New UHV / Cryogenic Pressure and Position Sensor Capabilities Catalog from Macro Sensors and AST

Macro Sensors introduces a new joint catalog with sister company American Sensor Technologies (AST) on the companies’ UHV / Cryogenic Pressure and Position Sensor Capabilities. The companies manufacture LVDT linear position and MEMs-based pressure sensors that withstand cryogenic gas temperatures as well as high temperature processing environments with high accuracy and stability.

The sensors can be used ultra high vacuum and cryogenic environments found in semiconductor manufacturing, photovoltaic, cryogenic systems and test equipment.

In addition to outlining Macro Sensors standard LVDT Position Sensors in measurement ranges from 0.020” to 20” that are available in stock and ready to ship, the brochure describes the company’s capability to custom design LVDTs to withstand temperatures from cryogenics to 800°F (426°C) and environments exhibiting radiation. Custom sizes, measurement ranges, output signals and materials are all available to meet application requirements.

AST manufactures gauge, absolute and differential pressure transducers in custom packages including miniature, embedded designs. Custom OEM designs are possible from 316L VAR or special alloys for high purity liquids and gases.

Both AST pressure sensors and Macro Sensors position sensors are qualified for use in the world’s harshest environments. Products have been independently tested for use in radiation, magnetic fields, and automotive conditions with continued long-term operation.
