•
Shortened Sensor Cable: To increase the transmitter tem-
perature reading to match the known solution temperature,
decrease the T FACTOR by 3.85 ohms for each
°
C difference.
•
Added Interconnect Cable: To decrease the transmitter tem-
perature reading to match the known solution temperature,
increase the T FACTOR by 3.85 ohms for each
°
C difference.
Example:
Suppose the known solution temperature is 50
°
C
and the transmitter reads 53
°
C due to interconnect cable re-
sistance. Multiply the 3
°
C difference by 3.85 ohms to get 11.55.
Then increase the sensor T FACTOR by adding 11.55 to it and
entering that value. If, due to a shortened sensor cable, the
transmitter was reading 3
°
C less than the known solution tem-
perature you would decrease the sensor T FACTOR by
subtracting 11.55 from it.
*Sensors with a Pt 100 temperature element provide inherently less
accurate temperature readings and are not recommended.
