Vibrating Point Level Sensor with Self-Diagnostics

June 24, 2014

The SC35 series vibrating fork point level sensor uses state-of-the-art piezoelectric crystal and electronic technology, does not require any calibration, and can diagnose potential problems, including material build-up and abrasion to the primary sensing elements.

The vibrating fork point level sensor can be used to detect the presence and absence of bulk solid material over a wide range of material densities. The minimum density that the SC35 series can detect is 0.624 lb/cu ft. Other features of the level sensor include self-diagnostics, a small compact housing, universal 19-253VAC/VDC power supply, and the availability of standard, pipe extended, high-temperature, and cable-extended probe versions.

The SC35 series utilizes piezoelectric crystal and solid state electronics technologies to produce vibration in the tuning fork element at a specific frequency and receive electronic feedback. When the probe element is covered or in contact with the target material the vibration is dampened, the electronic feedback changes and presence of the material is thereby sensed by the electronics, which changes the state-of-the-sensor output to indicate material presence. When the probe element is again free of the target material the vibration again is produced, the output state reverts to indicate material absence.
