The transmitter is intended to monitor the temperature of bearings and other mechanical devices to protect against mechanical destruction and or fire.

Various sensing probes are available. Lug style may be placed on the outside case for rotating shaft bearings or gearboxes. Probe type may be placed in a drilled hole for fixed shaft style bearings. For probe type, the temperature sensor is in the tip of the probe. These transmitters are auto selecting for either Ringline 128 or Ringline 192.

Most lubricants break down when they are above 90 degrees Celsius. By continuously monitoring and trending temperature values, the user may detect problems before there is a mechanical collapse. The user should always check the operating temperature range of their lubricants from their lubricant manufacturer.
