• Why automate temperature sensor calibration?
• Three practical solutions
• How to set them up
• Pros and cons of each one

Why Automate Sensor Calibration?
• Be more productive Reduce the number of repetitive, time-
consuming tasks required for a calibration
Free-up time for other important jobs Temperature Calibration takes time!
• Be confident your results are consistent Time after time No matter who does the work Drift and Out-of-Tolerance conditions
are not operator/test dependent

Three Practical Solutions Automating with a Documenting
Process CalibratorExample: Connecting a 754 to a Dry-Well to test a temperature probe and transmitter; Use DPC track to collect the data
Automating without softwareExample: Connecting 1586A to Dry-Well to calibrate a K-TC Probe; use USB to collect data
Automating with softwareExample: Calibrate K-TC Probes and calculate correction coefficients
• Fluke 754 connected to Fluke dry block using optional communication cable
• Configure test on 754– Source: Dry block– Measure: Transmitter 4-20
mA– Set test points and delay
time• 754 conducts test, stores and
documents results with DPC/TRACK2 software
Solution 1. Automating with 754 Documenting Process Calibrator
Why is a dry-well required?Simulating a TC or RTDAll sensors drift over time.When sourcing temperature from the calibrator, the sensor is disconnected from the transmitter.
The calibrator sources the voltage or the resistance to the transmitter and the sensor is not tested. Without a drywell, the largest source of error (75%) is ignored!
Example: Temperature Loop Calibration• Temperature sensor is removed
from the process but remains connected to the loop and placed in a bath/dry-well for traceability
• Bath or block temperature will be heated or cooled to each calibration point
