Abstract
A gas-sensitive ceramic testing apparatus, comprising a gas distribution apparatus (1), a testing cavity (6), a testing module (7), and a gas-sensitive ceramic placement mesa (8). The testing cavity (6) is a flat cube and of a small volume. The height of the testing cavity (6) is no greater than twice of the height of a portion of a gas-sensitive ceramic on the placement mesa (8) appearing in the testing cavity (6). The structure, with respect to application features of a gas-sensitive ceramic, reduces the volume of the testing cavity (6) and reduces the amount of a testing gas required without affecting testing effects. Testing gases for the gas-sensitive ceramic are mostly harmful substances; therefore, such improvement reduces costs for waste gas treatment, and also facilitates production safety and environmental protection.
Description
本发明涉及一种气敏陶瓷测试装置，属于测试装置领域。The invention relates to a gas sensing ceramic testing device and belongs to the field of testing devices.
气敏陶瓷作为一种性能优秀的气体传感器，部分型号已经获得了广泛的应用，但是目前还没有针对气敏陶瓷区别于其他气体传感器的特性而研发的测试装置，在一定程度上掣肘了气敏陶瓷的发展。As an excellent gas sensor, gas-sensitive ceramics have been widely used in some models, but there is no test device developed for the difference between gas-sensitive ceramics and other gas sensors. The development of ceramics.
发明内容：Summary of the invention:
本发明要解决的技术问题是提供一种针对气敏陶瓷区别于其他气体传感器的特性而适配的测试装置。The technical problem to be solved by the present invention is to provide a test apparatus adapted to the characteristics of a gas sensitive ceramic different from other gas sensors.
为解决上述问题，本发明是通过以下技术方案实现的：In order to solve the above problems, the present invention is achieved by the following technical solutions:
一种气敏陶瓷测试装置，包括配气装置、测试腔、测试模块和气敏陶瓷摆放台，其特征在于：所述测试腔呈扁立方体且容积小，测试腔的高度不超过摆放台上气敏陶瓷出现在测试腔中的部分的高度的两倍。A gas sensing ceramic testing device comprises a gas distribution device, a test chamber, a test module and a gas sensitive ceramic placing table, wherein the test chamber has a flat cube and a small volume, and the height of the test chamber does not exceed the placement table. The gas-sensitive ceramic appears twice as high as the portion of the test chamber.
作为优选，所述气敏陶瓷摆放台可同时放置多个气敏陶瓷。Preferably, the gas-sensitive ceramic placing table can simultaneously place a plurality of gas-sensitive ceramics.
作为优选，所述测试模块还包括一个可以与电脑相连的通讯端口。Preferably, the test module further includes a communication port connectable to the computer.
作为优选，所述配气装置中的气体为混合气体，其中测试目标气体所占比重不超过1％。Preferably, the gas in the gas distribution device is a mixed gas, wherein the specific gravity of the test target gas does not exceed 1%.
作为优选，所述测试腔还与常规气体配送机构相连通。Preferably, the test chamber is also in communication with a conventional gas distribution mechanism.
与现有技术相比，本发明的有益之处在于：因为一般气体传感器在测试时需要测试稳定性和动态响应特性，所以传统的气体传感器测试腔容积较大以保证通入的气体流速平稳，避免对传感器测试造成干扰。而由于气敏陶瓷一般用作报警，对其性能进行测试时主要考虑的因素是测试气体的
浓度，属于静态测试，所以不需要大容积的测试腔。而且，由于气敏陶瓷的感应对象往往是有害气体，较小的测试腔也能降低对测试气体的需求，有利于环境健康，减少废气处理的成本。Compared with the prior art, the invention has the advantages that since the general gas sensor needs test stability and dynamic response characteristics during testing, the conventional gas sensor test chamber has a large volume to ensure a smooth flow rate of the introduced gas. Avoid interference with sensor testing. Since gas-sensitive ceramics are generally used as alarms, the main factor to be considered when testing their performance is the test gas.
Concentration, which is a static test, does not require a large volume of test chamber. Moreover, since the sensing object of the gas-sensitive ceramic is often a harmful gas, the smaller test chamber can also reduce the demand for the test gas, contribute to environmental health, and reduce the cost of exhaust gas treatment.
