About UsAST
“The mission of American Sensor Technologies, Inc. is to be “your sensor business partner...” American Sensor Technologies, Inc. (AST) was incorporated in New Jersey on January 9, 1997, by Richard E. Tasker, Michael P. Eldredge and Karmjit S. Sidhu, for the purpose of developing MEMS (Micro-Electro Mechanical Structures) pressure sensor products with their proprietary Krystal Bond™ Technology.
The dynamics of AST’s technologies allow its pressure sensing element to be packaged in virtually an unlimited number of configurations along with offering millivolt output pressure sensors, amplified voltage pressure transducers, or current output pressure transmitters. Products can be offered from our standard catalog or modified into a semi-custom or custom package for OEM applications.
AST manufactures its pressure sensor products and related items under an ISO 9001:2008 certified quality system.
Our TechnologyWith an operating strain at less than fifteen percent (15%) of the metal’s yield point, the AST pressure sensor cell has less fatigue, higher proof/burst pressure capability, and excellent long term stability. A simple example of this is inflating and deflating a balloon several times. The stretching and distortion depends on the thickness of the balloon.
The principles of pressure measurement are the same. As a diaphragm is pressurized closer to the yield point, a transformation in the shape occurs, changing the output over time. Krystal Bond™ Technology would be similar to trying to stretch a balloon as thick as a car tire. Krystal™ Bond Technology

Sensor Types
AST’s sensor technology is ideal for
hydraulic pressure measurement. Our
diaphragm offers the thickest stainless
steel membrane, it is machined from
a single piece of stainless steel, and
there is no chance for the diaphragm
to leak or crack. Packaged with some
of the most advanced electronics,
and AST produces a standard or
custom product that will perform
beyond expectations.
Available in differential pressure
ranges from 5 inches of water column
to 5,000 PSI, AST offer some
of the world’s most competitively
priced and reliable differential
pressure transducers for hydraulic
and pneumatic applications. From
filtration to flow, AST differential
pressure transducers are customizable
to your needs.
AST offers standard and custom
products with multiple outputs from
a single device, saving you time and
money.

AST offers a high strength stainless steel diapahragm as
the core of its pressure transducers. Featuring a thick
diaphragm and one piece construction, users can
expect long-term, accurate readings and reliability
for pressures up to 60,000 PSI. An optional internal
snubber can be welded in place to protect against
pressure spikes while maintaining a compact size.
