    Wireless 4-20mA Temperature Transmitter Monitoring System

ROI-RFX-MA is a simple to use Windows compatible 2.4 GHz RF wireless remote 4-20mA transmitter monitoring system. Using the ROI-RFX-MA allows you to; remotely monitor & record 4-20mA sensor transmitters over distances of up to 1 mile/1.6 km, using industry standard 4-20mA transmitters. Remote sensor measurement or process trend recording is simple; data can be updated real time directly into Excel. Total transmission distance can be extended with additional units, as well as allowing an increased number of sensors.

Monitor 4 sensor transmitters per unit. Multiple units per system, expandable as needed.
