4B Components Ltd. designed an extended power shield for the Auto-Set™ series of RF capacitance point level indicators for use with bulk granular solids, powders and liquids. The power shield creates a barrier and enables the unit to ignore material built up on the probe, preventing false readings. The Auto-Set™ is now available in three standard power shield lengths of 4, 12 and 16 inches. Installation through thick concrete silos is easier since only a one inch diameter hole is needed for probe insertion. The Auto-Set™ also provides the user with visual indication of the set values which allows for simpler on site adjustment and set up via a push button membrane and large LED display.
