“…Before coated with Ni, the resistivity of substrate Cu = (1,19  0,08)  10 -3 /sq and after coated with Ni the sheet resistivity of all Cu/Ni samples become increase greater than sheet resistivity of Cu substrate. This is in accordance with Afsarimanesh's expression that one of methods to increase Cu resistance is combining it with other materials to form alloys [9]. According to the Hume-Rothery formula if two materials have the atoms with nearly the same size, having a relative atomic size difference that less than 15%, having the same crystal structure, and the having an almost identical electronegativities, the two materials are easier to form the alloy because its are possible to diffuse substitutionally.…”

Abstract. In this research, it has been made Cu/Ni thin film produced with electroplating technique. The deposition process was done in the plating bath using Cu and Ni as cathode and anode respectively. The electrolyte solution was made from the mixture of HBrO3 (7.5g), NiSO4 (100g), NiCl2 (15g), and aquadest (250 ml). Electrolyte temperature was varied from 40C up to 80C, to make the Ni ions in the solution easy to move to Cu cathode. The deposition was done during 2 minutes on the potential of 1.5 volt. Many characterizations were done including the thickness of Ni film, microstructure, and sheet resistivity. The results showed that at all samples Ni had attacked on the Cu substrate to form Cu/Ni. The raising of electrolyte temperature affected the increasing of Ni thickness that is the Ni thickness increase with the increasing electrolyte temperature. From the EDS spectrum, it can be informed that samples already contain Ni and Cu elements and NiO and CuO compounds. Addition element and compound are found for sample Cu/Ni resulted from 70 electrolyte temperature of Ni deposition, that are Pt and PtO2. From XRD pattern, there are several phases which have crystal structure i.e. Cu, Ni, and NiO, while CuO and PtO2 have amorphous structure. The sheet resistivity linearly decreases with the increasing electrolyte temperature. IntroductionIn the husbandry industry, the existence of low-temperature thermometers is needed especially on the breeding using artificial insemination (IB). For the purposes of IB to obtain the qualified cow sperm the government is still importing. During delivery and storage, the sperm is placed in a special flask containing liquid nitrogen with the temperature of -198C. As a part of the design of flask, there is a hole for liquid nitrogen to evaporate out to avoid the explosion. The problem is if the evaporation occurs continuously then the nitrogen content in the flask becomes less and the temperature increase. If the temperature inside the flask reaches the critical temperature i.e. -100C then the cow sperm will die. Therefore, a low-temperature thermometer attached to the flask is needed.Making low-temperature thermometers is not easy because it may make the equipment does not work as which should be such as freezing in the sensor so the sensor can not flow the current normally, freezing on conductor so that it can not function as a good conductor, the presence of mechanical stress, and others. These make a measurement on low-temperature need a long time compared to the measurement of medium in the room temperature [1,2]. The RTD (Resistance Temperature Detector) sensor is a sensor used to measure temperature by correlating RTD element resistance with temperature [3,4,5]. RTD elements that can be used are Platinum [6,7], Nickel [8],

This paper presents a simple temperature measurement design using thermistor for industrial purposes. This paper establishes the characteristics of the resistance via temperature and it's constant since it has been difficult to determine if a thermistor has a positive or negative temperature coefficient. The practical approach was adopted to determine its characteristics where it was revealed that all thermistors are nonlinear in nature. In this design, the empirical and the practical design were compared; its implementation considers the temperature within the ranges of 35 0 C to 60 0 C which is 308K to 333K respectively. Other considerations were given to the output voltages between 0.155V -1.055V, ambient temperature of 0 0 C -25 0 C, Percentage non-linearity as low as 0.16, and a sensitivity of 0.0367V/ºC but the resolution of this device is 1ºC.The result obtained were analysed to ascertain the functionality of the experimented design via its performance and suggestions on further improvement were made.

Rotameter is one of the most commonly used local indicating type flow measuring instrument. For remote indication and control a secondary transducer like Hall Probe sensor, LVDT etc. is incorporated with the conventional rotameter. In this paper, a modified rotameter with Hall Probe sensor is used as a measuring instrument. The output hall voltage is proportional to the flow rate of the fluid and the change in fluid density may also vary the hall voltage. So this kind of variation shows incorrect flow rate if the density of the float is not taken to a very high value compared to the density of the fluid. But the density float may affect the flow rate measurement and introduce error. In this respect firstly the variation of Hall voltage with respect to liquid density is analyzed and then the measuring system is calibrated using ANN. The ANN calculates the correction factor with respect to the change in liquid density, which results in obtaining the output close to the desired output. The simulation results show that the calibration technique is efficient.
