    How to Choose an Infrared Temperature Sensor?

    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 Working Principle

    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.

    Temperature Sensor Buying Guide

    Temperature sensor is a sensor that senses temperature and converts it into a usable output signal. It is the core part of the temperature measuring instrument. According to the measurement method, there are two types of temperature sensor: contact sensor and non-contact sensor. And according to the characteristics of sensor materials and electronic components, it falls into two categories: thermal resistance and thermocouple. ATO offers you different kinds of thermocouples and RTD sensors. When you need to buy a temperature sensor, we'll cover every detail to help you make the most economical and practical decision.
