BNPC10 Pressure Core

BNPC10 silicon piezoresistive pressure core is the core part of pressure sensor and pressure transmitter, as a high performance pressure sensitive element, it can be easily amplified and assembled into standard signal output transmitter.

PC10 core body is diffused silicon pressure sensitive chip packages to the 316 l stainless steel shell, plus pressure by sealed inside stainless steel diaphragm, silicone oil, is passed on to the sensitive chip sensitive chips don't direct contact with the measured medium, pressure measurement of all solid state structure, so the product can be applied to various occasions, including harsh corrosive medium environment.

The PC10 core is pressure sealed with fluororubber "O" ring for easy installation.

The company can also according to the needs of users, to undertake special requirements of sensors, such as all welded structure, wide temperature compensation, high reliability, strong impact resistance and vibration resistance of pressure sensors, especially for national defense equipment supporting.
