II-VI Marlow designs and manufactures semiconductor-based thermoelectric coolers and subsystems, [10] which provide cooling, heating, temperature stabilization, power generation, and energy harvesting functions. [1] Its products are used for infrared sensors, fibre-optic guidance systems, thermal reference sources, refrigerators, and chillers ...
The integrated circuit sensor may come in a variety of interfaces — analogue or digital; for digital, these could be Serial Peripheral Interface, SMBus/I 2 C or 1-Wire.. In OpenBSD, many of the I 2 C temperature sensors from the below list have been supported and are accessible through the generalised hardware sensors framework [3] since OpenBSD 3.9 (2006), [4] [5]: §6.1 which has also ...
The company ranked 17th on Modern Distribution Management's 2019 list of top electrical distributors based on 2018 revenue of $505 million. [ 1 ] Summit has 25 service centers in the United States – located in New Mexico, Arizona, Texas, Louisiana, and Oklahoma – and a service center in Dubai, United Arab Emirates .
The thermoelectric effect is the direct conversion of temperature differences to electric voltage and vice versa via a thermocouple. [1] A thermoelectric device creates a voltage when there is a different temperature on each side. Conversely, when a voltage is applied to it, heat is transferred from one side to the other, creating a temperature ...
Thermoelectric junctions are typically around 10% as efficient as the ideal Carnot cycle refrigerator, compared with 40% achieved by conventional compression cycle systems. Synthetic jet air cooling A synthetic jet is produced by a continual flow of vortices that are formed by alternating brief ejection and suction of air across an opening such ...

is the resistance of the sensor at 100 °C. Pure platinum has α = 0.003925 Ω/(Ω·°C) in the 0 to 100 °C range and is used in the construction of laboratory-grade RTDs. [ citation needed ] Conversely, two widely recognized standards for industrial RTDs IEC 60751 and ASTM E-1137 specify α = 0.00385 Ω/(Ω·°C).
Thermocouples and thermopiles use the thermoelectric effect. Golay cells follow thermal expansion. In IR spectrometers the pyroelectric detectors are the most widespread. The response time and sensitivity of photonic detectors can be much higher, but usually these have to be cooled to cut thermal noise.
