FAQS on 4 wire temperature transmitter

Q: What distinguishes a 4-wire temperature transmitter from 2/3-wire transmitters?

A: 4-wire transmitters use separate pairs for power supply and signal output, eliminating lead resistance errors. 2-wire models combine power/signal paths, while 3-wire adds a reference line for better accuracy than 2-wire systems.

Q: When should I choose a 4-wire temperature transmitter?

A: Opt for 4-wire transmitters in precision-critical applications like laboratory measurements or industrial processes requiring minimal signal distortion. They excel in long-distance installations with high EMI environments.

Q: How does wiring complexity compare between 2/3/4-wire transmitters?

A: 2-wire systems are simplest but least accurate. 3-wire adds a compensation line for improved accuracy. 4-wire offers highest precision with fully separated power/signal circuits, requiring more cabling but fewer calibration needs.

Q: Can 4-wire temperature transmitters work with RTDs and thermocouples?

A: Yes, 4-wire configuration is particularly effective with RTDs (Pt100/Pt1000) for resistance measurement accuracy. While less common with thermocouples, some models support them through specialized input modules.

Q: What are the installation advantages of 4-wire transmitters?

A: 4-wire systems provide superior noise immunity and voltage drop compensation. Separate power/signal paths allow flexible grounding strategies and enable accurate measurements in cable runs exceeding 100 meters.
