“…One type of low-temperature sensor that can be used is an RTD-based temperature sensor (Fraden, 2010;Chowdhury and Bulbul, 2010;Blasdel et al, 2015). The economical RTD sensor has been developed by Toifur et al ( , 2020 and Khusnani et al (2019) with copper and nickel or Cu/Ni lm. The results of the study stated that the weakness of this sensor is the response time to slow temperatures for temperatures below -150°C while for temperatures above -150°C the temperature response is fast.…”

Increased export-import activities on fresh food commodities in the international market led to the idea of developing new technologies in the form of cryogenic freezers using liquid nitrogen (LN2). Along with the development of preservation methods using liquid nitrogen media, we need a tool that is able to detect changes in low temperatures in LN2 storage flasks that have economic value. Therefore the purpose of this research is to make a low-temperature sensor with copper and nickel material that has an economical price. The Cu/Ni film sensor is made with an electroplating method assisted by an external magnetic field of 200 G which is installed parallel to the deposition current. The Cu/Ni film was developed by varying the concentration of the electrolyte solution. The electrolyte solution used in the deposition process consisted of a mixture of H3BO3, NiSO4, NiCl2, and H2O. Furthermore, the Cu/Ni film that was made was tested on the LN2 medium to measure its sensitivity value in response to changes in temperature. The results showed that the Cu/Ni film sensor could detect changes in the low temperature in LN2. The results of data analysis showed that the curve relationship between voltage and temperature in the sample with the 2nd concentration (C2) had the highest relationship to influence each other between the voltage and temperature variables, and the sample had the highest sensitivity value compared to the others.

“…Freezing with cryogenic technology is much better than conventional freezing techniques [4]. The freezing technology is used in preservation in various sectors including the livestock sector [5], the health sector and the food industry [6]. In food preservation, cryogenic methods can significantly reduce the formation of ice crystals compared to traditional cooling methods, so that the weight of the product does not increase significantly and the quality of the food is maintained.…”

“…Cu/Ni low temperature sensors in the form of thin layers have been made at various variations, namely voltage [19], time [5,[20][21], solution temperature [22][23], electrode distance [11], either using or without using a magnetic field. Referring to the results of the preliminary survey/experiment, it was found that copper wire formed into a coil shape is an effective form to create a large resistance value in the wire.…”

Given the necessity of cryogenic storage and monitoring cryogenic temperatures is equally important. This study aims to determine the resistance value and sensitivity of copper wire before and after electroplating at 30˚C electrolyte temperature as a low temperature sensor. The electrolyte solution consists of NiSO4 260 g, NiCl2 60 g, H3BO3 40 g and Aquades 1000 mL. Electroplating was carried out with an electrolyte temperature of 30˚C, electrode distance of 4 cm, voltage of 4.5 volts and plating time of 4 minutes. The plating results were analyzed to determine the resistance and sensitivity of the sensor at temperatures from 0 to -160˚C. The results showed that the resistance value of the Cu coil obtained RCu = (1.44 ± 0.00) ohm and the resistance of the Cu/Ni coil RCu / Ni = (1.50 ± 0.00) ohm. The resistance value on the Cu/Ni coil (after plating) is greater than the Cu coil (before plating). While the test results of sensor sensitivity show that Cu and Cu/Ni coils have properties as low temperature sensors. Sensor sensitivity increases after plating. The sensitivity value obtained by Cu coil is S(T) = -1E-06T + 6E-05 and Cu/Ni coil S(T) = -2E-06T + 2E-05. The projection sensitivity at a temperature of -200 ˚C obtained is 0.00046 V/˚C less than the Cu/Ni coil 0.00082 V/˚C. So nickel plating on copper coil at 30˚C electrolyte temperature has successfully improved the sensitivity value of the low-temperature sensor.
