The 23 Ed flame proof pressure transmitter has a silicon strain gauge sensing element which provides good linearity, hysteresis and repeatability over the pressure measurement range to 0.5% full scale best straight line as standard, which can be approved to 0.2% or 0.1% if necessary.

The 23Ed flameproof pressure transmitter is available with low pressure ranges from 3 psi up to 300 psi vented gauge or absolute plus high pressure ranges from 15 up to 4500 psi sealed gauge.  Suction pressures from -3 psi down -15 psi gauge can also be specified for measuring vacuums.

The output signal of the 23Ed flame proof pressure transmitter can be 2 wire 4 to 20 milliamps, 3 wire 0 to 20 milliamps or 3 wire 0 to 10 volts.  A polyurethane jacketed cable is provided for the electrical connection which is sealed at the backend to IP65.  For vented gauge versions a Polyethylene jacketed cable is used which includes a vent tube for the gauge reference pressure.
