The TA Series dual output temperature sensors have an output
sensitivity of 10 mV/deg C. Occasionally the user would like to measure the
temperature in degrees F. This requires compensation for the 32 degree
offset between scales. ( F = 1.8C + 32 )
If setting the sensitivity in degrees F, enter 5.55556 mV/deg F as the
engineering unit. The output value of the data collector will be in degrees F,
and the user must add 177 mV dc offset (32 degrees) to the output voltage
of the sensor to get the correct temperature value.
EXAMPLE: Output voltage of TA Series temperature sensor is 500 mV
(output voltage + offset voltage) / engineering unit = degrees F
(500 mV + 177 mV) / (5.55556 mV/deg F) = 122 deg F
