pH transmitter range with isolated 4-20mA output

pH Transmitter Range

Within our pH Transmitter range, we offer the P3630 pH Transmitter. This instrument is ideal for pH applications where the pH electrode is more than 50 metres away from the instrumentation, as well as transmitting a pH signal to a PLC or other device.

The unit is normally located within close proximity to a pH electrode, giving the operator a visual indication of the current pH output.

The pH Transmitter then transmits the pH value using a 4-20mA (or 0 - 20mA) current signal to a PLC or Chart Recorder which can be located up to 1000 metres away. The same 2 wires which transmit the pH signal as a 4-20mA current signal are also used to power the pH transmitter. This "loop powered" system ensures an efficient transfer of the signal and means that the pH transmitter can be housed in either a small din rail mounting enclosure or as a surface mounted pH transmitter system.

P3630 pH Transmitter

P3630 pH Transmitter

The P3630 is a field mounting pH transmitter can transmit a 4-20mA control signal proportional to the pH over a distance of up to 1000 metres away.

Designed for integration with PLC's, data loggers, BMS systems and 4-20mA controllers the P3630 features local zero and span settings for simple calibration of the pH electrode system.

The P3630 can be loop powered - which means that when connecting to a remote system the same 2 wires which carry the 4-20mA signal also provide power to device making installation as simple possible.
