They can be operated at 5 Vdc to give 0…50 mV signal or 20 Vdc to give 0…200 mV signal. The circuit is a compensated resis-
tance bridge and is completely passive with no diodes or reactive components. Bridge resistance is 3,5 kΩ nominal.
The 6…28 V supply transmitter is fitted with an internal regulator. The mPm connector has a PG7 cable gland entry suitable for
cables between 4 and 6 mm diameter. Screw terminals and solder lags are provided. The G 1/4 pressure connection has an
integral Viton
