American Sensor Technologies

American Sensor Technologies, Inc. (AST), founded in 1991 and headquartered in Mt. Olive, New Jersey, specializes in pressure transducers and transmitters built on their proprietary Krystal Bond Technology — a process that molecularly diffuses inorganic materials onto metallic surfaces to create high-performance pressure sensing elements from a single piece of stainless steel, eliminating oil fills, welds, and internal O-rings. Now part of TE Connectivity, AST's product lines include the AST4500/AST4510 submersible pressure sensors rated IP-68 for groundwater level monitoring, wastewater canal measurement, and liquid tank applications (0-5 PSI to 0-100 PSI ranges); the AST4400 intrinsically safe pressure transmitter with UL/cUL 913 Class 1 Div 1 approval for hazardous environments (0-25 PSI to 0-10,000 PSI); the AST20HA precision transducer achieving ±0.1% BFSL accuracy with ranges up to 45,000 PSI and ABS marine approval; and the AST5400 differential pressure transducer with a 15:1 turndown ratio for filtration monitoring and flow measurement. All Krystal Bond sensors deliver over 100 million pressure cycle life with IP-66 protection standard. AST holds ISO 9001:2015 certification with UL and CSA approvals across oil and gas, water management, chemical processing, and HVAC industries.
