Thermopile laser sensor - Wikipedia

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 Infrared Sensor | セラミック [Nippon …

The Thermopile Sensor generates an electromotive force by the radiant energy received from the object to be measured. Its electromotive force is a few millivolts, so it is difficult to read as it is. The minute output is amplified by an amplifier circuit to make it easy to read. At this time, the full scale of the output is determined by the supply voltage to the amplifier circuit. For example ...

CS320: Digital Thermopile Pyranometer

For thermopile pyranometers, a thermopile is used within the instrument as the sensor, and the thermal gradients are measured across hot and cold areas (black and white). The radiation intensity is proportional to the temperature differences between the two sensing areas. Accuracy depends upon the sensitivity of the material used in the sensors, the response time, and the distortion ...

CS320: Digital Thermopile Pyranometer

The thermopile pyranometer’s black surface uniformly absorbs solar radiation across the solar spectrum. The W heater keeps water (liquid and frozen) off the sensor to minimize errors caused by dew, frost, rain, and snow blocking the radiation path. Dew and rain runoff is faciliated by the dome-shaped sensor head (diffuser and body).
