ISSO-PC1/PC2 Vibrating Wire Earth Pressure Cell

Ground pressure sensors ISSO–PC1/PC2. The principle of operation of the sensors is based on measuring the resonant frequency of vibrations of a string stretched in their body. In sensors, a change in the measured pressure value leads to a change in the time characteristics of the electrical output signal. When the pressure acting on the sensor membrane changes, the tension force of the string changes. The vibration frequency of the string is proportional to the measured pressure.

The sensors have a significant overload capacity of 50% of the nominal measuring range.

Precision and durability. The combined use of a hydraulic pressure sensing chamber and a vibrating string transducer ensures high accuracy, long-term stability and resistance to external electromagnetic interference.

The sensor is capable of operating in a wide temperature range from -45°C to +80°C.
