Presented is an inherently-robust wireless capacitive MEMS temperature sensor capable of operating to 300??C. The heart of the sensor is an array of bimorph (metal-dielectric) cantilevers whose deflections are sensed by an array of appropriately placed electrodes. The key advantages of this configuration are the following. First, its dielectric layer is SiO2 thermally-grown at 1,100??C as opposed...
This paper presents a prototype of a wireless temperature and/or pressure sensor designed for operation inside a thermal insulating double-walled steel vessel. This is achieved by means of a passive (semi-active) radio frequency identification (RFID) transponder which obtains the energy required for its operation from a super low frequency (SLF) external field. The measured temperature and/or pressure...
This paper presents a wireless rotor temperature measurement system based on MSP430 monolithic processor and nRF401 wireless communication module. Hardware structure, function of main devices and software design are also introduced. Service condition indicates that this system is simple and easy-to-use and the temperature signal is stable and reliable. When temperature measurement of 10 points above...
Currently, a pulsed high magnetic field facility (one of national main science and technology infrastructures) is being built in china. with the need of the construction of this facility, a magnetic field measurement system applying point coil as a sensor was developed. A digital integrator is used to restore the waveform of magnetic field. The principle of measurement and configuration of this system...
As a basic scientific experiment platform, the pulsed high magnetic field has attracted more and more attentions recently. In this paper, we introduced the principle of magnetization measurement in pulsed high magnetic field, the fabrication of the magnetization holder and its compensation circuit used in the measuring system. Meanwhile, the magnetization characters of Nd0.7Ca0.2Sr0.1MnO3 are measured...
This paper provides the ingredients for an architectural discussion concerning industrial contactless pick-and-place (P&P) multiple robot design, which incorporates a direct-drive linear permanent magnet motor for the long-stroke movement in a multiple robot component mounter machine. Especially, direct-drive linear permanent magnet motor selection, contactless data and energy transfer and thermodynamics...
