Side-Mount High Level Switch Included

The OleumTech® Wireless High Level Switch Transmitter is a side tank mounting solution for detecting high liquid level conditions. It can also report transition counts. The SM-HLS includes the side mountable switch and float with a welded 2-inch NPT adapter, making it a complete ready-to-deploy solution. The device utilizes an on-delay exception reporting method allowing users to set the debounce filter ranging from 20 ms to 2000 ms to help remove undesired state reporting due to signal noise or hysteresis. As a safety measure, regardless of state change, this device reports to the wireless gateway at a user-defined interval. This ultra-low-power transmitter is powered by a replaceable battery pack that provides up to a 10-year life.

Reliable, Scalable and Safe

The field-proven wireless transmitter communicates with an assigned wireless gateway within the OTC Wireless Sensor and I/O Network creating a highly scalable network, accommodating virtually any I/O requirement.

The OleumTech wireless transmitter is certified for use in Class I, Division 1 (Zone 0) hazardous locations. It is intrinsically safe, designed not to cause a spark, and can be serviced without being removed from a process.

This product is also available with a local display.
