Miniature Pressure Sensor For Pressure Measurement in Confined Areas


American Sensor Technologies, Inc. (AST) offers a miniature stainless steel pressure sensor for pressure measurement in confined areas. With an overall length of less than two inches and a diameter of 0.7 inches, the Model AST4800 Pressure Sensor can be employed in a wide range of applications including hydraulic systems, tests stands, HVAC/R, panel builders, automotive, as well as in industrial and agricultural equipment. Through the utilization of the AST’s patented Krystal Bond Technology, the Model AST 4800 incorporate a one-piece stainless steel sensing element that is free of silicone oil, welds or O-rings. This configuration eliminates the chance of contamination from outside media. In addition to a compact design, the Model AST 4800 features a high-strength stainless steel construction that is highly compatible with a diverse range of liquids and gases. Other benefits of the Model AST 4800 include its excellent response time (<1msec) and excellent price to performance ratio. The Model AST4800 operates at a broad temperature range from -20 to 105*C [4 to 220*F]. Units operate over ranges between 0-500 PSI and 0-10,000 PSI. Sensors are equipped with a 10mV/V output, providing more output signal than the competition. In addition, cable length options of 2, 4, 6 and 10 feet are offered. Competitive pricing for the AST4800 starts at $110 with quantity discounts available.
