Sensor Placement (Thermocouple or RTD)
Thermocouple lead resistance should not exceed 300 ohms. If this is exceeded, instrument accuracy could be
affected.
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
