Apr 20, 2012 Used to measure water booster pressurization in pipelines and tanks and serve as part of monitoring/control systems, AST water pressure sensors maintain operating efficiency of water pumps. Krystal Bond(TM) Technology and one-piece diaphragm prevent hazardous materials penetration, and wetted materials choice withstands all types of water. Along with internal restrictor plug, features include various process and electrical connections and sensing element that withstands 500 Vdc isolation.

Pressure/Temperature Sensors feature dual output configuration.

American Sensor Technologies, Inc.    Mt. Olive, NJ 07828
Mar 22, 2012 Providing pressure and temperature outputs from single process point, AST20PT Stainless Steel Media Isolated Pressure/Temperature Sensor and AST46PT Explosionproof Pressure/Temperature Transmitter minimize process penetration points and leaks in critical systems. Model AST46PT offers pressure ranges up to 20,000 psi, while Model AST20PT ranges up to 45,000 psi. Featuring 1-piece body construction, microprocessor-controlled devices are available in temperature ranges from -40 to 250°F.

Explosionproof Pressure Transmitters operate over wide pressure range.

American Sensor Technologies, Inc.    Mt. Olive, NJ 07828
Jun 08, 2011 Available with Waspalloy material option that promotes use in processing of heavy oil and high sulfidation, AST4600 and AST46HA Series feature vented gauge reference, diaphragm thicknesses, and silicon strain gages to accommodate pressure ranges from 0-2.5 psi to 20,000 psi. Class 1, Div 1, Groups A/B/C/D approvals define AST46HA, and sealed gauge versions are approved for Class 2, Div 1 Groups A/B/C/D. Model AST46H features failure mode indicator option.

Pressure Sensors are built for sub-sea level measurement.

American Sensor Technologies, Inc.    Mt. Olive, NJ 07828
May 16, 2011 AST 4000 Series, constructed with all-316L stainless steel wetted parts, survives sub-sea environments. Even where oxygen levels are low and water movement continuous, one-piece construction with diaphragm membrane free of welds and O-rings minimizes pitting and crevices of sensor. Wet, pluggable connector completely seals electronics. Sensors provide gauge, sealed gauge, or compound gauge pressure measurement in ranges to 10,000 psi and offer accuracy of less than +0.5% BFSL at 77°.

Differential Pressure Sensor works with liquids and gases.

American Sensor Technologies, Inc.    Mt. Olive, NJ 07828
Dec 06, 2010 Able to measure line pressures up to 2,000 psi with turndown ratio of 15:1, AST5400 wet/wet differential pressure sensor uses Krystal Bond(TM) Technology and has no silicone oil, O-rings, or welds.
