“…Platinum is one of the common RTD materials with a temperature coefficient of 0.00385 -0.003923 Ω/Ω/°C and practical temperature range of -200° to 600°C and can be extended to 1000°C. Though, Platinum is the primary choice in RTD for most industrial, commercial, laboratory and other critical temperature measurements the other RTD materials used are Copper [1,2], nickel [3,4] and nickel iron alloys. However, platinum is the metal of choice for producing thin film RTDs because of its resistance to oxidation, best accuracy and it has chemical and thermal stability among the common RTD materials.…”

Current research in the automotive industry sector focuses on the application of platinum thin film sensors for exhaust temperature measurement. The prime intention of this paper is to pioneer the design and development of Platinum/Rhodium (Pt/Rh) sensors for exhaust gas temperature measurement. The developed sensors were able to endure harsh temperature environments (up to 950º C). In addition, the Pt/Rh sensors resistivity response to temperature increase was described by a second order polynomial characteristic equation. This equation can be stored in the electronics incorporated in the engine management system. Therefore, the resistance reading of the Pt/Rh sensor in the exhaust system can be decoded as a temperature measurement.

Telah dibuat lapisan tipis Cu/Ni pada variasi waktu deposisi Ni dengan metode elektroplating. Penelitian bertujuan untuk menentukan pengaruh waktu deposisi terhadap tebal lapisan Ni, struktur mikro, dan resistivitas lapisan. Sebagai elektroda digunakan pelat nikel dan tembaga, sedangkan larutan elektrolit dibuat dari paduan NiSO4 75g, NiCl2 10g , H3BO3 7,5g, dan H2O 250 ml. Deposisi dilakukan pada tegangan 1,5 volt, jarak antar elektroda 4 cm, dan suhu 60°C. Waktu deposisi divariasi dari 1 menit sampai 5 menit. Karakterisasi sampel dilakukan dengan memotret tampang permukaan Ni dan tampang lintang Cu/Ni menggunakan foto SEM, analisis kandungan unsurnya menggunakan EDS untuk sampel hasil deposisi 1 menit dan 5 menit, karakterisasi struktur mikro dengan XRD, tebal lapisan Ni dengan perhitungan, serta resistivitas keping dilakukan dengan alat probe empat titik. Hasil penelitian menunjukkan bahwa tebal lapisan Ni sebanding dengan waktu deposisi Ni. Dari foto SEM pada permukaan lapisan Ni terlihat bahwa sampel hasil deposisi Ni selama 1 menit belum menampakkan adanya butir-butir Ni sedangkan pada sampel hasil deposisi Ni selama 5 menit telah menampakkan butir-butir Ni. Dari analisis menggunakan EDS diperoleh bahwa pada lapisan Cu/Ni mengandung elemen Ni dan Cu serta senyawa NiO dan CuO dengan kadar Ni sebanding dengan waktu deposisi Ni. Dari analisis struktur mikro menggunakan XRD diperoleh beberapa fasa yaitu Cu, Ni, dan NiO berstruktur kristal sedangkan fasa CuO berstruktur amorf. Dari nilai resistivitas keping, semakin lama waktu deposisi resistivitas keping semakin berkurang.

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],
