American Sensor Technologies has introduced the new AST47SM Series Pressure Sensors designed to perform in the rugged environments of the steel and aluminium 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. Operating over a wide temperature of – 40 to 85C, the AST47SM units provide high accuracy of < +0.25% BFSL, with optional < +0.25% BFSL of FS with calibration data. The units are rated for over 100 million pressure cycles and have 100Vm of EMI/RFI to protect against electrical noise.
