temperature controller maintenance, temperature controller manufacturer remind everyone: in order to ensure the long-term reliable operation of the temperature controller when checking the condition of the instrument, the following must be done:
1. The heat transfer coefficient of the sensor and the measuring substance should be excellent, and it should be installed in the position where the specific temperature of the measuring block can be displayed properly and immediately.
2. all electrical connections of the temperature controller must be in good contact. the input, output and power lines of the instrument should not be exposed, so as to avoid conducting electricity with other conductors. Of course, the temperature controller should not be used in an environment with corrosive gases.
3. temperature control device has LL or HH, the machine equipment does not heat up, be sure to check whether the sensor is disconnected, short circuit fault or reverse connection. Check whether the power supply voltage is normal and whether there are strong magnetic fields in the operating environment.
4. when the output light of the instrument is on, the instrument indicates that the instrument has output. if the equipment is not heated, check whether the wiring of the heating equipment is correct and whether the heating pipe is normal. If all of this is good, it may be the problem of the instrument and equipment itself, usually the instrument and equipment with short circuit fault, and ignite the instrument and equipment in the small relay.
