Process sensors

17 October 2017

After 20 plus years of successful ifm pressure sensor history, the new generation of PN sensors has been developed in response to requests from users.

For ease of use the PN series offers everything at a glance for enhanced transparency during setup and identification of machine conditions. Although the housing size is unchanged, the display size has been increased and the two switching status LEDs on the sensor head are bigger, brighter and can be clearly seen from all angles.

The user can change the display to switch from red or green to an alternating indication of red or green, so switching states can be highlighted or an independent colour ‘window’ can be created. The sensor is now easier and quicker to set using the three pushbuttons.

High overload protection, IP67 for all types of the series and the captive laser labelling make the new PN sensors from ifm the perfect solution even in the harshest environments.

Flexibility in use is also an important factor highlighted by our customers. So now, after fitting, the sensor can be rotated for visibility from the desired direction. This also allows multiple units to be aligned in the same direction. Another innovation in the update to the PN range is the inclusion of versions with external thread as well as internal.

The PN series covers ten different pressure ranges, starting at 1 bar negative pressure right up to 600 bar, and different units can offer switched outputs or combined switched and analogue.

One of the most important features of any modern sensor is the facility to remotely set the device, store parameters externally and ensure that the device is correct for the application. All this, and much more, is possible with IO-Link, the IEC61131-9 standardised communications protocol that ifm electronic pioneered and all sensor manufacturers are now implementing.
