How to Measure Accurately Using a Thermopile Detector

When choosing a thermopile detector, it is a safe practice to select a detector with a higher damage threshold specification than that of the actual laser beam power/energy density (J/cm 2 or W/cm 2). 1 A good rule of thumb is to select a detector with a damage threshold that is at least twice the expected power density of the laser you are measuring. For maximum power measurement accuracy ...

Thermopile Infrared Sensor | セラミック [Nippon …

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 ...

Based on this relationship, thermopile sensor can measure the energy radiated by the object and accurately measure the surface temperature of the object. The output of thermopile sensor only increases 50-100uv for every 1°C change of the measured object, and the output voltage change corresponding to the resolution of °C is only 5-10uv, so it's better to choose the high-sensitivity ...

Thermopile and Infrared Temperature Sensors | TE Connectivity

Thermopile sensors are designed to measure temperature from a distance by detecting an object's infrared (IR) energy. The higher the temperature, the more IR energy is emitted. The thermopile sensing element, composed of small thermocouples on a silicon chip, absorb the energy and produce an output signal. A reference sensor is designed into the package as a reference for compensation ...

Thermopile - Wikipedia

· However, thermopiles can measure infrared radiation generated by the target remotely. Thus, thermopiles can conduct non-contact measurement of the temperature of all objects with a temperature above 0K, which generate infrared radiation. Thus, there is no need for external illumination while using thermopiles.
