Side-Mountable Solution

The OleumTech® “HL2” High Level Switch Transmitter is a side tank mounting solution for detecting high liquid level conditions. The HL2 Transmitter can also report transition counts. The HL2 includes the side mountable switch and float, making it a complete ready-to-deploy solution. The HL2 utilizes on-delay exception reporting method and users can set the debounce filter ranging from 20 ms to 2000 ms to control just when the high level detection occurs. As a safety measure, regardless of state change, this device reports to the wireless gateway every five minutes. This ultra-low-power transmitter is powered by a replaceable battery pack that provides up to a 7-year life. The push button LCD interface allows for device configuration and instant access to process data.

Reliable, Scalable and Safe

The field-proven wireless sensor node 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 without a local display.
