Industrial 772-211 Analog Output Process Controller

Description:

The Thornton 772-211 Analog Output Process Controller is used in industrial water analysis systems to monitor, display, and control conductivity, resistivity, pH, temperature, and other process parameters while providing analog output signals for process automation. Commonly installed in pharmaceutical water systems, semiconductor manufacturing facilities, power generation plants, ultrapure water systems, and industrial water treatment processes utilizing Thornton analytical sensors. Maintenance technicians and system integrators use this controller for instrumentation upgrades, process control repairs, sensor integration, and replacement of legacy water quality controllers.

Applications:

The Thornton 772-211 process controller continuously measures process variables from compatible Thornton sensors and provides dual isolated 4–20 mA analog outputs for connection to PLCs, DCS, SCADA systems, and recording devices. It is widely used in reverse osmosis systems, deionized water plants, water-for-injection (WFI) systems, boiler feedwater monitoring, clean-in-place (CIP) systems, and semiconductor ultrapure water applications where continuous process monitoring and analog signal transmission are required.
