American Sensor Technologies Inc. (AST) has introduced a new line of media isolated submersible pressure sensors—the models AST4500 and AST4510. These units are intended for use in intrinsically safe IS areas when used with an approved entity barrier. Constructed of all 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 AST4500 and AST4510 are extremely versatile and suitable in 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 AST4500 and AST4510 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. The AST4500 and AST4510 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 -20°C to 85°C and offer pressure ranges up to 100 PSI. More specifically, the AST4500 series provides pressure ranges from 0-20 to 0-100 PSIG and 0.88 inch diameter. For the AST4510 series, 0-5, 0-7.5, 0-10 and 0-15 PSIG are the ranges offered with a one inch diameter. Output options include: 1-5V and 4-20mA.

Pricing for the AST4500/AST4510 starts at Rs.14,794 ($325) with quantity discounts available.
