Bridge deck temperature sensor

　　Bridge deck temperature sensorIt is an important equipment to ensure the safety and normal use of bridges. It is mainly used for precise measurement of bridge deck temperature and timely reflection of the impact of temperature changes on the bridge deck. This sensor often uses high-precision thermistor or thermocouple technology, which can sensitively sense temperature fluctuations and quickly convert temperature signals into electrical signals for reading. It is sturdy and durable, and can adapt to complex outdoor environments such as high and low temperatures, rain and snow, strong winds, etc. In practical applications, this device is widely installed on various types of bridges, providing key data for bridge maintenance and management. By monitoring temperature, problems such as damage to bridge expansion joints and concrete cracking caused by temperature changes can be prevented, ensuring the safety of bridge structures and smooth driving.

1、 Product Introduction

　　Bridge deck temperature sensorIt is an integrated infrared temperature detector. The optical system and electronic circuit are integrated together in a metal casing. The protective cover is easy to install and has a 90 ° adjustable bracket; To meet various field conditions for installation and continuous measurement.

The sensor is composed of a thermopile and a thermistor inside. All objects constantly emit infrared radiation energy into the surrounding space. By measuring the infrared energy emitted by themselves, their surface temperature can be accurately determined. This is the principle of non-contact infrared temperature measurement. The infrared thermometer can calculate the surface temperature of an object by measuring the intensity of infrared radiation emitted by the target without touching the target, which is its biggest advantage.
