Reliable Analog Output for Long-Distance Signal Transmission

A Load Cell 4-20mA is designed for industrial automation and process weighing applications where accurate, stable, and interference-free data transmission is critical. Unlike millivolt output load cells that require signal amplifiers, a 4-20mA load cell integrates a transmitter, providing a standard current loop output compatible with PLCs, SCADA, and data acquisition systems.

At Sensors and Gauges, we supply 4-20mA load cells and transmitters to help Australian industries achieve seamless integration and superior reliability in weighing systems.

Why Choose a Load Cell 4-20mA?

A 4-20mA output load cell offers several key advantages:

• ✅ Long-Distance Signal Transmission – Maintains accuracy over hundreds of meters

• ✅ Noise Resistance – Immune to EMI/RFI interference in harsh industrial environments

• ✅ Direct PLC/SCADA Compatibility – No external amplifier required

• ✅ Standard Current Loop – Widely used in industrial automation

• ✅ Error Detection – Current never falls to zero; faults are easier to identify

How Does a 4-20mA Load Cell Work?

• The strain gauge load cell detects force/weight.

• An integrated signal conditioner converts the millivolt signal into a 4-20mA current loop.

• The output corresponds to weight — for example:

  • 4mA = 0% load

  • 20mA = 100% load

• The signal is transmitted reliably to a PLC, display, or control system.
