excellent stability and accuracy over a long service life.
Electrical connection is via a detachable DIN connector
allowing easy access to zero and span adjustment. Standard

pressure connection is 1/2” BSP, but other options are available.
Pressure ranges are available from 0- 100 mbar to 0- 900 mbar.
