Specialty Sensors - Surface
Electric Trace Sensor - Type 1500 and 1500R
TYPE 1500 - Used to accurately measure the surface temperature of any pipe or tank
greater than 3 inches in diameter. The standard X and Y dimensions reduces the heat
sinc effect and greatly improves the accuracy. The 1500 is widely used for electric heat
tracing control for freeze protection and process control, especially where changes in
temperature can cause process material to stratify.

TYPE 1500R - This surface temperature design allows easy removal of the sensor. In
applications where there is heavy insulation on the pipe the sensor can be removed
without disturbing or removing the insulation, reducing replacement downtime and
costs.
