DTTH High Temperature Transducers
Mounting of high temperature transducers is similar to standard
DTTN transducers. High temperature installations require acoustic
couplant that is rated not to “flow” at the temperature that will be
present on the pipe surface.
Installation consists of the following steps:
1. Apply a thin coating of high temperature acoustic couplant to the
entire surface of the transducer face. The thickness of the
application should be approximately 1/16 inch (1.5 mm).
2. Install the two transducers following the procedures detailed in
the DTTN instructions on page 2.9 of this manual.
DTTS/DTTC Small Pipe Transducer Installation
The small pipe transducers are designed for specific pipe outside
diameters. Do not attempt to mount a DTTS or DTTC transducer
onto a pipe that is either too large or too small for the transducer.
Contact the Dynasonics factory to arrange for a replacement
transducer that is the correct size.
DTTS and DTTC installations consist of the following steps:
1. Apply a thin coating of silicone grease to both halves of the
transducer housing where the housing will contact the pipe. See
Figure 2.8.
