|Since the 20th century, the early 70s, we began to track
and research zirconia oxygen sensors , and cooperated
with major universities of China "985", "211"
project, successfully developed a series of zirconia oxygen
sensors ZO products, and widely used for thermal power
plants, refineries and industrial boiler flue gas oxygen
monitor, over the years has been possessed more than 60%
market share for China flue and micro-oxygen sensor oxygen,
and achieved good economic and social benefits.
September 1986 to November 1987, successfully completed
the R & D projects which be issued Hunan Science
and Technology Committee (now Hunan Science and Technology
Office) named "zirconia oxygen sensor in automobile
applications" (automotive sensor), the oxygen sensors
outstanding application in heavy machinery plant in
Beijing, Changsha Automobile Engine Factory, Beijing
Gaojing plant, Fulaerji Power Plant, Cangzhou refinery,
etc, and in December 1987 were identified, the achievement
fill the vacancy in China, reach the international advanced
level, and stockpiled as the automobile oxygen sensor
technology and product.
In 2000, our company was ISO9001: 2000 certification;
in 2005, bought molding, sintering, coating, assembly,
testing and other key equipment, mainly R & D automotive
oxygen sensor sensitive parts - zirconia ceramic head
mass production and quality control.
In 2008, the successful completion of the cars oxygen
sensor production line with annual output of 200,000,
the production of automotive oxygen sensor is passed
through more than 100,000 km vehicle real vehicle testing
and continuous aging of 1000 hours durability test.
First products off the assembly line in November 2008
provided to the Beijing public transport system, still
in use till now, were traveling more than 150,000 km
mileage, performance stability, and has still not been
In 2009, mass production of automotive oxygen sensor
is passed through two domestic carmakers bench testing
and strict performance evaluation with real cars, the
performance index reaches the industry standard, now
provide volume oxygen sensor products to two OEM factories.
In addition, our automotive oxygen sensor has been in
Beijing, Tianjin, Shenzhen, Wuhan, Xiamen and other
cities of the spare parts market and exported to Asia,
South America and other countries.
2010, we passed the TS16949, ISO14001 quality management
system certification, according to industry and international
standards, the establishment and operation management
of the production line, to ensure the quality of products.
Established in Changsha second production assembly lines
and new product R & D center: one assembly line
production plant area of 2000m2, 10 pieces (sets) major
equipment for the production assembly and testing; new
product R & D center has more than ten preparation
and testing rooms, total area of nearly 500 m2, equipped
with a laser particle size analyzer, BET surface area
apparatus, procedures precise temperature control high
temperature furnace, pressure forming machine, ball
mill, vacuum and drying oven, high-speed centrifuge,
precision electronic balance, tape devices, ultrasonic
dispersing machine,gravity dispersere,lectrochemical
workstation, sensor performance testing system, super
constant temperature systems, scanning electron microscopy,
X-ray diffraction and other advanced equipment to meet
new sensor product development, trial production needs.
Changsha production line and R & D centers further
expand the company's production scale of automobile
oxygen sensor, then ensure wide area oxygen sensor,
nitrogen and oxygen sensors and high purity concentration
oxygen pumps new products follow-up, make company's
products and technologies continued competitiveness.
