Strain gage sensitivity depends on the material from which it is made. It usually ranges from 2 to 4 for many metal alloys. When using strain gages, it is necessary to observe which metal one wishes to deform, and then choose a strain gage with an alloy that responds to a temperature similar to that of the metal involved, in order to minimize errors.

In this study, a strain gage was used with a standard resistance of ohms and temperature compensation compatible with the shaft material. Therefore, for a shaft with a solid cross-section with a d diameter, torque can be determined using Eq. From Eqs. In order to make it easier to process the signal obtained by the strain gage, resistance is converted to voltage through the Wheatstone bridge in the transduction electronics circuit. An alternating current signal feeding a Wheatstone bridge and a synchronous demodulator are presented by "Analog Devices" for solution with strain gage circuits Gerstenhaber and Lee, Figure 4 shows a simplified diagram of this circuit.

ZigBee was chosen due to its viability for on-board applications, which require low energy consumption.

This module can be configured using X-CTU software, which allows writing and modifying firmware as required by the application. Software was used to program the Xbee to send a reading through a package during a 1 ms sampling period, and the analogical input was enabled. An interface board was made for the Xbee to ensure reference voltage and a 3V feed using two LTES regulators, according to the circuit in Fig. The board layout and the capacitors used were designed to minimize the noise, which is part of the voltage regulation process.

The remote unit set strain gage - transduction electronics - FNTM is comprised of sensitive integrated circuits technology. Due to the sensitivity to the weather and the rotation of the reducer shaft, GPICEEMA developed a clamp with a flexible fiberglass sealant for protection and fixation of this circuit, designed in such a way that its measurement acquisition will not be influenced Author, The clamp shown in Fig.

In designing the system, it is very important to verify the limit or range of use of the components regarding the magnitude at which work is done. For the telemetric system proposed by this study, it is necessary to size the devices appropriately, maximizing their work life and minimizing the acquisition errors. Since the strain gage is to be used to measure torsion in a shaft submitted to angular acceleration, a few precautions must be taken about its dynamic behavior.

It is necessary to establish a maximum frequency of use of the strain gage so that the response time is compatible with shaft rotation.

Therefore, the time of action of the strain gage is sufficiently compatible with the dynamic response for most applications. Another point that should be looked at is the maximum torque that can be borne by the strain gage. Using the solid mechanics theory, it is calculated that this strain gage can work with torques of up to 2,, in. Another limit that must be taken into account is the value which will be caused by electronic transduction saturation.

Based on Eq. Therefore, it is concluded that the circuit will never be saturated, since the maximum deformation of the strain gage is well below the value subject to electronic saturation. Due to the low consumption of the electronic components present in the remote unit, it is estimated that the total voltage drained is on the order of 50 mA.

Considering that the super battery consumption is 19 A. In order to monitor torque in a mechanical pumping unit used to extract oil, each acquisition will last ten seconds at minute intervals. In this case the system can be run autonomously for approximately 4 years. Analysis of the Results. The commercially available dynamic torque meters are calibrated by static torque Fujii et al.
