OMEGA's PX42 is a high-accuracy, millivolt output, industrial pressure transducer with a specially designed flush diaphragm for use with industrial fluids and slurries that are difficult to measure because of sticking or plugging of orifices. Its hermetically sealed, all stainless steel construction makes it suitable for the harshest industrial environments. Three meters (10') of vented 4-conductor shielded cable is standard with a ½ NPT fitting on the body for conduit installation. Pressure ranges from 0 to 3 up to 30 psi are available to cover most processing and industrial applications.

The PX42 is also available in metric configurations, with G1 ports, and models from 0-400 mbar to 0-1.6 bar pressure ranges. Please see the PXM42 for complete details, or contact our Pressure department for more information..
