Sensor Technology

Choose a pressure sensor with a specific type of diaphragm sensing technology that is the most suitable for your application.

Pressure transducers & pressure transmitters with silicon strain gauge sensing diaphragms which have output signals with good linearity, hysteresis and short term repeatability. Semiconductor pressure sensors also have high overpressure ratings and sensitivity due to the high gauge factors of the semiconductor strain gauges.

Hydrostatic pressure sensors with silicon semiconductor strain gauge diaphragms which offer high accuracy for low to medium range liquid level measurement. The small surface area of silicon chips is ideal for incorporating into the design of small diameter submersible sensors which are lowered down narrow boreholes as part of groundwater surveys.
