The "CAP" Series Capacitance level control is designed for point level monitoring of solids, fluids or slurries in bins, vessels and chutes. The CAP control detects the presence or absence of material by sensing a change in capacitance caused by the difference in dielectric constant of the vessel material and air.

The RT Series rotary level control is designed for point level monitoring of solids in bin, vessels and chutes. The RT eliminates the most common causes of rotary control failure. The de-energizing motor shuts off when material is present, rather then entering a stalled condition. This reduces wear and operating temperature and extends motor life.

This totally non-contacting detector provides high and low point level detection and can see through non-metallic wall build-up to detect the presence or absence of any material. It can be used in pressurized coal down corners; electrostatic precipitator hoppers; fly ash, clinker and coal transfer chutes; and other industrial applications. By sensing the conditions in chutes, it alerts the user of any problems or disruptions in the process. The Ramsey Microwave Plugged Chute Detector is a safe and environment-friendly replacement for nucleonic switches and is not restricted by OSHA or FCC regulations.
