SIN-P300 diffused silicon pressure transmitter Introduction: The diffusion silicon pressure transmitter adopts imported high-precision and high stability pressure sensitive chips. The sensitive chip adopts advanced micro mechanical etching technology, which diffuses four high-precision resistors on the silicon wafer to form a Wheatstone bridge. Due to the piezoresistive effect, the resistance values of the four bridge arm resistors change, causing the bridge to become unbalanced, and the sensitive component outputs an electrical signal corresponding to the pressure change. The output electrical signal is compensated by an amplification and non-linear correction circuit to generate voltage and current signals that are linearly proportional to the input pressure. CN8 Features: 1. Small size, high performance 2. Imported high-precision core, high stability, low drift 3. Internal glue sealing treatment can adapt to strong vibrations during mechanical processing, making it more durable and reliable 4. Multiple installation forms: metric, imperial, and American threads, clamps, flange connections, customizable 5.
