• Protect units, accessories and cables against damage.

The IFM E30467 filter cover is a protective element that can be used for pressure sensors with screwed pressure compensation elements to avoid soiling of the ventilation diaphragm in harsh environments.

Follow these steps to remove the existing filter cover:

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

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

The sensor is now prepared for the installation of optional filter covers.

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

When using the closed 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 for harsh environments and applications where decreased accuracy is accepted.

The IFM E30467 set consists of the following components for ventilation in demanding applications:

1. Adapter with integrated ventilation diaphragm

2. Tube connection

3. Plug-in element with integrated ventilation diaphragm

4. Vent tube

5. Plug-in element with integrated ventilation diaphragm

These protective elements provide better protection of the ventilation diaphragm against unfavourable environmental conditions such as heavy soiling, excess condensate, or high air humidity.

1. Remove the existing filter cover from the pressure sensor.

2. Mount the adapter (1) and the tube connection (2) to the threaded ferrule (6).

3. Loosen the locking screw (8) and turn the tube connection so that the venting faces downwards.

4. Tighten the locking screw (8) with 2.5 … 3.5 Nm.

First, install the primary protective element. Then, choose one of the following secondary element installations:

Plug-in version:

1. Push the plug-in element (3) into the tube connection (2) until the end stop has been reached.

2. Loosen the locking screw (8) and turn the tube connection into a horizontal position so that the ventilation diaphragm in the plug-in element is in a vertical position.

3. Tighten the locking screw with 2.5 … 3.5 Nm.

Tube version:

1. Push the vent tube (4) with plug-in element (5) into the tube connection (2) until the end stop has been reached.

2. Fix the tube end with the plug-in element in a horizontal position so that the ventilation diaphragm in the plug-in element (5) is in a vertical position.

Important: The tube must not be kinked or blocked.

Note: The tube version can also be used without a plug-in element. In this case, the open tube end must face downwards. A tube of any length can be used.

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 is 30° (3).

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

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