In mechanical hot-working domain, the test of temperature and control technology are crucial to assuring the quality of the product. As technical progress, domestic temperature measures those who control device to made a level have apparent progress, a few manufacturer formed his product characteristic and advantage. Nowadays, the quality that improves increasingly asks lukewarm to be being measured accordingly technology and equipment raised taller requirement, domestic manufacturer ready-made? Interviewed temperature appearance major for a big website association the Song Dynasty makes the same score a vice-president.
A big website: Above all, ask you to basically introduce temperature to measure the newest progress that accuses a technology?
Song Ping: Temperature is an important physical quantity, in process of modern industry production, such as temperature, pressure, discharge, content must have strict measurement and control with the physical quantity such as rotate speed. The lukewarm magnanimity in each physical quantity is most, estimation occupies the 50% above of gross, so temperature is measured is a major task. As the development of microelectronics and computer technology, measuring instrument (2 appearance) had gotten developing quickly. If the number of domestic production shows appearance precision,amount to one thousandth, dependability 60 thousand hours, surge, radio frequency, static discharge and pulse group wait for EMC index to amount to 3 class above, reach level of foreign coequal product.
And under photograph comparing, the progress of sensor is slower, have a lot of problems need research and solve. At present new-style temperature sensor basically has the following kinds of kinds.
A big website: Heat treatment, cast, the operating mode environment of the industry such as v is harsher, the test precision that controls appearance to temperature and dependability demand are very high. Current, measure lukewarm instrument appearance domestic and internationally to produce manufacturer to be done in this respect how? Whether contented and real need? Still exist what problem?
Song Ping: Our country heat treatment heat is virtual thermal treatment zone determines methodological state level (GB/T9452 -- 2003) stipulated heat treatment furnace presses heat preservation precision clearly (furnace temperature uniformity) cent kind. Accuse lukewarm directive precision, record appearance precision to ask among them, and heat treatment heat is virtual of thermal treatment zone determine cycle and appearance calibrating cycle have specific provision in the standard.
Effective to heat treatment furnace thermal treatment zone measures the level of lukewarm system, the national level with active comply with can is opposite only survey lukewarm system each component undertake calibrating respectively. But use heat treatment of calibrating of discrete element law to cannot satisfy heat treatment industry with the error that surveys lukewarm system major craft requirement. Because this is like the thermocouple that the factory purchases to be used directly without calibrating, meeting decentralize the gender is very big, what measure data fluky, cannot use at directive production. To assure product quality, should use the site online whole calibration surveys lukewarm system.
