Level and Choke Switches
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.
