Product Features

The explosion-proof temperature thermostat is used in conjunction with the electric heating cable to control the temperature of the heat tracing pipe on site, so that the medium temperature can be controlled within the temperature range required by the process, thereby protecting the electric heating cable and saving energy. It is designed and manufactured according to the requirements of increased safety explosion-proof electrical appliances. Applicable to the explosive gas environment in the first and second zones of the factory.

Before installation, please carefully check the temperature controller (such as damage, deformation, looseness, etc.), otherwise it is not allowed to install and replace it in time. Turn on the temperature controller to find the temperature adjustment knob, adjust to the room temperature to hear the sound of the relay action, and use a multimeter to measure the on/off status of the corresponding terminal. Normally adjust the temperature to the temperature you want to control and tighten the lid. When connecting the internal wiring, the connecting wire should be tightened. It is strictly forbidden to entangle the cores in the terminal box to ensure sufficient electrical clearance. The size of the sealing rubber ring should be matched with the size of the heating cable during installation, and it should not be exchanged at will to ensure the explosion-proof performance. All fixed screws are tightened to ensure explosion-proof performance. Fix the temperature controller in place with the clamp and attach the temperature probe to the temperature of the measured temperature. The temperature control probe should be horizontal or vertical and keep a certain distance of 3-5cm from the electric heating cable to avoid measurement. The temperature of the equipment is not accurate or unstable.
