Pumping unit thermotetry system is significant to monitor and ensure safe operation of electromechanical equipment. The principle of measuring temperature of the resistance bulb is that, the resistance value will change according to the temperature at measure point. With this resistance value, it can calculate the temperature value. The common faults of the resistance bulb are short circuit and broken circuit. To detect and handle those faults efficiently is an effective guarantee to safe operation of pumping stations.
