Explosion-proof programmable thermostat GTG-PT (SA-TERMOSTAT-D)


Explosion-proof programmable thermostat GTG-PT is applied for control of external electrical devices and mechanisms depending on ambient temperature or the object of measurement. Explosion-proof thermostat GTG-PT is used for automation of processes, maintaining preset temperature condition or for the protection of monitored object from exposure to ambient temperature. Temperature measurement occurs once per second with accuracy 0.5°С.

Explosion-proof programmable thermostat GTG-PT is structurally designed to be enclosed in a single housing with removable front cover with window made from impact-resistant antistatic armored polyester, control buttons arranged on the right side of the device and remote intrinsically safe heat sensitive element with flexible conductor. Two explosion-proof cable glands are provided for connection of external devices and power supply.

Explosion-proof digital temperature sensor is a solid state digital measuring element enclosed in the housing with selected type of mounting and a flexible conductor that provides data communication to the computing device. Input of flexible conductor into the enclosure is performed via cable gland.  

The device has emergency mode of operation that switches on when the thermostat loses signals from the sensor due to line break or failure of the sensor. The design of GTG-PЕ allows for replacement of the sensor.

Examples of use of explosion-proof programmable thermostat GTG-PT:
- Monitoring of room temperature and maintenance on the preset level by switchen the heating or cooling device on;
- Power circuit safety cutout in case of overheating or excessive cooling;
- Maintenance of the controlled object in preset temperature mode;
- Fault signaling or temperature threshold exceeding by means of connection of light signaling accessories.
