High and High-High Level Detection

The OleumTech® OTC Wireless High Level Switch Transmitter provides two actuation points for detecting high and high-high liquid level conditions. The transmitter can also report transition counts. This top tank mounting transmitter is designed for use with an OleumTech high level switch. The switch is sold separately so that you can select the desired length and choose single or dual actuation option. As a safety measure, regardless of state change, this device reports to the wireless gateway at a user-defined interval. This ultra-lower-power transmitter is powered by a replaceable battery pack that provides up to a 10-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 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 without a local display.
