G.M. Wu Hao was invited to visit HKST

General Manager, Wu hao was invited to visit HKST in Hong Kong, branch of AST in U.S.A.

AST was founded by Richard E. Tasker, Michael P. Eldredge & Karmjit S. Sidhu in New Jersey in Jan.9, 1977, whose purpose is to develop MEMS(micro electro mechanical structure), using a unique patented Krystal Bond &Trade technology for pressure sensors.

Main company information introduction:

Hong Kong sensor technology (HKST) - Hong Kong, China

2001, AST built a branch in Hong Kong to support Asian market.  Today, HKST has developed  a company with manufacturing capability and distribution network, to fully support the continued growth in Asia sensor market.

Macro Sensors Corporation - pennsauken, New Jersey

June 2005, AST acquired Marco Sensors, one branch of Howard A Schaevitz Technologies. Then it improved the position sensor in the pressure of the product. Macro Sensors in Pennsauken, NJ manufactured LVDT and RVDT position sensors.

MEMS (micro electro mechanical systems) pressure sensor technology

"Krystal Bond "technology is the latest pressure sensor technology using a metal micro-mechanics and MEMS strain gauge system. This technology provides precise repeatable measurement." And Karmjit Sidhu, vice president of business development, AST founder, materials science PHD of New Jersey institute.  Strain gauge is formula distributed in the surface of the metal diaphragm, the use of inorganic materials and high temperature. When the temperature decreases, the inorganic adhesive material will be solid, to ensure the silicon strain gauge sensors in the center of the top, so making a single sensing element.

Why should use Krystal Bond Technology?

The sensor diaphragm shape is controlled at less than 15% of its yield strength, making the AST sensor diaphragm to reduce the strain, thereby increasing the durability of the sensor, increased ability for over pressure and limit damage, to increase the stability of long-term work. For simple example, a balloon inflated and deflated several times, you can see the balloon wall thickness to determine their resilience. The thicker Balloon wall is, the stronger resilience is. When sensing diaphragm deformation under pressure, "Krystal Bond Technology ensures that the pressure sensing diaphragm is out of influence from other pressure, the freely changed due to pressure arising. This process likes a balloon, bicycle tires, air tires, etc., when inflation pressure on the same principle.
