The WIO® High Level Switches are specifically designed for industrial liquid level sensing for spill/overflow prevention.
The High Level Switches are self-contained and integrated with a battery-powered RF transmitter which immediately transmits wireless alarms when a set point level is reached. These industrial wireless automation switches are to be used with WIO® Wireless Gateway / RTU products which connect to the primary control panel or RTU. The WIO System forms the foundation of wireless process control enabling automatic emergency shut-down of the dispensing pump.
Top mount versions come in wide range of options, up to 15 feet maximum probe length, and 1-or 2-stage switching. This versatility enables customizable actuation points of two separate specific gravity liquids, as in the case of sensing water in a gasoline or oil tank. The dual input High Level Switch is specifically designed to provide two alarms for added protection against over fills. Typically, one float is required for each point at which you need a switch action to occur.
The WIO® High Level Switches utilize a license free 902-928 MHz ISM bandwidth FHSS technology to reliably transmit wireless alarms. This eliminates installation costs of cable and conduit runs. With the WIO® High Level Switches, installation time is now measured in minutes, not days or weeks.
