WTG-2SP Warble Pipetone Generator
This is an option that is used for test conditions where it is not possible to physically place the standard
WTG-1 Warble Tone Generator, such as in pipes or in certain heat exchangers or tanks.
1. Features:
a. Threaded Pipe Fitting: The ultrasonic transducer is at this end. When testing, make sure that the
transducer is positioned so that it can adequately "flood" the test area. This can be accomplished
by screwing the male nipple connection into a threaded hole. The nipple size is 1" NPT.
b. Warble Rate Indicator Lamp (top). This LED will flash to indicate that the unit is on.
c. Variable Intensity Control (top). This dial has whole numbers and decimal numbers. The whole
number appears in the window. Maximum output is "10" and minimum output is "0". The dial can
be rotated counter clockwise to reduce intensity of output and clockwise to increase intensity
output. There is a lock lever located to the right on the variable intensity control dial. Should a
specific output intensity be required, the level may be preset and locked into position so that it will
not be inadvertently moved during a test. To lock, press the lock lever down. to unlock, push the
lock lever up.
d. On/Off Switch (middle). To turn the unit on, push the switch to the left.
e. Recharge Jack (bottom). This receptacle is compatible with the Ultraprobe Tone Generator Battery
recharger. To use, follow the instructions for the recharge jack, section 1-H (page 2).
f. LED Indicator Lamp (bottom). This red lamp will glow only if the battery needs to be charged.
Should the light glow, charge the battery immediately.
g. Adapters: The adapter kit consists of an acoustical foam rubber shield/sleeve - inside the sleeve is a
coupler, 1" female pipe thread to female pipe thread. There are two adapters: one is 3/4" female and
the other is 1/2" female that can be screwed on to the coupler. When attached, the adapters can
then be screwed on to an appropriate male threaded connection.
