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.

2. Description
The flexible sensor is directly linked to the internal electronics in order to operate
TMSU 1 in either of two modes. The operator can either select the desired continuous
mode or the non-continuous operation. The volume can be adjusted to 7 different levels
for better amplification of the ultrasounds.
2.1 Components
The SKF Ultrasonic Leak Detector TMSU 1 is made of two main components, the
handheld unit with the controls and sensor and a pair of noise-reduction headphones.
A rubber nozzle is also provided for reduced access areas.

4. Operation
• For listening comfort while performing a leak survey, the fingertip volume control
gives instant and precise adjustment to instrument sensitivity for more effective and
safe inspections.
• The ultrasonic sensor is mounted at the end of a flexible metal tube. This tube can
be bent and twisted in multiple directions. Its diameter is small enough to perform
inspections through tight access holes and inside cabinets. A precision focus tube
is mounted over the sensor to increase the accuracy of detection and eliminate
parasitic noise.
• A red LED shows the unit is operational. If the LED does not illuminate check that
the batteries have sufficient power, and replace if necessary.
4.1 Non-continuous operation
• Slide the small switch on the right side of the unit up to the top.
• Maintain pressure on the centre of the yellow button to keep the
unit operating.
• To increase the volume (sensitivity) of the TMSU 1 push the (+) side of
the yellow button. When the desired sensitivity is reached hold the entire
button in the down position to begin your survey. Leaks are generally
found by moving the detector back and forth and up and down in the
direction of the leak source.
• As soon as you hear the typical “hissing” sound of a leak move towards the source.
Remember that ultrasounds travel through the air in a directional pattern. The
source of the leak is therefore easy to pinpoint by following the loudest signal.
• As you near the source of the leak the volume in the headphones may increase
dramatically. Reduce the sensitivity of the detector by pushing the (-) side of the
yellow button to return the TMSU 1 to a comfortable listening level.
• To turn off the detector, release the yellow button.
4.2 Continuous operation
• Slide the small switch on the right side of the unit down to the bottom,
The LED will light up.

5. Remarks
• A short acoustic beep is audible in the headphone when changing the amplification.
• The TMSU 1 can be used in combination with either alkaline (non-rechargeable) or
rechargeable AA batteries. Use only two of the same battery types at the same time.
•
When battery charge is too low, the red operation LED will not light up. When the
remaining battery charge goes below acceptable operation levels during operation,
the user will be notified with an acoustical signal (5 consecutive low frequency beeps).
• Rechargeable batteries cannot be charged while inside the TMSU 1.
