Resistive Piezometers And Pressure Transducers

The Resistive Piezometers And Pressure Transducers also called semiconductor piezometers or strain gauge piezometers, are very accurate pressure transducers suitable for high frequency readings and short term applications. Their robust 4-20mA output signals are easy to read and automate with OMNIAlog and suitable for long-distance transmissions. They can be connected to seismic dataloggers for monitoring rapid changes in pore-water pressure such as those produced by earthquakes.
