Level Indicators & Plug Detectors
4B offer a variety of level indicators to detect high / low levels of bulk granular material in bins, tanks and silos. The range includes capacitance point level indicators, rotary paddle switches and capacitance proxy level / plug detectors. 4B level sensors can be connected to a PLC or to one of 4B’s hazard monitoring systems to provide alarm and/or shutdown of your machinery.
- Capacitance probe; detects the presence or absence of liquids and free flowing bulk granular materials and powders such as grain, feeds, seeds and chemicals
- Application: level indicators (tanks / silos); choke switches (chutes, conveyors, elevator legs)
- Detects presence or absence of liquids & free-flowing bulk granular materials
- Easy installation & self-containing
