Maintenance of gas pressure switch J120-174 US UE switch spot UE switch in use1．In order to avoid damage to the device, the withstand voltage and maximum temperature cannot exceed the range allowed in the specification, even for a short period of time. In operation, it is allowed to reach the maximum pressure and temperature during start-up and test, but in continuous operation, it must be operated strictly according to the data set by the installation range. Prolonged work at maximum pressure and temperature will reduce the life of the sensor. 2. A spare part is very necessary in harsh environment applications, such as the damage of components may endanger life and property, or the loss of control of high and low limits will cause the system to crash. 3.
