Sensor Installation Guidelines

We suggest you mount the sensor at a location in your process or system where

it reads an average temperature. Put the sensor as near as possible to the

material or space you want to control. Air flow past this sensor should be mod-

erate. The sensor should be thermally insulated from the sensor mounting.
