Wiring method for temperature sensing cable terminal box
Wiring typically involves connecting the thermocouple sensor to the input terminals of the transmitter, and connecting the loop power supply and receiving device (e., PLC analog input) in series with the output terminals. Refer to the manufacturer's manual for polarity. A temperature transmitter is commonly used to convert the output signal from temperature sensors like RTDs (Resistance Temperature Detectors) or thermocouples into a standard 4–20 mA current signal that can be read by a PLC or control system. This process helps ensure accurate temperature. PT100 is a platinum RTD sensor with 100 ohms resistance at 0°C. Lead wire resistance affects measurement accuracy. Temperature is a physical parameter used to measure the degree of 'hotness' or 'coldness' of any object. At the molecular level.
