The IFM E30148 filter cover is a protective element that can be used for pressure sensors with screwed pressure compensation elements. Its purpose is to avoid soiling of the ventilation diaphragm in harsh environments.

Follow these steps to remove the existing filter cover:

► Ensure that the sensor is not subjected to moisture during installation.

► Remove the filter cover (A) using an appropriate tool.

► Pull the ventilation diaphragm (C) off the base (B).

▷ The sensor is now prepared for the installation of the IFM E30148.

To install the IFM E30148 filter cover, follow these steps:

► Remove the existing filter cover as per the instructions.

► Screw the closed filter cover (2) onto the base (B) and tighten using a spanner, across flats 11.

▷ The tightening torque should be 2.5…3.5 Nm.

When using the closed IFM E30148 filter cover, please note the following:

• Please ensure that the application is suitable for use without the pressure compensation being active.

• The closed filter cover does not allow any pressure compensation of the relative pressure meter.

• The internal pressure of the sensor changes by 35 mbar for every 10 K of temperature change.

The closed filter cover is recommended only under the following conditions:

• Harsh environments.

• Applications where decreased accuracy is accepted.

Select the installation situation so that the filter cover is horizontal and the condensate can drain off due to gravity.

► Ideal orientation (1): The filter cover is in a horizontal position.

▷ The ventilation diaphragm (2) in the filter cover is in a vertical position.

► Maximum inclination of the filter cover: 30° (3).

► After use, dispose of the unit in an environmentally friendly way in accordance with the applicable national regulations.

► In case of return shipment, ensure that the unit is free from soiling, especially from dangerous and toxic substances.
