“…The proposed technique can be popularized to other applications of remote measurement using resistive sensors with lead wires such as resistive displacement sensors, magnetic field sensors, piezoresistive sensors, etc. For example, the strain gauge described in Reference [22] and the flow sensor mentioned in Reference [23] both need to eliminate the errors caused by lead wire resistance through four-wire configurations. So that these sensors are able to turn into two-wire system from three-or four-wire system, saving significant cost of lead wire and time for construction.…”

In remote measurement systems, the lead wire resistance of the resistance sensor will produce a large measurement error. In order to ensure the accuracy of remote measurement, a novel lead-wire-resistance compensation technique is proposed, which is suitable for a two-wire resistance temperature detector. By connecting a zener diode in parallel with the resistance temperature detector (RTD) and an interface circuit specially designed for it, the lead-wire-resistance value can be accurately measured by virtue of the constant voltage characteristic of the zener diode when reverse breakdown occurs, and compensation can thereby be made when calculating the resistance of RTD. Through simulation verification and practical circuit testing, when the sensor resistance is in 848–2120 Ω scope and the lead wire resistance is less than 50 Ω, the proposed technology can ensure the measuring error of the sensor resistance within ±1 Ω and the temperature measurement error within ±0.3 °C for RTDs performing 1000 Ω at 0 °C. Therefore, this method is able to accurately compensate the measurement error caused by the lead wire resistance in two-wire RTDsand is suitable for most applications.

Measurement of strain and stress plays a crucial role in advancing research in mechanical engineering. In this paper, the bending strain and stress of the steel cantilever beam subjected to concentrated loads at the free end are investigated using analytical, experimental, and numerical approaches. The experimental investigation was carried out through the use of a strain gauge sensor connected with a Wheatstone quarter-bridge configuration. The strain gauge used in this experiment is interfaced with the NI SignalExpress software in conjunction with the NI modules to ensure accurate data acquisition. The experimental measurements provide essential benchmark values for comparison with the numerical results. The numerical simulation is developed using ANSYS Workbench. The comparison results show that the experimental values have good agreement with the simulated FEM and analytical values. The findings of this study provide valuable insights into the bending strain characteristics of steel cantilever beams and contribute to the advancement of mechanical engineering research.
