- AO910W scattered silicon input level transmitter
measuring principle
The product uilizes the piezoresistive effect of difused silicon,a specific crystal orientation on monocrystaline
silicon wafers,to measure electrical bridges.By employing laser tuning and computer compensation algorithms,the
temperature characteristics have been significantly improved.The sensor has also evolved from early analog designs to
digital ones,enhancing the overall stability and reliability o the device.
The transmission cable has an internal gas conduit that transmits atmospheric pressure to the pressure chamber of
the front end sensor,thereby balancing changes in the atmosphere.
