Principal of Operation
The Model WC inventory monitoring sensors are third generation smart weight & cable style instruments using a proven technique for measuring the distance from the sensor to the surface of the target material. Unlike most other weight & cable type sensors, the Model WC uses Hall-effect technology to measure the distance/level. This eliminates optical devices that may be susceptible to dust and dirt through normal use or during installation.
In addition, the Model WC utilizes magnetic technology to monitor the descent and ascent of the weight & cable system, allowing intelligent control of the travel and operation of the cable system to ensure reliable operation. The smart sensor control system also self-validates its operation and informs you if any cable system malfunction should occur during measurements.
Application and Use
Model WC inventory monitoring sensors are used to measure the material contents in a vessel based upon the level of the material inferred from a direct distance measurement and the known height of the vessel. The sensor will process its measurement and indicate the value on its LCD display as well as via the sensor’s outputs; MODBUS communication, analog (0/4-20mAdc) and Pulse (transistor and relay types). The distance/level information can be used directly or converted into volume and weight by a receiving device or control system.
The optional Model RCU remote control unit is available to interface with multiple sensors and provide display of distance/level values as well as allowing operator control of the sensors as well. Industries where applications are found include; Plastic Processing, Concrete, Cement, Food, Agriculture, Recycling, Power and more.
