Pressure sensors from American Sensor

American Sensor Technologies Inc. (AST) has introduced models AST4500 and AST4510 in a new line of media-isolated submersible pressure sensors. These units are intended for intrinsically safe IS areas when used with an approved entity barrier. Constructed in stainless steel, the AST4500 and AST4510 sensors are approved to UL/cUL 913 (CSA) Class 1 Div 1, Groups C and D. In addition, each sensor holds a CE Approval of EN 61326.

Both the new sensors are versatile and suitable for a variety of different submersible and level measurement applications, including ground water level depth measurement, well water monitoring, earthen and concrete dams, liquid level tanks, gasoline and diesel fuel tanks, irrigation, salt water holding tanks and waste water canals.

The two devices share a number of important features. Each sensor can be submerged in liquids that are compatible with 304 SS, 316L SS and Hytrel cable. The Hytrel cable is available in various lengths to meet current industry demands. Both models offer a weighted front-end nose cone and are designed to survive in harsh environments. They contain no internal O-rings, taking the guesswork out of O-ring to media compatibility. Each sensor is equipped with 100V/m of EMI/RFI protection from electrical noise.

Both models operate at a wide temperature range -20C to 85C and offer pressure ranges up to 100psi. More specifically, the AST4500 series provides pressure ranges from 0-20psi to 0-100psi and 0.88-inch diameter. For the AST4510 series, 0-5-, 0-7.5-, 0-10- and 0-15psi are the ranges offered with a 1-inch diameter. Output options are 1-5V at 4-20mA.

Pricing for the AST4500 and AST4510 starts at $325 with quantity discounts available.
