The LTB, can be integrated into the ATB bench, measures the leakage of a silencer.
It’s a 19” rack model with a connection for compressed air, including a pressure regulator to set the desired overpressure.
Pressing the START button the system waits for target overpressure, and when this target is reached it starts measuring the air flow which goes through the silencer at a constant overpressure condition ( in case of a perfect tightness the air flow is obviously 0).
The range of air flow and target overpressure impact on the choice of sensors and they are defined according to the requests/ specifics of the client.
The test is automatically controlled by the software, which records and plots the overpressure and flow curves.
