Tag: infrared temperature sensor

The temperature sensor converts the relationship between various physical properties of materials and temperature into effective output signals. As the core component of the thermometer, there are many types. According to its measurement method, it can be divided into two categories: contact type and non-contact type. According to the characteristics of its material and device, it can be divided into thermal resistance type and thermocouple type. The current temperature sensor is very small, so it has great applications in many aspects of actual production, which brings a lot of convenience and practicality to our life.

The physical nature of infrared radiation is thermal radiation. The higher the temperature of the object, the more infrared radiation it emits, and the stronger the energy of the infrared radiation. The study found that the various thermal effects of the solar spectrum gradually increase from violet light to red light, and the largest thermal effect occurs within the frequency range of infrared radiation, so people turn infrared radiation into thermal radiation or heat. The infrared temperature sensor uses the radiant heat effect to cause the detection device to receive radiant energy and cause the temperature to rise, thereby changing the performance of a column in the sensor and the temperature.

Infrared temperature sensor is an IR temperature sensor, its sensitive element and the measured object are not in contact with each other, also known as non-contact temperature measuring sensor. It can be used to measure the surface temperature of human body moving objects, small targets and objects with small heat capacity or rapid temperature changes, and can also be used to measure the temperature distribution of temperature fields.

An infrared temperature sensor is a sensor that uses the physical properties of infrared rays to measure, and only measures the surface temperature. Infrared light is also called infrared light, which includes reflection, refraction, scattering, interference, absorption and other properties. This property of infrared temperature sensor makes it have a wide range of applications.
