“…To this end, this study suggests a novel ice detection sensor by using a proprietary multi-channel thermocouple array (MCTCA) technology [42][43][44][45][46][47][48][49][50] by measuring the latent heat of fusion, which is the unique physical characteristic when liquid water turns into ice. Thermoelements can be arranged in an array or grid configuration with each node spot-welded or soldered to produce a thermocouple (TC) junction.…”

A test was performed to determine the efficacy of a novel multi-channel thermocouple temperature sensor employing “N+1” array architecture for the in-situ detection of icing in cold climates. T-type thermoelements were used to fabricate a sensor with six independent temperature sensing points, capable of two-dimensional temperature mapping. The sensor was intended to detect the high latent heat of fusion of water (334 J/g) which is released to the environment during ice formation. The sensor was embedded on a plywood board and an aluminium plate, respectively by an epoxy resin. Three different ice accretion cases were considered. Ice accretion for all cases was achieved on the surface of the resin layer. In order to analyse the temperature variation for all three cases, the first 20 s response for each case was averaged between three cases. A temperature increase of (1.0 ± 0.1) °C and (0.9 ± 0.1) °C was detected by the sensors 20 s after the onset of icing, attributed to the latent heat of fusion of water. The results indicate that the sensor design is well-suited to cold temperature applications and that detection of the latent heat of fusion could provide a rapid and robust means of icing detection.

Abstract-The purpose of this study is to achieve real-time acquisition and monitoring of temperature in large-scale industrial or agricultural production scene, and timely detect abnormal temperature. FPGA chip, multi temperature sensor and alarm control module three parts consist of FPGA alarm system obtained based on multi temperature sensor. Multi temperature sensor is used for the acquisition of relevant temperature signal in the production site, and the transmission of the collected data through the way of digital signal chip to the FPGA chip for further processing. The FPGA chip is responsible for the parameter setting, the temperature signal acquisition and the threshold comparison and so on, and according to the data processing result, it can send out the normal response control signal to the alarm module. The alarm module contains the pre-warning lights and the alarm device that it can receive the control signal and realize alarm response. The results showed that the test in planting flowers in greenhouse showed that the system is sensitive in response and small in error of temperature acquisition, in accordance with the requirements for use. As a result, the system can be widely used in the temperature monitoring in the production scene, suitable for being promoted in a variety of occasions needing for monitoring the temperature.

“…The evolution of modern science and technology has created new demands for accurate high-temperature measurement in air conditions, for instance, in solid oxide fuel cell (SOFC), nuclear reactors, heavy-duty gas turbines, and aircraft engines. [1][2][3][4] Some thermal sensors, such as optic pyrometers 5 and acoustic pyrometers, 6 have been developed for measuring high temperatures, however, their active sensing module and complicated structure make them unsuitable to meet the requirements for accurate in situ temperature measurement and device integration.…”

Facile high‐performance film thermocouple made of strontium lanthanum chromate for temperature sensing in air

Film thermocouples as the most effective tool are used to monitor the real‐time and accurate in situ temperature in harsh environment, which will demand their electrodes with high thermal‐resistant properties, high sensitivity, and stability. In this work, a series of solid solutions based on strontium lanthanum chromate were systematically investigated as new electrodes. LaCrO3 and La0.8Sr0.2CrO3 with some glass additives were chosen to fabricate high‐performance thick‐film thermocouple due to a bigger Fermi level difference between them. The thermocouple shows a high sensitivity (107.8 μV/°C) during static calibration, and an excellent reproducibility and stability during multicycle calibrations carried out up to 1550°C, resulting in a record ultra‐high temperature sensing in film thermocouples. This facile thermocouple may open up a new way to measure high temperature in air or oxidation atmosphere accurately.
