Sentek has a new pH/ORP sensor to PLC interface module that uses a PLC as an ultra-flexible pH/ORP transmitter.
Sentek has a new pH/ORP sensor to PLC interface module that uses a PLC as an ultra-flexible pH/ORP transmitter.
The module provides a galvanically isolated 4-20mA DC output to a PLC which is representative of the pH/ORP sensor measurement range.
Advantages include the ability to perform multiple sensor monitoring and process from one PLC - eliminating the need for a dedicated analyser for each sensor.
Also, free chlorine residual calculation is a simultaneous pH and ORP analysis.
