2.3  Sensor Placement (Thermocouple or RTD)

Two wire RTD's should be used only with lead lengths less than 10 feet.

If the temperature probe is to be subjected to corrosive or abrasive conditions, it should
be protected by the appropriate thermowell.  The probe should be positioned to reflect
true process temperature:

In liquid media - the most agitated area
In air - the best circulated area
