Definitions
- the invention relates to a sensor, a filter element with a sensor and a use of a filter element with a sensor.
- a disadvantage of the known filter elements is that the sensors are often made relatively large in order to detect and evaluate one or more physical variables.
- the production of such filter elements is relatively expensive.
- larger sensors are difficult to mount on filter elements.
- the detection of very small pressure differences in the range 10 - 500 Pa is possible in the prior art only with relatively large sensors and requires a lot of space.
- the connection of such a relatively large sensor to a filter element is quite difficult and expensive.

As a result, pressures can be measured accurately and efficiently.
- the transducer element could be designed as a transistor or resistor on a silicon membrane. As a result, a very reliable arrangement is created.
- the electronics chip and the sensor chip could be arranged side by side on a circuit board. As a result, a very flat structure is realized.
- the electronic chip and the sensor chip could be electrically conductively connected to one another by bonding wires.
- the electronics chip and the sensor chip can be placed very close to each other. The usage of
- Bonding wires allow easy fabrication because the bonding wires are mounted on the sides of the chips facing away from the board.

- the sensor chip could comprise a silicon substrate in which a membrane is etched, which is free of electronic devices and / or oxide layers except for transducer elements.
- Transducer elements are preferably designed as n- or p-doped regions on and / or in the membrane. By etching the membrane also a compact structure of the sensor chip is generated, as an intrinsic in the

- Membrane surface facing a membrane A second membrane surface which faces the first membrane surface faces the atmosphere or another volume fluid-tightly separated from the volume.
- the functional volume in the literal sense of this document is formed only by the sums of the extensions of the electronic chips and sensor chips in each case in the x, y and z directions.
- the bonding wires, the Greierhügel and / or parts of a Abdichtkranzes contribute nothing to the functional volume or increase this not.
- the bonding wires, the Druckierhügel and Parts of the sealing ring protrude beyond the functional volume.
- a part of the Abdichtkranzes, which is arranged between an electronic chip and sensor chip, has to be disregarded in the total extension of the functional volume in the x, y or z direction. Decisive are only the dimensions of the electronic chips and sensor chips as such in the respective directions. In Fig. 5, the calculation or detection of the extensions x and z

- Filter elements are deposited.
- the filter elements settle by a particle storage and must be replaced regularly, the change time depends heavily on the use of the device, such as the type of prints and the paper used. Because of this, a change in fixed time or counting intervals does not make sense. Thus, monitoring of the condition of a filter element is required. This can be done in particular by measuring a pressure difference. Usual sensors for pressure difference measurement must be installed in the device.
- connection of the sensor to a device electronics is required. This connection usually takes place via a cable. Cabling is too uncomfortable to use a filter element in a laser printer that requires a simple, layman-friendly replacement.
