[China Instrument Network Instrument R&D] Recently, the automatic low-temperature wind tunnel sensor wind speed sensor automatic testing device of the Jiangsu Sensing Product Quality Supervision and Inspection Center was commissioned and put into use.

The Jiangsu Sensing Center is under the charge of the Wuxi Metrology and Testing Center and provides a comprehensive public service platform for the development of Wuxi's Internet of Things industry. It mainly conducts the inspection of nine major types of sensors such as mechanics, temperature, and electricity. Jiangsu Sensing Center has always been committed to strengthening wind speed detection capabilities. Not long ago, the center's micro-speed wind tunnel completed the installation and debugging, and successfully passed the National Institute of Metrology test, coupled with the original circular low-speed wind tunnel, the wind speed detection range can be achieved (0.093-60)m/s, which is a leading position in domestic measurement technology organizations.

At present, the center's wind speed laboratory can carry out detection and calibration work for various types of wind speed sensors such as cup-type, thermal-type, ultrasonic, and MEMS, covering two common types of wind speed sensors: analog signal output and digital signal output.

The automatic wind speed sensor automatic testing device of the annular low-speed wind tunnel developed this time provides the functions of automatic control of the wind tunnel inverter, power supply of the measured wind speed sensor, and automatic acquisition and integration of the sensor analog output signal (current, voltage, frequency). The automatic detection of wind speed sensors has effectively improved the detection efficiency.

Titanium Dioxide

Titanium dioxide is the inorganic compound with the chemical formula TiO2. When used as a Pigment And Dye, it is calledTitanium Dioxide Rutile, Pigment White 6 (PW6), or CI 77891.It is a white, water-insoluble solid, although mineral forms can appear black. Rutile Titanium Dioxide is a pigment, it has a wide range of applications, including paint, sunscreen, and food coloring. When used as a food coloring, it has E number E171. World production in 2014 exceeded 9 million tonnes. It has been estimated that titanium dioxide is used in two-thirds of all pigments, and pigments based on the oxide have been valued at $13.2 billion.

The most important application areas are paints and varnishes as well as paper and plastics, which account for about 80% of the world's titanium dioxide consumption. Other pigment applications such as printing inks, fibers, rubber, cosmetic products, and food account for another 8%. The rest is used in other applications, for instance the production of technical pure Titanium Dioxide Pigment, glass and glass ceramics, Pvc Resin,electrical ceramics, metal patinas, Sodium Hexametaphosphate,catalysts, electric conductors, and chemical intermediates.
