Preamble PREAMBLE 1. DEFINITION OF THE ATEQ F CLASS The ATEQ F CLASS are compact air/air REFERENCE PART TEST PART leak detectors used to test the air- DIFFERENTIAL SENSOR tightness of parts on production lines. They are specially adapted for automatic and semi-automatic workbenches.
NDIRECT RESSURE RISE MEASUREMENT The test part is placed in a sealed bell and the ATEQ F CLASS is pneumatically connected to the bell. The part is externally pressurised (with up to 20 MPa or 200 bar), and the bell is lightly pressurised. In the event of a part leakage, the pressure in the bell will rise.
This method is also used for SENSOR deformable parts and parts with a TEST PART constant temperature which is different from ambient temperature. central zero test offers a considerable time gain (two parts tested simultaneously). UM-23100B-U User manual ATEQ F CLASS Page 7/90...
Pressurisation of the test and reference parts. At the end of the fill time, The fill time the ATEQ instrument checks the test pressure. If this is not correct, it will signal a test pressure fault. The test and reference parts are completely cut off from the air supply, but are pressurised to the test pressure level.

FCLASS The ATEQ F CLASS is supplied in a moulded, painted sheet metal case and rests on four rubber feet. The upper cover is attached to the main body by two screws. The shape of the case has been altered so that the instrument fits easily inside it. A power supply unit is supplied with the instrument.
2.2. C ONNECTOR DETAILS 2.2.1. Electrical connectors The ATEQ F CLASS operate on a voltage of 24V DC either: using the 24V DC transformer supplied with the instrument, or via the networking cable when the instrument is a slave. 2.2.1. 1) J3 Connector (I/O inputs/outputs)

Page 55
Chapter 4 – Functions of the instrument To avoid having to carry out learning cycles too often, the ATEQ instrument saves the last ten values of parts considered as very good (result close to 0) and recalculates the transient using the average value.
