Overview
DFP2800 pressure sensor encapsulates a diffused silicon pressure-sensitive chip in a 316L stainless steel housing. Pressure is transmitted to the chip via stainless steel diaphragm and sealed silicone oil, forming an all-solid-state isolated structure. It matches foreign mainstream products in outline, assembly dimensions and sealing, with good interchangeability. Strict aging, screening and testing ensure high reliability. Special high-stability chips for low ranges (10,20,35kPa) deliver large span output and excellent linearity. Negative pressure models feature superior stability.
Applications: hydraulic systems, industrial process control, level measurement, pressure instruments, refrigeration, aerospace, etc.
