| Feature | 2-Wire Transducer | 4-Wire Transducer |
|---|---|---|
| Wiring Complexity | Simple (fewer wires) | More complex |
| Power & Signal Wires | Shared | Separate |
| Signal Type | Current (4-20mA) | Voltage (0-5V, 0-10V) & Current (4-20mA) |
| Installation Cost | Lower | Higher |
| Noise Immunity | High (current loop) | Lower for voltage outputs |
| Application Type | Industrial process control | High-precision measurement |
Choosing the Right Transducer for Your Application
- If long-distance signal transmission and lower cost are priorities → choose a 2-wire transducer.
- If higher accuracy and separate signal wiring are required → choose a 4-wire transducer.
- If operating in a harsh industrial environment, 4-20mA 2-wire transducers are preferred due to noise immunity.
- If working in laboratory settings or precision applications, 4-wire voltage-output transducers may be a better choice.
