“…The sensor's measurement accuracy levels are reportedly at ±0.5 ºC (or better given the observed ambient air temperature profiles of the HartRAO site (Tsela et al, 2015)). Notwithstanding their utilization for thermal monitoring of one of the world's best LLR systems (Murphy et al, 2008), RTDs have been widely reported to possess excellent accuracies over wide temperature range, improved linearization, long-term stability and an annual drift below 0.1ºC (Greenhalgh et al, 1994;Ibrahim, 2002, Sen et al, 2011.…”

“…[11]. Considering this application, some devices are already being used like RTD (Resistance temperature detector) [12], thermocouple [13], thermistor [14] and semiconductor based temperature sensor [15] etc. Surface/ skin sensing is a convenient way to non-invasively measure the temperature at process pipelines, furnaces, tanks and chemical plants.…”

This paper proposes an integrated layered doped and undoped amorphous silicon thin-film based temperature sensing device. Temperature sensing performance has been measured for thin film p-i-n (p-type-intrinsicn-type) configuration-based diode. Linear dependency of voltage on the temperature for forward-biased diode at a constant bias current is demonstrated in the temperature range of 30 -200 • C. Further, the same device has been introduced with double-walled carbon nanotubes (DWCNTs) to improve the linearity of the sensor. Comparative performance of two configurations p-i-n and p-i-n/DWCNTs for temperature sensing application has been studied. Moreover, this paper discussed the effect of the DWCNTs on the sensor parameters such as sensitivity, S and coefficient of determination, R 2 . The maximum sensitivity of the sensor, 22.34 mV/ • C for p-i-n configured device and 21.06 mV/ • C for p-i-n/DWCNTs configuration in a biasing current range of 10-60 mA have been found. We achieved a maximum value of the coefficient of determination equal to 0.99889 for a p-i-n configuration and 0.99922 for a p-i-n/DWCNTs configured device.

“…The thermistor [7] is very sensitive to temperature and has a short response time, but its stability is poor. The RTD [6,8] represented by platinum resistance is most commonly used in water temperature measurement, and it can be strictly calibrated before leaving the factory. Nevertheless, the contact measurement principle will accelerate the metal corrosion, which will influence the experiment results.…”

Water temperature and salinity are key parameters in many fields such as industry, forestry and agriculture. In this paper, we, theoretically and experimentally, demonstrate a method which is capable of water temperature and salinity measurement based on a laser frequency comb at 518 nm. We have developed a simple Michelson interferometer system. By scanning a mirror on a precision displacement platform, a pair of cross-correlation patterns can be obtained. The real-time optical distance information from these cross-correlation patterns can be used to calculate the optical distance difference changes. Temperature and salinity can be measured via these changes, aided by the empirical formulas. Compared with the reference values, our results show the differences of below 0.12 °C for temperature measurements, and 0.06 ‰ for salinity measurements. The obtained results indicate that our method can offer a powerful scheme for future temperature and salinity measurement.
