Abstract

This paper presents a torque sensor design based on a differential pressure measurement, focusing on thermal stability. The sensor utilizes the principle of measuring the differential volumetric strain due to the applied torque. The proposed design of the sensor is an improvement to the previous design of the sensor. Both the previous design and the improved design are discussed in terms of thermal stability. Comprehensive thermal simulations are conducted on the design in order to compare the thermal stability and performance of the sensors. Based on the presented results it is shown that prosed design of the sensor can achieve at least 99.61% better stability then the previous design. The range of the sensor is +/- 150N.m. Furthermore, it is also concluded that the new design also improves on the manufacturability, ease of integration and overall size of the sensor.
