Steel Mill Pressure Sensor Operates in Rugged Environs of Steel and Aluminum Industry

Mount Olive, NJ, July 19, 2006... American Sensor Technologies, a New Jersey-based manufacturer of state-of-the-art, MEMS-based pressure sensing products, introduces the new AST47SM Series Pressure Sensors designed to perform in the rugged environments of the steel and aluminum industry. The AST47SM sensors are a direct plug-in for steel mill applications including rolling mills, pumps as well as coolant systems.

Featuring a one-piece sensing element, the AST47SM Series of Pressure Sensors have no silicone oil, welds or O-rings, eliminating the chance of contamination from outside media. A stainless steel housing welded to the sensing element and cable connection withstands system wash downs. The pressure sensors also feature a stress-reduced diaphragm that withstands high-pressure spikes while a special internal restrictor maintains a high frequency response of ~ 1kHz. Units also possess high proof and burst pressure ratings.

Operating over a wide temperature of - 40 to 85ºC (-40 to 185ºF), the AST47SM units provide high accuracy of < ±0.25% BFSL, with optional < ±0.25% BFSL of FS with calibration data. Units are rated for over 100 million pressure cycles and have 100Vm of EMI/RFI to protect against electrical noise.

Available in pressure ranges up to 10,000 psi (700 bar), the ASTM47SM Series Pressure Sensors offer 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.

Units are available with various cable lengths and pressure ports including a ¼" BSP male process connection and ¼" NPT. An optional 6-pin Bendix connection is available for direct integration into existing systems.
