1. General information
Bartec DTW temperature monitor is flame-proof encapsulated designed for (trace)-heating applications in the Ex area, switching capacity 22A.They can be used both for protection against frost and for maintenance temperature applications. Heating units and other operating equipment are switched on and off by means of the temperature controller when the temperature is too high or too low. The DTB temperature limiter is designed with resetting lockout; resetting (restarting) is only possible on the device. Can be used for monitoring temperature in the air or on surfaces..
A change in temperature in the sensor causes a change in volume in the fluid filled in the measuring system, which in turn results in a movement of a membrane, which is connected to transmission mechanics and activates a micro switch. If the sensor temperature exceeds the pre-set level, the contact is actuated. The temperature limiter switches off permanently if the temperature is exceeded. Once the temperature drops, the temperature limiter can be unlocked manually. If there is a break in the measuring system (leakage), the circuit remains open permanently.
