Embodiment 1

[0058] An NTC temperature sensor suitable for concrete temperature monitoring, refer to the attachment figure 1 , Which includes a body and a wire; the body includes: a stainless steel housing 2 and an NTC thermal ceramic chip 5 encapsulated inside the inner housing; one end of the stainless steel housing 2 is closed, the other end is open, and the stainless steel housing 2 The outer surface is coated with nano-TiO 2 Coating 1; the outer surface of the NTC thermal ceramic chip 5 is provided with a silver electrode layer, and the outer surface of the silver electrode layer is covered with an encapsulation layer 4; one end of the wire 8 is arranged on the NTC thermal ceramic chip 5 The other end of the wire 8 extends from the open end port of the stainless steel housing 2 to the outside of the stainless steel housing; the inner surface of the stainless steel housing is provided with a thermally conductive silicone grease sealing layer 3, and the thermally conductive silicone grease...

Embodiment 2

[0060] An NTC temperature sensor suitable for monitoring the temperature of concrete. It is the same as Embodiment 1, except that the material of the encapsulation is epoxy resin or fiber reinforced resin bar. The encapsulation layer is a glass seal protection layer. The encapsulation layer can not only provide the first protective layer for NTC thermal ceramic chips; it can also reduce the impact of subsequent packaging processes on the chips and leads. The wire is a three-core sensor cable; the material of the stainless steel shell is SUS304.

Embodiment 3

[0062] An NTC temperature sensor suitable for concrete temperature monitoring. Same as Example 1, except that the main performance parameters of the NTC thermal ceramic material are: R 25℃ =(10~20kΩ)±2.5%; B 25 / 85 =(3900~4200K)±2.0%); NTC thermal ceramic materials with this performance parameter can better match the temperature variation range of concrete.

Abstract

The invention relates to the field of concrete temperature monitoring, and specifically relates to an NTC temperature sensor suitable for concrete temperature monitoring, a preparation method and application. The NTC temperature sensor comprises a body and a lead, wherein the body comprises a stainless steel shell and an NTC thermosensitive ceramic chip packed in the shell, one end of the stainless steel shell is closed, the other end thereof is open, the outer surface of the stainless steel shell is provided with a Nano TiO2 coating, the outer surface of the NTC thermosensitive ceramic chip is provided with a silver electrode layer, a packaging layer wraps the outer surface of the silver electrode layer, one end of the lead is connected with a lead on the NTC thermosensitive ceramic chip,and the other end thereof extends from the opening end of the stainless steel shell to the outer side of the stainless steel shell. The sensor can measure a wide range of temperature, responds rapidly, has high accuracy, improves concrete temperature monitoring quality and efficiency and lowers engineering cost, and promotes accurate monitoring and effective control of concrete temperature.

Description

Technical field [0001] The invention relates to the field of concrete temperature monitoring, in particular to an NTC temperature sensor suitable for mass concrete temperature monitoring, and a preparation method and application. Background technique [0002] In the background art of the present invention, the disclosed information is only intended to increase the understanding of the overall background of the present invention, and is not necessarily regarded as an acknowledgement or any form of suggestion that the information constitutes the prior art known to those of ordinary skill in the art. [0003] In recent years, with the vigorous development of infrastructure construction, higher requirements have been put forward for the quality control of concrete projects, and temperature monitoring is the key to quality control of concrete projects, especially during the construction process. Ambient temperature and internal temperature and their changes are one of the important fact...
