Temperature Sensors
Application:
Temperature sensor type CZT-1 is intended to supervise the temperature of devices components, as well as non-aggresive liquids: water, oils, oil-water emulsions etc.
The sensor cannot be used to control the temperature of aggresive media.
Performance:
Temperature sensor is equipped with bimetallic bistable thermostat. Under the influence of temperature, opens or shorts the sensor contacts, as a result closes or cuts the control loop of a device, where the sensor was adopted. Thereby the automatic stop of a device is possible, in case the permissible temperature exceeds its limits.
