Calibration of NTC 10k thermistors in temperature of 50 C

Description

The presented data set is part of the research aimed at determining the actual characteristics of each thermistor in a package of twenty NTC10k type sensors.

The measurement system is shown in Fig. 1. A measurement system based on NI PXIe-1082Q (National Instruments Chassis), equipped with NI PXIe-8135 (Embedded Controller), NI PXIe-6341 (DAQ card) and NI SCB-68A (68-pin connector block), was used for the acquisition of measurement data. Eleven input channels of the DAQ card were used in the measurements. Channel 0 (ch_0) was used to measure the supply voltage. Sensors numbered 1 to 20 were tested in two parts, ten sensors per set. They were connected to the inputs of channels 1-10 (ch_1-ch_10) of the DAQ card.

The conditioning unit for individual sensors is shown in Fig.2. These circuits are performed on connector block SCB-68A as the voltage dividers. For the set of ten thermistors, the supply voltage is measured in channel 0 (ch_0) of the DAQ card, and individual thermistors are connected to channels 1-10 (ch_i).

The thermistor set was placed in the T-704 thermocalibrator chamber at 50°C (confirmed by a digital temperature gauge DT-34 with an accuracy of 0.1°C).

The folder I50,0C  composed of 15 files 50,0Cx.lvm (where: x is from 0 to 14), contains the measurement results of supply voltage Uz (ch_0) (Fig.2) and voltages at the outputs of ten voltage dividers (ch_1 to ch_10), repeated in a series of 30 measurements for all 11 channels.

The measuring series was carried out also for the second package of ten thermistors. The folder was marked as II50,0C, containing the files II50,0Cx.lvm  (where: x is from 0 to 14).
