Temperature Controllers Product Description

Global Water’s Temperature Controllers are high performance industrial grade digital indicating, single set point proportional/On-Off controllers for use with type K, J, T and E thermocouples. Thermocouple gain and cold junction are automatically compensated by the Temperature Controller’s internal electrode circuits. An accurate 1 mV per display count analog output is provided to interface the Temperature Controller with a recorder, printer and so on. The Temperature Controller uses a bright red LED screen.

The Temperature Controllers are a single set point proportional/On-Off controller. The proportional bandwidth is adjustable from On-Off to 100 °C or 100 °F with built-in hysteresis. The cycle time is factory set to 20 second ± 3 seconds. The Temperature Controllers have a front panel manual adjust reset potentiometer.

The Temperature Controllers are 1/8 DIN front panel mount inside of a plastic housing. Temperature controller probe connections are made via spade lug connectors.
