Plumb-bob level system available with stronger, cleaner stainless tape

February 16, 2009
The plumb-bob unit for silo level measurement is the only weight and cable device that uses a stainless steel tape in place of the braided polyester or steel rope/cable offered by others. Advantages include a higher tensile strength, superior tape cleaning to remove build-up, low-maintenance pulley system, and the ability to provide solid/liquid interface measurements. Core features are separate electronic and mechanical housings, relay, analog, and digital outputs, and FM/CSA approvals for hazardous areas.
