Frequently Asked Questions

Learn More About 4-20mA Transmitters

A 4-20mA transmitter is usually the better option when the original sensor signal needs to travel further, needs better protection from interference, or needs to be presented in a standardised format for a PLC, controller or monitoring system. Our range is designed for isolating and transmitting current loop signals in challenging industrial settings where signal integrity matters.

Our range includes transmitters for a broad mix of input types, including thermocouple, RTD, current, voltage, millivoltage and potentiometer signals. That makes 4-20mA transmitters a practical choice for applications involving pressure, temperature, flow and level sensing, as well as other analogue measurement tasks.

Yes. Our 4-20mA transmitters are designed for industrial use in environments where electrical noise or voltage surges could otherwise affect signal quality. Isolation, surge protection and industrial-grade design all help support long-term reliability in harsher installations.

Yes. We can help you select the right 4-20mA transmitter based on the sensor type, installation environment and output requirements involved. Whether you need a temperature transmitter, a current or voltage input model, or a solution with strong isolation for a noisy environment, our technical sales team can help you narrow down the right fit.
