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.
