Embodiment Construction

[0025] The present invention will be described below in conjunction with the accompanying drawings.

[0026] The invention discloses a multi-section temperature sensor, which includes more than two thermistors and sensor seats corresponding to each thermistor, and also includes a hollow spacer made of temperature isolation material, and each thermistor is arranged on the In the corresponding sensor seats, the sensor seats are arranged side by side at intervals, and the adjacent sensor seats are connected through spacers, and the output signal lines of each thermistor are merged through the hollow parts of the sensor seats and the spacers and finally connected from the sensor at one end. seat leads.

[0027] The thermistor in the multi-section temperature sensor of the present invention can adopt two according to actual needs, as figure 1The first preferred structure shown includes two thermistors: the first thermistor 101 and the second thermistor 102, and two sensor seats re...

Abstract

The present invention relates to a multi-segment temperature sensor and a preparation method thereof. The multi-segment temperature sensor comprises more than two thermistors and the sensor bases of which the number corresponds to the number of the thermistors, and also comprises hollow isolating sleeves made of temperature isolating materials. The thermistors are all arranged in the corresponding sensor bases, the sensor bases are arranged side by side and at intervals, the adjacent sensor bases are connected via the isolating sleeves, and the output signal wires of the thermistors are joined via the sensor bases and the hollow parts of the isolating sleeves and finally are led out from the sensor base at one end, thereby realizing the hierarchical measurement of the concrete, the soil layer and the rock stratum, effectively reducing the construction difficult and the cost, improving the reliability and the precision of a whole safety monitoring system.

Description

technical field [0001] The invention relates to the technical field of health monitoring of geotechnical engineering, in particular to a multi-stage temperature sensor used for temperature measurement of concrete, soil layers and rock layers and a preparation method thereof. Background technique [0002] In the safety monitoring of geotechnical engineering such as concrete, soil and rock layers, it is necessary to monitor physical quantities such as stress and strain, temperature, joint opening, leakage and deformation of geotechnical engineering to analyze and judge the safety of geotechnical engineering . Among them, the temperature is usually monitored and obtained by installing multiple temperature sensors located at different depths. There are two commonly used methods: one is to bury multiple independent temperature sensors in one installation hole at different depths, each independent The temperature sensors all lead out cables, so it is necessary to open large holes...
