How to calibrate a Pt100 temperature sensor automatically

Beamex MC6-T Multifunction Temperature Calibrator and Communicator: hubs.la/Q01j0-Tm0
Temperature measurement is one of the most common measurements in the process industry and the Pt100 temperature sensors are very common sensors.
Every temperature measurement loop has a temperature sensor as the first component in the loop. So, it all starts with a temperature sensor. The temperature sensor plays a vital role in the accuracy of the whole temperature measurement loop.
The Beamex MC6-T is an extremely versatile portable automated temperature calibration system. It combines a state-of-the-art temperature dry-block with Beamex MC6 multifunction process calibrator and communicator technology.

I'm learning quickly that I cannot do this at home lol.

[@youssefihocine7717]

Thank you you are a great teacher I tell you that I am a metrology engineer, but I benefit from things that were not taught to us at the university

[@BeamexCalibration]

Hi Youssefi, thanks for your kind comments. We are happy to hear that you find these videos useful! It is great to see somebody that is a "metrology engineer", that rocks!!! Keep it up!

[@boucherkordom7452]

Hi, thank you for a very informative video as always. I would just like to know if it is sufficient to calibrate the output of the transmitter only or must we do the calibration for the sensor and transmitter separately?

[@BeamexCalibration]

Hi! That is a very good question. Both methods are being used. So you can calibrate the sensor+transmitter combination, and if that is within accepted tolerance, then it is ok. If there is too big error, then you need to check if the error is from the transmitter or from the sensor. Please check e.g. this video for that kind of case with sensor+tranmitter: kzbin.info/www/bejne/f5-1dGytlsR1rLc In some cases customer do also perform a "whole loop calibration", i.e. they put the sensor into a dry block and then record the final display in the control room. This way all components of the measurement loop gets checked at one calibration. Obviously, if there are too big errors, then each component in the loop needs to be checked. Hope this helps.

Thanks for great info. I am trying to get part number for reference probe.. Cant find one in manual. Any specific part numbers to use?

[@BeamexCalibration]

Hello, the reference probe used in the video is the Beamex RPRT reference probe. It comes in a few different versions: a straight or 90 degree bent one. Also, there is 420 or 660 deg C ranges available. You can find more information and brochure on RPRT probe from the product page here: www.beamex.com/calibrators/beamex-rprt-smart-temperature-probes/ Please note that we also offer an industrial temperature probe model Beamex IPRT. I hope this helps. Thanks, Beamex / Heikki

So, is the corrective adjustment not part of Calibration process ?

[@BeamexCalibration]

Hi Vivek, great question. If we look at the whole process of calibration and all things related to that, the adjustment should also be part of it. We have somewhere mentioned that formally the word "Calibration" is the "documented comparison of DUT and reference", not including adjustments. But if you think at the whole process in the industry, you need to first calibrate the instrument to see if it is still accurate or not. And if it is not accurate, you need to take corrective actions to get it accurate, this can be adjustment or replacement. Also, if the instrument was found to be out of the specifications in the calibration, you need to look back in your process and consider what kind of harm has that caused and is there some action needed (in the worst case even draw products back from the market). I hope this answer, and you can agree on this. Thanks, Beamex / Heikki

what Class is the reference probe? what class is the probe that you calibrate?? how is the reference probe calibrated??

[@BeamexCalibration]

Hi, the reference probe in this video is the Beamex RPRT (www.beamex.com/calibrators/temperature-sensors/) that is a high accuracy reference sensor with up to ±0.007°C stability, when used with the individual coefficients. That reference sensor has been calibrated in out ISO17025 accredited calibration laboratory. The sensor that is being calibrated is a regular lower accuracy industrial sensor. Hope this helps.
