Capacitance probes detect the presence or absence of material in contact with the probe by sensing very small changes (as low as 0.5 pF) in capacitance caused by the difference in the dielectric constant of the material versus the air.
Capacitance probes are point level indicators, used mainly for high or low level detection in bins, tanks or silos.
BinMaster capacitance probes aim to provide fail-safe, interference-free operation with quickset calibration functionality.
The probes work below the radio frequency level of 9 kHz, at 6 kHz, to prevent interference with two-way radios or other equipment operating in the radio spectrum.
In addition, the probes are seen as an affordable, flexible solution for level detection in bins, tanks or silos.
The probes aim to perform accurately even in dusty, sticky or clinging materials. Class II hazardous location ratings and an assortment of extensions can be custom-built according to specific requirements, making the point-level sensors suitable for a variety of solid, liquid and slurry materials.
The range of products available include capacitance probes and accessories for the following applications:
- High- and low-level detection in containers used for material storage or process manufacturing
- Hazardous locations
- Sanitary applications for food and dairy processing
- Space-constrained areas or applications where material flow or bridging may damage a standard probe
- Auto-calibration probes for automatic calibration without having to remove the unit cover
- Remote electronics in a housing separate from the probe, suitable for high temperature, high vibration, or hazardous environments
- Compact capacitance probe for use in tight spaces
- Bendable probe designed to fit in tight spaces or in vessels where obstructions prevent the installation of a straight probe
- Point-level alarm panel for monitoring and alerting to high and low status for two to 12 separate vessels
- Heavy duty capacitance probe for high- or low-level detection in heavy materials
- Flexible cable extension probe for high-, mid-, or low-level detection when it is necessary to top mount the sensor or in lump materials that might damage a rigid probe
