MEMS-Based SS Pressure Sensor Measures Gas and Liquids in High Purity Applications
American Sensor Technologies offers the AST4900 pressure sensor for use in the measurement of gases and liquids in high purity applications. Utilizing Krystal Bond Technology, these 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 media isolated pressure sensor also holds a CE EN61326 Certification and UL/cUL508 Approval. It is available in two standard fittings: 1/4" NPT Male and 1/4" VCR Male. Each sensing element is machined from 316L stainless steel and electropolished to remove any contaminates. The one-piece design can also be manufactured with Inconel718, a nickel alloy that holds a wide range of chemical compatibility. The sensor 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. In addition to high-level voltage, current and frequency output signals, the sensor 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, this model’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. Pricing begins at $395 with quantity discounts available starting at 10 pieces.
