This paper presents an experimental comparative analysis of a torque measurement method based on volumetric strain, utilizing a prototype torque sensor design is compared to a reference high performance torque sensor. A brief description of the background work of the numerical analysis of the method is also discussed as well as the readout electronics design. Based on the simulations and readout electronics...
This paper proposes a torque measurement method based on volumetric strain. A model of the measurement system based on the differential pressure monitoring is proposed and theoretically discussed. The error sources are identified and an error propagation model is presented for the proposed torque measurement method. Considering these error sources, a prototype torque sensor is presented as a case...
This paper focuses on the thermal stability of a high performance, low-range calibration setup for differential air pressure sensors. The setup is a dual parallel chamber design with the full range of ±320 Pa, which can be translated to a temperature mismatch of only about 0.93°C between the chambers. Due to the limitations of existing temperature measurement technology, we propose a finite element...
Low range differential air pressure sensors are used widely in various applications. In this paper the effects of temperature change on transient behavior of the calibration setup for differential air pressure sensors, due to temperature gradient are analyzed. A high performance reference setup utilizing ideal gas law, for differential air pressure sensors, is selected for experimental analysis. The...
Nanocomposites reinforced with hybrid fillers of carbon nanotube (CNT) and carbon black (CB) were developed, aiming at enhancing the electrical conductivity of the composites with balanced mechanical properties while lowing the cost of the final product. Epoxy-based nanocomposites were successfully prepared with varying combinations of CNT and CB as conductive fillers and their electrical and mechanical...
