American Sensor Technologies, Inc. (AST) is a US manufacturer of pressure sensors, transducers and transmitters and related instrumentation to monitor pressure, differential pressure, and liquid level. As a market leader in various industries, AST focuses on quality product at an affordable price and excellent product support and customer service. Our product performance is verified through various third-party independent laboratories and customer qualification, our quality management system is certified to ISO 9001:2008, and our sensors and assemblies are 100% tested throughout the manufacturing process. AST pressure transducers are approved and recognized by agencies such as UL, CSA, ABSA, TUV, and ABS.
Using Krystal Bond™ Technology, AST is the leader in pressure sensing solutions, from millivolt assemblies to amplified voltage or 4-20mA output pressure transmitters. Without the use of welds, fluid filled cavities or O-rings, many of AST pressure sensors are machined from a single piece of stainless steel. These pressure sensors are built with a thick diaphragm and state-of-the-art strain gages to provide excellent accuracy, high proof pressure, long-term stability, and high electrical isolation.
Our standard 316L stainless steel pressure sensor material is popular in applications including, but not limited to: hydrogen, oil and gas equipment, and water pressure or level. Other materials for more corrosive liquids and gases include PVDF / PTFE, Alloy C276, Alloy 718, and Titanium.
AST manufactures pressure sensors using MEMS technology. LVDT sensors are manufactured as stand-alone products as well as used in pressure sensor assemblies.
