Calculations of the resistance values of 10 ratio resistors

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).

To make further calculations of the thermistor resistance and other parameters, we need to know the resistance values R in each of the measurement channels (from ch_1 to ch_10). The calculations are performed based on the datasets [Maśnicki, R., Tyndzik, K., & Pałczyńska, B. (2021). Determination of the ratio resistors in the input circuits of the NTC10k thermistor calibration system [Data set]. Gdańsk University of Technology. https://doi.org/10.34808/3gjm-h196].

The mentioned measurement results included in the data set 5001.zip, composed of ten files 5001kx.lvm (where: x is from 1 to 10) allows determining the R-value in each channel. They are obtained in the circuit as shown in Figure 2, wherein the place of the thermistor in each of the measurement channels a standard resistor with a resistance of 5001 Ohm was used.

Resistance calculations were performed for ten ratio resistors R, located in 10 measuring channels. The file resR.lvm contains averaged values of ratio resistances in individual 10 channels together with standard deviations.
