Stop tying up your expensive process meters.

When you need to simulate multiple transmitters at once—like level, flow, and pressure—to properly test your PLC logic and SCADA, tying up a stack of premium multimeters just isn't practical.

Flucx is the relatively cheap dedicated loop sink built to solve this. It’s affordable enough that you can populate an entire multi-point development panel, yet rugged and reliable enough to leave hardwired in for weeks of long-term continuous testing. Get the precise 4-20mA control you need, without bottlenecking your primary test gear.


Effortlessly simulate any 4-20mA process transmitter.

Get smooth, precise analog control from 4.00mA up to 20.00mA with a high-resolution 0.1mA digital readout.

Once you find your exact setpoint, simply press the aluminum knob down to save it. If loop power drops, flucx automatically restores your exact current setting the second power returns—preventing unexpected spikes in your process logic.
