHz) for high-quality measurements where other piezoelectric pressure sensors cannot fit or survive, the company said.

The overall length was reduced by 48% over models with connectors, allowing it to be installed into strategic locations where unsteady pressure fluctuations and cavitation occur. For example, around impellers, propellers, or fluid jets. The sensor offers dynamic measurement from full vacuum to 100 psi (690 kPa).
