Keywords:American Sensor Technologies AST4900? pressure sensor? gas liquid measuring?

The AST4900 from American Sensor Technologies is a MEMS-based pressure sensor used for measuring gases and liquids in high-purity applications. Using Krystal Bond technology, the stainless steel sensors are free of oil-fill, welds and internal O-rings, all of which eliminate the risk of system contamination in extreme conditions. The AST4900 media isolated pressure sensor also holds a CE EN61326 Certification and UL/cUL508 Approval.

The AST4900 is available in two standard fittings: 1/4-inch NPT Male and 1/4-inch VCR Male. Each sensing element is machined from 316L stainless steel and electropolished to remove any contaminates.

The AST4900 can be scaled with pressure ranges of 0-25 PSI [0-2 BAR] to 0-10,000 [0-700 BAR]. Compound ranges are also available for the AST4900.

In addition to high-level voltage, current and frequency output signals, the AST4900 can be packaged with cable, DIN 43650 [Form C] and Bendix [6 pin] electrical connections. Built to operate in temperatures that range from -40 C to 85 C, the AST4900's standard performance is rated to 0.25 percent BFSL. The AST4900 carries 2x over range protection, 5x burst pressure and is built to withstand more than 100 million pressure cycles. The AST4900 has been designed specifically for semiconductor applications, including test stands, semiconductor processing equipment, gas pipeline instrumentation, data loggers, panels and manifolds. Price starts at $395 with quantity discounts available starting at 10 pieces.
