Mt. Olive, NJ - October 10, 2008....American Sensor Technologies (AST), a New Jersey-based manufacturer of state of the art MEMS-based pressure sensing products, offers a line of pressure sensors with high pressure ratings to 60,000 PSIG (4,000 Bar) that offer high accuracy pressure measurement and long life in the abusive environmental conditions of hydraulic systems. Typical applications for the AST47HP pressure sensors include: pumps and accumulators, valve controls, test stands, hydraulic lifts and booms as well as high-pressure wells, hydraulics and down hole instrumentation
A sealed housing free of silicone oil, welds or O-rings eliminates the chance of sensor contamination from outside media such as rain, ice and high-pressure wash down. Units also possess high proof and burst pressure ratings due to a stainless steel construction.
With AST's Krystal Bond Technology, the sensing element offers a thick diaphragm that eliminates long-term drift, which can be common in high pressure and high cycle applications. Units are rated for over 100 million pressure cycles and have 100V/m of EMI/RFI to protect against electrical noise.
To address different pressure requirements, the AST47HP Pressure Sensors are offered in a variety of high-pressure fittings including:
o ¼" BSP Male [10,000 - 15,000 PSI]
o ¼" NPT Female [10,000 - 15,000 PSI]
o 9/16-18 UNF Male with 37º Flare [10,000 - 20,000 PSI]
o F250C Female Autoclave [10,000 - 45,000 PSI]
o M16*1.5 Female with Sealing Cone [10,000 - 60,000 PSI]
Operating over a wide temperature range of - 40 to 85ºC (-40 to 185ºF), the AST47HP Pressure Sensors offer a standard accuracy of < +0.25% BFSL. AST47HP Pressure Sensors are available with outputs of 10mV/V (50mV), 0-5V (3 or 4 wire), 0-10V (3 or 4 wire), 1-5V, 1-6V, 1-10V or 4-20mA (loop) to address different application requirements. A wide variety of electrical connections are also available with cable, Hirshmann connectors, and military connectors.

AST manufacture state-of-the-art, MEMS-based pressure sensors, transducers and transmitters that offer the best price-performance ratio in the industry. Through the acquisition of noted LVDT manufacturer Macro Sensors (http://www.macrosensors.com/), AST also offers a full line of linear/rotary position sensors, as well as related instrumentation. Common applications of AST sensor products are in industrial OEM, hydraulic systems, fuel cells, medical gases, HVAC/R, refrigeration (ammonia, Freon, CO2), oil & gas exploration and production, and off-road vehicles. By combining exotic metals and AST's exclusive, proprietary Krystal Bond(TM) Technology (an advanced process in which inorganic materials are molecularly diffused onto a metallic surface in the presence of certain gases) in the manufacture of its pressure sensors, AST can produce high-performance pressure units that support the specialized needs of key niche markets. Many AST products are UL listed as intrinsically safe and certified for explosion-proof required environments.
