143-216-000-051 Vibration Gauge Piezoelectric Force Sensor vibro-meter 143-216-000-051

Utilizing VC2 single-crystal piezoelectric material, the sensor offers superior performance compared to standard piezoelectric ceramics—specifically, minimal sensitivity drift at high temperatures, low long-term creep, and excellent temporal stability—making it ideal for years of continuous online monitoring; it features a fixed sensitivity of 25 pC/bar. It boasts a dynamic range of 0.0005 to 250 bar with a short-term overload capacity of 350 bar, enabling it to withstand instantaneous pressure spikes during combustion. The design incorporates a compression-mode crystal configuration and an internal housing insulation design. With a natural resonant frequency of 80 kHz—well above the upper limit of the operating bandwidth—it ensures stable phase and amplitude responses across the 2 Hz to 15 kHz measurement range; additionally, an acceleration sensitivity of ≤0.0625 pC/g significantly minimizes measurement crosstalk errors caused by housing vibration.
