How to choose this product
thermostat

A thermostat measures ambient temperature and compares it to a reference setpoint for control purposes. Depending on the difference between the two temperatures, it triggers the heating or cooling of the surrounding space.

Applications

These devices are found wherever a constant temperature must be maintained. They are used in HVAC installations for ambient climate control. They are also common in industrial facilities and in laboratories to keep water baths and refrigerated compartments at a constant temperature.

Technologies

Mechanical instruments operate using the principle that certain substances expand when heated. These include bimetallic versions, liquid-filled capillary models and gas expansion thermostats. Electric thermostats consist of a temperature sensor, such as a Pt100 or a thermocouple, and a relay to actuate a heating or cooling device. They can be individually configured.

How to choose

Choice will depend on the specifics of the intended application. These include the area or system whose temperature is to be controlled, available installation space and related practical factors. The thermostat should be placed where temperatures are representative of the entire system.
