Calibration of a Platinum Resistance Thermometer (Pt-100) and Its Measurement Uncertainty Analysis

Abstract

A common problem found in the industrial metrology is the reliability of the results obtained from temperature instruments, especially when they are used in operational processes which effect to the production quality. In this case, calibration of thermometer associated with a national standard through a documented unbroken chain of calibrations is of vital importance. This study presents the reliability of a Pt-100 Platinum Resistance Thermometer (PRT) measurement results which can be described according to calibration and statistical methods. The calibrated PRT's resistance values are characterized as around 131.00 Ω by making a comparison with a reference PRT at 80 °C bath temperature and the total uncertainty of the calibration temperature is determined as ±0.08656 °C by metrological traceability together with measurement uncertainty. The total uncertainty value changes depending on uncertainty values of each equipment used in the calibration system.

Calibration of Digital Thermometer using Sensor and Indicator Method

“…The method used for calibration of digital thermometer is the working method of sensor plus indicator which is sultry to the quality document MK-12.01 with the title calibration method -Sensor Plus indicator referring to JIS document Z8710:1993, Temperature Measurement -General Requirement and Guide to The Expression of Uncertainty in Measurement, ISO/IEC Guide 98-3:2008 (E) [10,11]. The standard used is the sensor PT 100 [3] and indicator with the brand Omega (PT100) and Additel (indicator). Calibration is done in environmental conditions 25 ± 3 ºC for room temperature and 55 ± 10% RH for room humidity.…”

Pemetaan Suhu Chiller Penyimpanan Produk Rantai Dingin Pada Salah Satu PBF (Pedagang Besar Farmasi) di Jakarta

“…Validasi sehu penyimpanan pun menegaskan bahwa prosedur yang dilakukan telah tepat dan berada di bawah kendali validasi yang memadai. Validasi suhu penyimpanan digunakan untuk memastikan bahwa suhu selama proses penyimpanan tidak menyimpang dari ketentuan [23,24]. Mapping suhu bertujuan untuk mengetahui fluktuasi atau perubahan suhu yang terjadi pada chiller selama penyimpanan serta untuk mengetahui bahwa suhu penyimpanan sesuai dengan suhu yang dipersyaratkan untuk penyimpanan CCP sehingga kualitas, stabilitas dan efikasi sediaan terjamin.…”

Implementation of proportional–integral control in Baglog steamer temperature control

“…Hence the name begins with "PT." Called PT100 because this sensor was calibrated at 0 °C at a resistance value of 100 ohms [20]. Temperature calibration in the form of PT100 can use the method of comparison of measurement results on PT100 with a thermometer.…”
