Road Surface Temperature Sensor

Road Surface Temperature Sensor Product Introduction

Road Surface Temperature Sensor is used on asphalt and concrete roads and uses optical technology to measure the road surface temperature.Road Surface Temperature Sensor is an integrated infrared thermometer. The optical system and electronic circuitry are integrated within a metal housing. The protective cover is easy to install, and the 90° adjustable bracket allows for installation and uninterrupted measurement under various field conditions.

Internally, the Road Surface Temperature Sensor consists of a thermopile and a thermistor. All objects continuously emit infrared radiation energy into the surrounding space. By measuring the infrared energy emitted by an object, its surface temperature can be accurately determined; this is the principle of non-contact infrared thermometry. The infrared thermometer can calculate the surface temperature of an object without any contact with the target, by measuring the intensity of the infrared radiation emitted by the target—this is its greatest advantage.

Road Surface Temperature Sensor Applications

Long-distance measurement of highway pavement temperature

Bridge deck temperature monitoring

Plant canopy temperature monitoring

Grass temperature, soil surface temperature, or snow surface temperature monitoring
