1. General information
Bartec MTE thermostat is used to monitor the ambient temperature of heating systems as well as for the control of internal temperatures inside protective transmitter boxes or control and switchgear cabinets. In addition, it can be used for the control (signaling) of too low or too high a temperature or as an alarm contact. A temperature sensor is encapsulated in an explosion-proof metal tube. The standard version features an external M 20 thread. You can choose either a version with a cast rubber cord or one that is directly mounted to an Ex terminal box. A special version is also available with a flange fixing.
