The different protective elements (filter covers) like the IFM E30139 can be used for pressure sensors with screwed pressure compensation elements to avoid soiling of the ventilation diaphragm in harsh environments.

The IFM E30139 set of accessories consists of a filter cover with an integrated ventilation diaphragm and a tube fitting with a vent tube.

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 the IFM E30139.

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

To install the IFM E30139 filter cover, please follow these steps:

1. Remove the existing filter cover. See the relevant instructions for removal.

2. Screw the new filter cover (3) with its integrated ventilation diaphragm onto the base (B) and tighten it using a spanner, across flats 11. The tightening torque is 2.5…3.5 Nm.

3. Attach the tube (L = 0.5 m, internal diameter 3 mm, polyamide) onto the filter cover (3) and place the free end in a protected area.

When using a closed filter cover, please ensure the application is suitable for use without active pressure compensation. Note the following:

• 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.

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.
