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


Mount Olive, NJ -  American Sensor Technologies introduced 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 85C (-40 to 185F), 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 BSP male process connection and NPT. An optional 6-pin Bendix connection is available for direct integration into existing systems.
