Eddy-current rail displacement sensors are used for confirming rail displacement. However, collision with gravel and snow due to the short distance between rail head surface and sensor causes failures or malfunctions. Therefore, it is necessary to increase the distance from the rail head surface to the eddy-current rail displacement sensor. In this paper, the use of triangle spiral coils make rail displacement detection possible from the rail head surface, which is twice that of the conventional eddy-current rail displacement sensor up to a distance to the sensor.

Compared with electromagnetic current transducer and electronic current transducer, fiber optic current transducer (FOCT) represents the developing direction of current transducer, which has a series of advantages, such as wide bandwidth, good insulation performance, high measuring accuracy, and so on. FOCT is one kind of new-type precise sensor based on the principle of Faraday magneto-optical phase circling, its' complicated structure results in shot noise, intensity noise, hot phase noise, and electromagnetic interference noise, which have great effect on FOCT's performance. Relativity of noise random process in time domain and stability of noise random process in frequency domain are analyzed, based on the analysis results, noise identification model and algorithm are proposed, and different type noise in FOCT showing main character is quantified by using noise identification model and algorithm. Aiming on decreasing the influence of noise to FOCT performance, filtering algorithm is applied in FOCT data processing. Experiments show that noise character is complex, noise dentification model and noise filtering algorithm are effective in FOCT noise processing system.

In order to obtain the transformation model between the three output signals of the contact probe of the Micro/nano coordinate measuring machine (CMM) and the three-dimensional space coordinates of the probe ball, a calibration model based on Taylor expansion is proposed. The probe consists of a 3-DOF coaxial beam sensor with the displacement measurement based on the principle of Michelson interference and two angles measurement based on the autocollimation principle, a suspension mechanism and a ruby ball. According to the relationship between the coordinate vector of the ball centre and the output signal vector of the probe, the calibration model based on Taylor expansion is proposed. The reliability of the model is verified by experiment tests. Performance tests show that the maximum calibration error of the model is 92 nm. The results demonstrate the calibration model features the feasibility and the validity, which can meet the calibration requirement of the Micro/nano CMM.

The study focused on application of spectral permittivity technique subjected to wide frequency range of from microwaves to millimeter waves (i.e. 0.5-50 GHz) at the temperature of 60°C to understand the relationship of dielectric permittivity and fatty acid composition in fats and oil. Results showed that the dielectric constant of 4 animal fats and 2 vegetable oil exhibited same frequency dependence. The dielectric constant of fats and oil increases with an increase in the degree of unsaturation in vegetable oil at 7.4, 13.4, 18.3, 23.3, and 46.0 GHz. The dielectric constant decreases with the increase of composition of palmitic and oleic acid in animal fat at 13.4 and 18.3 GHz respectively. The understanding obtained in this work could be useful towards distinguishing fats and oils especially lard using rapid permittivity spectroscopy based on accurate chemical composition, suitable for Halal product analysis.

Poly(vinylidene fluoride) (PVDF) is one of the ideal materials for wearable pressure sensing owing to its excellent piezoelectric property, good flexibility, and easy fabrication processing. In this work, we mixed PVDF matrix with silicon carbide (SiC) nanowires acting as an efficient nucleating agent to transform the non-polar α phase to polar β and γ phases to improve the crystallinity of electroactive phases and enhance the piezoelectricity of PVDF thin film.

The simple and fast liquid inspection method using step response in electromagnetic sensor is presented. When the liquid sample is set inside the cylindrical electromagnetic sensor, the impedance profile of the sensor changes in accordance with the electromagnetic properties of the liquid. First of all, the theoretical background is explained with a simple RLC circuit analysis. To provide a simple and fast measurement, this paper focuses on both the maximum value of the voltage and the time constant. An experimental demonstration of liquid inspection is also presented.

Aiming at the problems of fault diagnosis for rotating machinery, this paper proposed a fault diagnosis method combining minimum entropy deconvolution (MED) with fruit fly optimization algorithm (FOA). In the MED method, the objective function method (OFM) is used to find the set of filter coefficients under the condition of maximal kurtosis. Given that the filter coefficients obtained by OFM are local optima not global optima and MED is difficult in parameter selection, FOA is applied instead. A filtered signal is obtained by FOA and MED, and envelope demodulation is carried on it for fault diagnosis. Results from rolling bearing fault simulation experimental system show that the proposed method has better noise reduction performance and is able to extract fault features of rolling bearings, and it is better adapted to engineering applications as compared with prior MED method.

A simple voltammetric two-electrode ion sensing system has been developed and utilized for pH value detection. In this system, active carbon (AC) electrode with constant electrode potential and good electrical conductivity is employed as the counter electrode. A solid contact voltammetric ion selective electrode (VISE), prepared by drop coating a layer of voltammetric ion selective membrane on a glassy carbon electrode, acts as the working electrode. Via cyclic voltammetry, the reduction peaks of the cyclic voltammograms are collected for quantification purposes. pH values have been detected by this system, using a voltammetric H+-selective working electrode. Furthermore, the results show a good linearity (r = 0.998) and precision (RSD = 1.05 %) which are comparable with those of conventional three-electrode system. This two-electrode system proposed here allows for quantification of pH values in complex samples (e.g. tap water and coffee solution). The detection results obtained here were in good agreement with the values detected by commercial glass pH meter.

This research reports a high frequency lateral-field-excited quartz crystal resonator sensor (LFE-QCR) arranging the two excitation electrodes on one side. It is well known that when used in liquid LFE QCR could detect both mechanical and electrical property[1]. However, the mechanism and exact relationship between the liquid permittivity and the frequency shift is not clear. In this paper, two LFE-QCR chips with different but both highly fundamental frequency are used to investigate the frequency dependence of LFE-QCR on liquid permittivity. And in order to observe the real-time change of frequency, a flow-injection-based system is established, which consist of a syringe pump, a sample injector, and a custom-made micro-flow cell. Sensitivity of LFE-QCR for permittivity has been confirmed by using different concentrations of 2-propanol. In addition, according to the reliable experiment data, we present an approximate relationship between frequency shift and permittivity.

Loss of life of the workers inside manhole is a common problem for many parts of the world. To resolve this issue a portable, low cost, simple manhole gas detection unit has been designed and developed which is capable to detect the poisonous gases like carbon monoxide, hydrogen sulfide, and explosive gas like methane within a minute and raise alarm if the concentration of any gas is beyond the threshold limit. Commercially available sensors were found sensitive, but less selective towards its target gases. To improve the selectivity, the authors have developed ZnO based sensing materials for detecting selectively methane, carbon monoxide and hydrogen sulfide from a mixture of gases. The materials were found highly sensitive and selective towards its target gases at either room temperature or at low operating temperature around 100°C. Different surface activation processes like plasma treatment, composite materials were used to enhance the selectivity of the sensing materials.
