When calibrating PRTs against a reference PRT or SPRT, the technical requirements for the readout are the same for the UUTs and the reference. A platinum resistance thermometer (PRT) is a piece of platinum wire which determines the temperature by measuring its electrical resistance. It uses PT100 and PT1000 platinum resistance thermometers (PRTs) and an innovative design to deliver 0.001 °C resolution and 0.015 °C accuracy measurements from –200 °C to +800 °C.

Since the included software is really stable, this type of device is a great tool for great tasks! B = –5.775 E–7 You do not need to reset your password if you login via Athens or an Institutional login. We must solve these problems satisfactorily to provide a proper calibration. A platinum resistance thermometer (PRT) is a thermometer constructed from a high purity platinum element (wire-wound coil or thin film) placed in a tube of metal or glass and sealed with an inert atmosphere and/or mineral insulator. Calibrations are performed using thermometric fixed points to realize the International Temperature Scale of 1990 over the range 83.8058 K to 933.473 K. These realizations offer the chance to discuss realization techniques necessary to maintain reproducibility and stability of the fixed-points. Since PRTs are used in so many different applications, we are presented with a large variety of shapes, sizes, and types. Changing ranges can cause discontinuities in the math fit (the equations are intended to fit platinum, not DMM range offsets or gain errors).

You will only need to do this once. platinum resistance thermometers (SPRTs). Too much source current will result in excessive self-heating and incorrect calibration. I have been using my 4224 PicoScope for years. When accuracy requirements are less severe, PRTs can be used successfully. I really like moving the mouse pointer to a position and having the Time and Voltage display the values at that point. The different resistance values and different sheath materials are intended for different temperature ranges. We have been using Picoscope 6404D for quite some time, and are amazed by its accuracy and powerful emulations while working with numerous signal evaluations. In contrast to previous international scales, the PRT range of the ITS-90 is based on two reference functions, one from 13,8 K to 273,16 K and the other from 273,15 K to 1 234,93 K. The two reference functions were obtained from two real PRTs. This is a concern particularly with dry-wells and furnaces at temperatures above 400°C and with calibration baths that use liquid salt as the bath fluid. Common RTD sensing elements constructed of platinum, copper or nickel have a repeatable resistance versus temperature relationship (R vs T) and operating temperature range. That is, there are minimum requirements for the purity of the platinum wire and the type of construction used.

Click here to close this overlay, or press the "Escape" key on your keyboard. The relative change in resistance (temperature coefficient of resistance) varies only slightly over the useful range of the sensor. A platinum resistance thermometer (PRT) is a thermometer constructed from a high purity platinum element (wire-wound coil or thin film) placed in a tube of metal or glass and sealed with an inert atmosphere and/or mineral insulator. Using a 1 mA sense current will give a signal of only 100 mV. Platinum Resistance Thermometers (PRT) Characteristics. Unlike thermocouples, it is not necessary to use special cables to connect to the sensor. Even an excellent instrument may not perform adequately in a specific application if it is not matched to that application. Unlike thermocouples, it is not necessary to use special cables to connect to the sensor. The temperature range of a platinum resistance thermometer is between 100 ⁰C to 650 ⁰C. So simple to use & beats any other I have ever used hands down. The Platinum Resistance Thermometer Range of the International Temperature Scale of 1990 L. Crovini, H. J. Jung, R. C. Kemp, S. K.
