Problems solved by technology

[0002] The current temperature measuring cables use thermistors, PN junctions or thermocouples as temperature measuring elements and output wires to connect them. These temperature measuring cables generally have complex overall structure of the system, many hidden fault points, and large errors in repeated temperature detection; cables The interface is not easy to seal, and the corrosion resistance is poor; the service life is short, which affects the temperature measurement effect

The thermometry cable includes temperature sensor chip at least, protecting node which is out of the sensor chip and directing line which is connected with the sensor chip, the specific characteristics are: said top end of the directing line is T type injection part, the two sides of the T type injection part are two-core waterproof sealing connector, a circuit board which is connected with the left and right two-core connectors and the directing line is mounted in the inner of the T type injection part; the sensor chip is a digital temperature sensor chip which integrates the temperature sensor and signal pickup circuit, analog-to-digital conversion circuit. The invention has high accuracy, strong interference immunity, corrosion prevention, flexibility, tension; it can be widely used in various signals sensing system of temperature monitoring and detecting system, such as warehousing, agriculture,fisheries industry, mining industry.

Description

(1) Technical field [0001] The invention relates to an electronic detection device, in particular to a temperature measuring cable. (2) Background technology [0002] The current temperature measuring cables use thermistors, PN junctions or thermocouples as temperature measuring elements and output wires to connect them. These temperature measuring cables generally have complex overall structure of the system, many hidden fault points, and large errors in repeated temperature detection; cables The interface is not easy to seal, and the corrosion resistance is poor; the service life is short, which affects the temperature measurement effect. (3) Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the invention provides a temperature measuring cable with high precision, strong anti-interference performance and good sealing performance. [0004] The present invention is achieved through the following technical solutions: [0005] A ...
