Easy-mount level sensors
Cyclonaire Corporation released a compact line of level sensors that provide many mounting and probe options for new and retrofit applications. The modular design of the sensor probes allows flexibility in providing customized capacitance sensors to meet a variety of customer needs. When integrated with Cyclonaire controls, the sensors can reportedly start or stop conveying systems and other machinery instantly at the point where product reaches a specified level. They can also indicate whether or not product is flowing freely.
Cyclonaire CycloLevel Sensors read the presence or absence of material in contact with the sensor probe by monitoring changes in the capacitance caused by the difference in the dielectric constant of the vessel material and air. The sensors operate at approximately 6 KHz, well below the RF level. Because they operate at very low current and frequency, they will not interfere with nearby electronic plant equipment and are not susceptible to interference from other electronic devices.
Cyclonaire CycloLevel Sensors are ideally designed for high-level and low-level detection in powders and bulk solids. Mounting accessories allow CycloLevel units to be used with almost any shape or type of bin, silo, tank, hopper, chute, or other vessel where material is moved, stored, or processed. All wetted parts are 316 stainless steel. A variety of probe styles is available for the sensors, ranging from flexible cable probes for aggregate to 3-A/USDA-compliant probes that are food-grade safe.
Cyclonaire sensors incorporate a feature that forces the sensors’ active signal to monitor a large area around the probe to guard against false readings caused by the buildup of material on probe surfaces or by bridging between the probe and vessel sidewall. Time-delayed readings minimize false signals from sudden material shifts. A high/low fail-safe switch eliminates process accidents caused by power failure, and a bright external LED status light on the sensor top indicates whether the probe is covered, uncovered, or in a failed condition.
