Level Controls


Series RF Radio Frequency Level Control System

New Series RF Level Control systems employ radio frequency technology to monitor and control the level of almost any free flowing solid or liquid. With no exposed moving parts to become fouled, these unique devices are completely unaffected by material build-up. A NEMA-4X remote control box makes monitoring and wiring changes fast and simple while isolating electronics from potential damage from high temperatures and vibration. All models include a four range time delay, fully adjustable from 0-30 seconds up to 2 hours to prevent false switching under turbulent conditions. Failsafe selection switches enable you to set the default state in the event of a power failure.

Five standard models are offered. Each includes a remote control box with DPDT switch contacts rated for 2.0A @ 110VAC and separate probe assembly. Probes can easily be trimmed to length in the field if required.
