1 Introduction
1.1 Product overview
Emerson has designed the GDU-01-TT Ultrasonic Test Transmitter to
electrically replace the airborne ultrasound generated from a pressurized
gas leak using a piezoelectric disc. You can use the GDU-01-TT to activate
alarm conditions with any ultrasonic gas leak detector.
When gas moves from a high-pressure area to a low-pressure area, it
generates airborne ultrasound. The ultrasonic sound level depends on three
main factors:
• Pressure drop across leak
• Size of leak (area)
• Specific gas properties (molecular weight and specific gas ratio)
The GDU-01-TT is constructed from 316 stainless steel mounting hardware
and a semi-crystalline polyphenylene sulfide (PPS) enclosure. The
transmitter is battery-operated and is intended to be activated within close
proximity of an ultrasonic detector. When activated, the transmitter helps to
confirm that the ultrasonic detector is operating correctly.
The transmitter's effective range, due to the nature of the electronically
produced ultrasound, is 8m. The range may be reduced based on the level of
background ultrasound being generated in close proximity to the ultrasonic
detector that the GDU-01-TT is activating.

2 Safety guidelines
WARNING
Use in hazardous areas
The GDU-01-TT is not hazardous area certified.
Only use the GDU-01-TT in accordance with site specific safety
guidelines for non-certified equipment.
CAUTION
Only use the GDU-01-TT with Emerson approved accessories and charging
equipment.
Important
All liability for the correct function of the GDU-01-TT is irrevocably
transferred to the owner/operator if the GDU-01-TT is altered incorrectly by
personnel not authorized by Emerson or if the GDU-01-TT is used in nonconformance to its intended use.

3 Unpack and inspect
Procedure
1. Carefully remove all components from the packaging.
2. Verify the components against the enclosed packing list.
3. Inspect all components for obvious damage, such as broken or loose
parts.
4. If any components are missing or damaged, contact your local
Emerson representative or the factory immediately.
Store the transmitter in a covered, dry, clean, and safe environment. Ensure
that the storage temperature is between -20 °C and 75 °C and that relative
humidity does not exceed 95 percent non-condensing. Periodically inspect
the stored box to ensure no tampering or deterioration has occurred.

4 Operation
The key for correct operation of the GDU-01-TT Ultrasonic Test Transmitter
is in the relationship between the ultrasonic transmitter and ultrasonic
detector.
Due to the nature of electronically emitted ultrasonic waves for optimal
performance, it is very important to have the transmitter aligned
perpendicular (±2.5 °) to the decibel sensing face. The closer the GDU-01-TT
is to the detector, the higher the detector's decibel output.
The GDU-01-TT has no adjustable controls and is set up to produce
approximately 106 dB at 1 meter in single operation mode.
CAUTION
The test transmitter is not intended to output a precise sound pressure
level (SPL).
Do not attempt to calibrate ultrasound detectors using this equipment.
