Measure very high pressures from 1000 to
5000 bar
The TPH High Pressure Transducer and the TPHA High Pressure Transmitter can measure very high pressures from 1000 bar (15000 psi) up to 5000 bar (75000 psi) in a range of applications
The TPH High Pressure Transducer and the TPHA High Pressure Transmitter can measure very high pressures from 1000 bar (15000 psi) up to 5,000 bar (75000 psi) in applications which include high pressure testing, hydraulic fatigue testing, burst testing, destructive testing, machine hydraulic systems such as water cutting machines, diesel injection testing and ultra-high pressure sterilisation for the food industry The sensing technology of the TPH and TPHA High Pressure Sensors incorporate an extremely reliable 15-5ph stainless steel diaphragm with proven photo engraved metal leaf strain gauges formed into a four arm Wheatstone bridge circuit to provide a robust pressure sensing assembly which performs well in systems which exhibit high over-pressure spikes and cavitations

Industrial and precision pressure transmitters incorporate versatile zero and span trimmer that removes the need to adjust potentiometers or use handheld terminals to set the 4 to 20mA current output.
Display plugs in for pressure readout
A novel loop-powered display simply plugs-in between the DIN plug and socket of a pressure transmitter to provide a local indication of the pressure reading.
The standard ranges available for the TPH and TPHA are 1000bar, 1500bar, 2000bar, 3500bar and 5000bar and the sensor can be scaled to any range from 1000 bar to 5000 bar as a special execution.
The accuracy for all ranges is 0.3% of full scale including linearity, hysteresis and repeatability.
For high dynamic response applications the TPH pressure transducers unamplified output signal of 2mV/V makes full use of the frequency response of the measurement diaphragm which ranges from 18 to 80 KHz at full scale pressure.

No waiting for pressure transmitters
The popular Gefran TK industrial pressure transmitter is now available from stock.
The TPHA electronics package offers zero and span adjustment for fine tuning the pressure transmitters amplified voltage or current output signal which are easily accessible via the 2 fixing screws which are located along the body of the sensor.
There is also an integral calibration signal that can be selected for simulating an applied pressure when scaling or calibrating an instrument for use with the TPH or TPHA.
The flexible electronics design provides a variety of output signals of 4-20mA, 0-10V, 0-5V, 1-5V.
Due to the very high pressure range of the TPH and TPHA only 2 pressure connections are offered which are the F-250-C (9/16-18UNF) female autoclave fitting and the M16x1.5 female.
As standard a DIN43650 plug (IP65), Bendix military style electrical connector (IP66), or integral cable can be selected for the electrical interface to suit the environment in which the sensor will be used.
The TPH and TPHA family of High Pressure Sensors has been developed solely for the measurement of very high hydraulic pressures and has all the necessary product features that you would expect for hydraulic applications such as high dynamic response, durable and reliable diaphragm, and high integrity mechanical construction.
