The IFM PN4221 is a pressure sensor monitor with an LED display that shows the current pressure in real time at the point of measurement. Its 1/4" NPT threaded port allows direct insertion into standard pressure lines for straightforward installation. This model is intended for industrial automation and machine control, enabling quick local verification of pressure for diagnostics and process monitoring. Backed by IFM, the PN4221 combines a compact housing with a clear LED readout to provide on-site visibility of system pressure.
