Level-Probe - Orion Capacitive Level Probe , Capacitive Level switch
ORION LS Capacitive base level switch for Bulk and liquid materials:

Capacitance level detectors are also referred to as radio frequency (RF) or admittance level sensors. They operate in the low MHz radio frequency range, measuring admittance of an alternating current (ac) circuit that varies with level.The electronic circuitry of the probe performs the functions of: 1) rectifying and filtering the incoming power, 2) generating the radio frequency signal, 3) measuring the changes in current flow, and 4) driving and controlling relay interface. The circuitry is usually of solid state design and provided with potentiometer adjustments for setting sensitivity.

Accuracy (including linearity, hysteresis, and repeatability, but excluding temperature and supply voltage effects) is typically 0.25% of range. Minimum span is 4 pF, and the upper range limit (URL) is 2,500 pF.

Level switches are usually provided with constant time delays for filtering out false readings caused by material shifts or splashing liquids.

Installation Considerations :
The capacitance probe should be mounted in such a way that its operation is unaffected by incoming or outgoing material flow. Material impacts can cause false readings or damage to the probe. When measuring low-dielectric materials, it's important that the entire probe be covered, not just the tip.

Install the probe so that it does not contact the vessel wall or any structural elements of the vessel. The probe should not be mounted where material can form a bridge between the active probe and the vessel wall. In addition, the probe should not be mounted at an upward angle, to avoid material build-up.

If more than one capacitance level sensor is mounted in the vessel, a minimum distance of 100cm. should be provided between the probes. Closer than that and their electromagnetic fields might interfere. If a capacitance probe is installed through the side wall of a vessel and the weight of the process material acting on the probe is sometimes excessive, a protective baffle should be installed above the sensor.
