Abstract
The utility model provides a 900 DEG C dynamic strain gauge, mainly consisting of a sensitive grid 1. The sensitive grid 1 is coated with a covering layer 2 and a bonding layer 3 is arranged at the bottom of the sensitive grid 1; a lead wire 4 is connected with the sensitive grid 1. The utility model is characterized in that the element of the bonding agent resisting to 900 DEG C high temperature of the bonding layer 3 is A1(H2PO4)3, Cr2O3, A12O3, SiO2, CrO3 and H2O. The 900 DEG C dynamic strain gauge provided by the utility model has the advantages of ability of resisting high temperatures as high as 900 DEG C, convenient use, no poison and corruption and no burning and can be used in mechanical industry, electron industry, national defense industry and chemical industry.
Description
Technical field
The utility model relates to the high temperature strain measurement technology.
Background technology
Though strainometer is little, concentrating mechanics, metallurgy, chemical industry, machinery, five specialties of electronics, be typical interdisciplinary complex art.
Domestic present strain electrical measurement probe temperature is mostly below 250 ℃, be higher than high temperature strain measurement more than 300 ℃ all from the foreign procurement strainometer, as the Tokyo survey device bonding pad of buying 600 ℃ is wanted 10000 yuan/sheet, higher strainometer will be bought from the Vishay company of the U.S., but they do not provide the service of high temperature operation technique this respect.In high temperature field strainometer technology more than 800 ℃ has been a kind of technical monopoly in the world, engine such as American and Britain, Russia big country also all spends very big cost to do the research of high temperature strain gauge for many years, but this technology is installed a slice strainometer and is wanted 10,000 yuan/sheet our strict blockade on new techniques.
Summary of the invention
The purpose of this utility model is to provide a kind of strainometer of using in high temperature field more than 800 ℃.
The utility model provides a kind of 900 ℃ of dynamic strain meters, mainly form, overlayer 2 is arranged on the sensitive grid 1, be connected to lead-in wire 4 on the sensitive grid 1 by sensitive grid 1, it is characterized in that: described sensitive grid has high temperature resistant 900 ℃ tack coat 31 time, and the composition of its cementing agent is the Al (H of 20% concentration
