Pressure transmitters for general purpose applications measuring air and liquid pressures on pumps, valves, compressors, hydraulic presses and automated machines.

Low range pressure transmitters for measuring low level gauge, differential and absolute pressures below 1 bar (15 psi, 400 inWG or 1000 mbar).

Mid range pressure transmitters for measuring pressures between 1 and 100 bar (15 to 1500 psi).

High range pressure transmitters for measuring hydraulic pressure greater than 100 bar (1500 psi) with a range of accuracies, electrical interfaces and pressure connectors.

Loop powered 4-20mA readouts for combining with pressure transmitters to provide a local display at point of measurement without the need for batteries, extra wiring or mounting brackets.

Digital panel meters for providing loop power and reading 4 to 20mA output pressure transmitters with LED displays, peak hold, alarm relays, Triacs, retransmission analogue outputs and digital interfaces.

Differential pressure transmitters for measuring the DP of fluids and gases across particle filters and along a length of pipe to monitor flow.

Absolute reference pressure transmitters for measuring pressures with respect to absolute zero vacuum.

ATEX approved pressure transmitters for use in hazardous zones with flammable gases present such as petrochemical refineries and natural gas distribution pipelines.

High precision pressure transmitters with good non-linearity, hysteresis and repeatability for highly precise measurements.

Rangeable pressure transmitter which can be either digitally or manually down ranged by the user to scale the 4 to 20mA current output signal to a different pressure range.

Flush fitting pressure transmitters with 4 to 20mA current loop signals with exposed diaphragms for measuring viscous media or substances which require hygienic or sanitary compatibility.

HART protocol compatible pressure transmitters for configuration via a pc, laptop, distributed control system or HART communicator. HART functionality enables the transfer of pressure transmitter data via an AC digital signal which uses the 4-20mA analogue output signal as a carrier, thus eliminating the need for extra wires and connectors.
