Advantages of Thermopile sensor. It is non-contact based temperature sensing device which uses infrared radiation for heat transfer. It is used for temperature measurement of moving objects where contact based sensors are not feasible. It is available in smaller sizes. It produces larger output voltage due to use of multiple thermocouple devices.
Coherent ® hochsensitive Thermopile-Sensoren sind so konzipiert, dass sie eine breite Spektralempfindlichkeit aufweisen, um eine Reihe von Lasern mit unterschiedlichen Wellenlängen zu erfassen. Die große aktive Fläche und die hohe Auflösung dieser Thermopile-Sensoren ermöglichen genaue Messungen von Lasern mit geringer Leistung.
· For heat transfer, all thermopile sensors use infrared radiation and are also used for non-contact temperature measurements. As a consequence, it is used in infrared thermometers, industrial pyrometers, lifecare instruments, moving object temperature control, etc. Thermopile connections: With a few thermocouples linked in a chain. At temperature T1, the two top thermocouples are a connected ...
Thermopile laser sensors (Fig 1) are used for measuring laser power from a few µW to several W (see section ). The incoming radiation of the laser is converted into heat energy at the surface. This heat input produces a temperature gradient across the sensor. Making use of the thermoelectric effect a voltage is generated by this temperature gradient.
Thermopile sensors. At room temperature, thermoelectric materials based on bismuth telluride are the most effective ones and therefore suitable for accurate temperature difference measurements. Coupling several thermoelements in series to form thermopiles increases the sensitivity even further. This is interesting for many applications, such as thermal radiation detectors, calorimeter ...

SENSOR SOLUTIONS /// AN THERMOPILE SENSOR Page 10//2018 1 This document is meant to provide an introduction in the functionality and usage of thermopile sensors for contactless temperature measurement. Thermopiles are mainly used for contact-less temperature measurement in many applications. Their function is to transfer the heat radiation emitted from the objects into voltage …
Thermopile Sensors measure the temperature of a substance by measuring such infrared radiant energy. Fig 3: Heat Transfer. Infrared Radiation / Absorption / Reflection. Every object emits infrared energy, at the same time it also absorbs infrared energy from other objects. Absorbing infrared rays raises the temperature of an object, and radiating it lowers it. Figure 4 shows the relationship ...
In einem Thermopile (Abb. 2) sind mehrere dieser Thermoelemente hintereinander geschaltet und erzeugen dadurch wesentlich höhere Spannungen und eine höhere Empfindlichkeit.
