PHMA pH Transmitter, 4-20mA, Blind by Sensorex

The Model PHMA (encapsulated miniature transmitter) is a 2-wire, 4-20 mA pH transmitter featuring encapsulated construction, high performance and small size. It can be interfaced with many display and control devices requiring a 4-20 mA input.

The unit is compatible will all SensoreX conventional combination pH electrodes. It transforms the pH signal to a 4-20 mA current proportional to the pH level. This output may be transmitted over two wires to a control location. The same two wires provide power to the transmitter. Any 12 - 36 Volt D.C. power supply may be used. There are two adjustments on the transmitter to standardize probes for "SPAN" and "ZERO". The output can be monitored with a loop-powered meter, a loop resistor or even a multi-meter during the standardization procedure.
