Pressure Transducers

Pressure Transducers

The Gräff series are Mercury & Silicone Oil free, using an innovative liquid metal alloy with pressure transfer characteristics similar to Mercury. Pressure ranges vary from 100 bar to 2000 bar, with output signals of 2.0 mV/V, 3.3 mV/V, 0-10VDC or 4-20 mA available. All outputs have a calibration signal of 80%. Normal precision of accuracy is 0.75% FSO with the option of 0.25% or 0.50%.

Supplied with ½”-UNF20 fitting as standard, probe length is usually 76mm or 152mm with other lengths upon request. Terminated with 6, 7 or 8 pin connectors, sensors can be supplied with additional flexible capillaries up to 760mm & can also include an integrated Type ‘J’ (Fe-CuNi) Thermocouple.

For use with our range of Pressure Transducers we also supply the Gräff series GMDA-3 Pressure/Transmitter Indicator.
