Introduction
The working principle of the laser temperature sensor is to calculate the surface temperature of the object according to the infrared radiation intensity of the object. Therefore, it can easily measure the temperature of targets that are difficult to access or move. The laser temperature sensor uses a 2-level laser for coaxial aiming, which can easily indicate the central position of the measurement point, and mark the best measurement distance. The device is suitable for small targets requiring accurate fixed-point temperature measurement. The laser temperature sensor provides a two-wire 4-20mA current output. It is easily used in a wide range of applications, especially in industrial environments with long distances and strong interference. The sensor provides different wiring modes for the laser circuit and the measurement circuit. We provide laser temperature sensors with a variety of temperature ranges, different measurement wavelengths and optical coefficients, to meet the user's different measurement requirements. The thermometer emissivity can be adjusted on site, which is convenient for users to make correction for different measured targets, and improve the effectiveness and authenticity of measurement results.

Here is Changzhou Baoyi Mechanical and Electronic Instrument Company, we make your industrial furances safer.
More than 20 years ago, Baoyi was established in Changzhou by Mr.Liu. Time has witnessed Baoyi's every step in exploring high temperature monitoring and detecting technology.
What's more, Baoyi constantly exchanges and cooperates with domestic and foreign counterparts and scientific research institutions. As a result, we successfully develops a full range of temperature measurement products. Here are some exclusive repesentatives: industrial CCTV system with temperature measurement, imaging pyrometer, SLR high temperature endoscope, infrared thermal imager, etc.
Since we have strong innovational strength, excellent quality and international service, Baoyi has fulfilled thousands of high temperature monitoring projects. Various products have been widely used in cement, glass, metallurgy, petrochemical, electric power and other industries. Our business is conducted not only all over the country but also more than 50 overseas countries and regions.
"Make furnaces safer" is not just a slogan, it has become our guideline. From the past to the future, Changzhou Baoyi will strive to build a high-tech and service-oriented international furnace monitoring enterprise.
