OMEGA's PX42 is a high-accuracy, current output, industrial pressure transmitter 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 2-conductor vented, shielded cable is standard with a ½ NPT fitting on the body for conduit installation. Pressure ranges from 0 to 3 psi to 0 to 30 psi are available to cover low-pressure processing and industrial applications.

The PX42 is also available in metric configurations, with M 1 male threaded port and ranges from 0-400 mbar to 0-1.6 bar. Please see the PXM42 for complete details, or contact our Pressure department for more information..
