Low cost, two-wire, 4-20 mA transmitters for pH interface to PLC and dataloggers
For those that need to connect their pH electrode to a programmable logic controller (PLC), data logger, or any other 4-20mA device, Sensorex is pleased to offer two-wire 4-20 mA pH transmitters. These transmitters convert your pH electrode's mV signal into a mA signal.
The best choice is our new TX100 two-wire pH/ORP transmitter. It features a local display for real time measurements and aids in calibration. Packed with powerful features, this unit features an array of user selectable options as well as input to output isolation and a multitude of mounting options—all for a fabulous price slightly more than the PHMA. Units require 12-36VDC power. To learn more, Download specs:
