Novel Approach of Non-linearity Analyses of Resistive Temperature Sensors

Abstract

The non-linearity analysis is one of the most important issue when defining the static characteristics of temperature sensors, namely thermoresistive sensors. The purpose of this work is to propose a simple approach based on measuring the signal conditioning parameters to define the model of measured temperature. The developed approach is utilized to obtain a relationship between the bridge parameters and the final measured value of temperature. The data acquisition and signal processing are carried out by Arduino Uno and LabVIEW software.

A Methodology to Measure СP / CV Ratio Using U-shape Acoustic Resonance Tube

“…LabVIEW provides the ability to work with numeric, binary, string data, as well as groups and arrays. In addition, it is possible to output the result in the form of a graph, that is, the construction of graphs of various functions [18].…”

“…Other works [14][15][16][17] illustrate several techniques, based on acoustic measurement that are applicable to measure several physical and chemical parameters such as: density of gases, temperature, displacement and concentration. These methods are based on creating a standing wave within a resonance tube (forced or free resonance mode of operation) and then the physical phenomenon based on acoustic measurement is acquired by a microphone and signal processing is performed using LabVIEW software [16].…”

Pengkondisi Sinyal RTD Presisi pada Terowongan Angin Indonesian Low-Speed Tunnel

“…Dibandingkan dengan hasil kalibrasi pengkondisi sinyal RTD penelitian lain yang menggunakan digital controller E5EK Omron [21] dan Arduino Uno [12] untuk rentang temperatur 20 -50 0 C seperti pada Gambar 13, ketidaklinearan orde 2 (Second-Order Nonlinearity) hasil rancangan ini sangat kecil ditandai dengan nilai koefisien determinasi R 2 = 1. Tingkat linearitas hasil rancangan dan penelitian [12] dapat dikatakan lebih baik daripada penelitian [21].…”

“…Simpangan rata-rata hasil kalibrasi pengkondisi sinyal RTDx01 rancangan jauh lebih kecil dari penelitian [12] yang bernilai 0,72 0 C (2,28%), namun sedikit lebih besar dari penelitian [21] yang bernilai 0,36 0 C (1,17%). Perbandingan hasil kalibrasi penelitian lain [12], [21] ini dapat dilihat pada Tabel II. Terdapat perbedaan hasil pengukuran antara pengkondisi sinyal rancangan RTDx01 terhadap Newport 267B.…”

“…Perlu bantuan sebuah piranti Data Acquisition System Hub (DAS-Hub) yang menjembatani komunikasi Ethernet dengan format BCD paralel pada unit RTD [4]. [11] dan Arduino Uno dengan perangkat lunak LabView dari National Instruments [12]. Beberapa pendekatan rancang bangun pengkondisi sinyal RTD yang lainnya adalah dengan berbasiskan pada sistem Complex Programmable Logic Device (CPLD) dan Field-Programmable Gate Array (FPGA) [13].…”
