1. Introduction

The SKF Ultrasonic Leak Detector TMSU 1 is designed to detect leaks in compressed air systems,
pneumatic brake systems, vacuum systems, pressurized gas storage, and steam traps.

1.1 Intended use

It can be used to verify the integrity of compressed air systems, and the tightness of
containers, trucks, buses, cars, storage systems, building envelopes, containment walls,
tanks, recreational vehicles, and more....

1.2 Principle of operation

The principle of operation of the TMSU 1
can be compared to a special microphone,
sensitive only to high frequency ultrasounds.
A sensitive piezoelectric crystal is used as a
sensor element. Minute sound waves excite
the crystal, creating an electrical pulse that
is amplifi ed and then "heterodyned" or
translated into an audible frequency that
the user can hear through a pair of noise-
reduction headphones.

1.3 Distinguishing features

• As a leak passes from a high to a low pressure, it creates turbulences.
These turbulences generate a high-frequency sound component which is detected
by the sensitive piezoelectric element, allowing the user to quickly guide the sensor
to the loudest point in order to pinpoint the leak.
• The TMSU 1 indicates the presence of a leak by producing a quality signal that is
truly representative of that leak. In fact each leak has its own unique sound.
TMSU 1 is not producing a "beep" but a real signal, an amplifi ed "image" of that
unique sound.
