The Model PZP vibrating point level sensor is capable of detecting bulk solid materials with a density as light as 1.0 to 1.5 pcf (pounds per cubic foot) and up to 100 pcf. In addition, the PZP does not require calibration and uses a unique diamond shape single element that, unlike traditional tuning forks, is immune to material packing and bridging. The sensor uses dual piezoquartz crystals that respond to electrical excitation by vibrating, which results in the vibration of the sensing element at about 280 Hz. The uniqueness of the PZP’s diamond-shape sensing element and electronics provides the sensitivity to detect very lightweight materials in addition to heavier materials. This ultralightweight sensing capability makes this level sensor well-suited to dust-collection applications.
