We are offering high durability vibrating rod level switch.
protocontrol now offers vibration rod type level switch. This switch is used to detect minimum or maximum level in bins, silos and hoppers filled with any kind of easy flowing solids, e.g. Granules or pellets like grains, granular plastics, foods, etc. The vrls is ideal switch for detecting level of liquids with bulk densities of 20 grams per litre and higher
the electronic circuit when powered excites the stainless steel rod of the probe to vibrate on its resonance frequency. When material covers the rod
of the probe the vibration stops. This is sensed by the electronic circuit which forces its relay to switch. When the rod gets uncovered, the vibration
restarts and the relay switches back.
features:
1) this switch is easy to install
2) requires no calibration
3) no re-adjustment is required as it is unaffected by environmental changes e.g. Temperature, pressure, humidity.
4) no maintenance required as the vibration rod has a self cleaning effect.
5) it is highly durable as contains no moving parts.
6) the rod probe eliminates bridging problem, where material builds a bridge from one rod to the other (in vibrating fork)
7) rod length can be from 150 mm to max 3000 mm.
8) the design is fail-safe design i.e. If power supply fails the relay drops
