Crystal Silicon Diaphragm for Fast Response Time
产品描述
The PX800 has been discontinued. Please see thePX5000 as a possible
substitute. Or contact our Pressure Engineering Department.
The PX800 is an extremely high accuracy rugged solid state transducer. Excellent for use in adverse environments, the PX800’s fully encapsulated sensing element consists of a four arm strain gage bridge diffused into the surface of a single crystal silicon diaphragm. The silicon diaphragm has excellent mechanical and electrical properties; combined linearity and hysteresis accuracy less than 0.1% BFSL, fast response and maximum acceleration sensitivity.
