Abstract

A two-dimensional planar temperature field test sensing element and a manufacturing method thereof belong to the field of sensing element manufacturing methods and test methods. The two-dimensional planar temperature field test sensing element is composed of a film in a first layer, a sensitive element array and transverse electrodes in a second layer, an insulated thin layer in a third layer, longitudinal electrodes in a fourth layer, and an insulated protective film in a fifth layer. The film in the first layer is made of a plastic film material. The second layer includes the sensitive element array and the transverse electrodes which are printed on the film in the first layer by a printing method, wherein the sensitive element array is printed with a conductive polymer composite material, and the transverse electrodes are printed with conductive silver pulp. The insulated thin layer in the third layer is printed with resin. The longitudinal electrodes in the fourth layer are also made by printing. The insulated protective film in the fifth layer is printed with resin.

Meanwhile, the test sensing element can be mass-produced under printing process conditions, is low in cost, and has a good effect.

Description

technical field [0001] The invention relates to a manufacturing method and a testing method of a sensing element, in particular to a two-dimensional plane temperature field testing sensing element and a manufacturing method thereof. Background technique [0002] At present, the methods used for two-dimensional plane temperature field testing are mainly divided into contact testing method and non-contact testing method. The contact test method mainly uses multi-point thermistors or thermocouples for testing. This method has limited layout, and each thermistor must be connected to the test line, which takes up a lot of space and affects the accuracy of the test. In terms of space constraints, environmental conditions and Under the influence of factors such as equipment requirements, it is difficult to achieve effective and feasible temperature field measurement. The indirect test method mainly includes acoustic and image processing measurement methods, among which the acousti...

Problems solved by technology

In engineering and indoor experiments, in order to obtain its two-dimensional temperature field distribution, the usual method is to embed or insert many thermistors or thermocouples into the soil, and conduct temperature field tests through direct contact, which will have an impact on the structure of the object. Disturbance, affect the temperature field test accuracy

And the temperature sensing element is limited by the high temperature resistant material, the contact temperature sensing element is generally only suitable for the temperature measurement environment in the medium and low temperature environment
