Budget pressure sensors for demanding applications
The AST 4000 family of stainless-steel all-media isolated pressure sensors provide high-accuracy measurement of hostile media, such as corrosive liquids and gases.
Explosion-proof pressure sensor handles hydrogen
The Model AST 4600 explosion-proof pressure sensor is ideal for use in hydrogen service and other hazardous applications.
The AST4900 media isolated pressure sensor also holds CE EN61326 certification and UL/cUL508 approval.
The AST4900 is available in two standard fittings: 0.25in NPT male and 0.25in VCR male.
Each sensing element is machined from 316L stainless steel and electropolished to remove any contaminates.
This process polishes the metal surface by removing a microscopic amount of material from the work piece.
Moreover, electropolishing is a process which uses an acidic viscous medium for the transportation of ions to allow surface undulations to form a more planar surface finish.
This one-piece design can also be manufactured with Inconel 718, a nickel alloy that holds a wide range of chemical compatibility.
The AST4900 can be scaled with pressure ranges from 0-2 to 0-700bar.
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, DIN43650 (Form C) and Bendix (6-pin) electrical connections.
Built to operate in temperatures that range from -40 to +85C, this model's standard performance is rated to 0.25% BFSL.
Moreover, the AST4900 carries 2x overrange protection, 5x burst pressure and is built to withstand more than 100 million pressure cycles.
The AST4900 has been designed specifically for semiconductor applications that call for demanding price and performance requirements.
Those applications include test stands, semiconductor processing equipment, gas pipeline instrumentation, data loggers, panels and manifolds.
AST offers oxygen cleaning service to Prax Air GS-38 standards for customers that may require it.
Competitive pricing for the AST4900 begins at US $395 with quantity discounts available starting at 10 pieces.
