3.1 Installing the Dampening Material, Transducers and Fixtures
Since the PT878GC is specifically designed for gas measurement with clamp-on transducers, it requires the use of
specially designed fixtures and dampening material to maintain the highest possible measurement accuracy.
Panametrics Sensing supplies the CFG series of fixtures:
•
The V1 clamping fixture for pipes with diameters between
0.75 and 1.25 in. (20 to 30 mm).
• The V4 clamping fixture for pipes with diameters between
1.25 and 4 in. (30 to 100 mm).
• The V8 clamping fixture for pipes from 4 to 8 in. (100 to
200 mm).
• The V12 clamping fixture for pipes from 8 to 12 in. (200 to
300 mm).
• The PI clamping fixture for pipes from 12 to 24 in. (300 to
600 mm).
Figure 10 on the next page illustrates the V series and PI fixture assemblies. Complete the steps in the following
sections to position and install the transducers, fixtures and dampening material.
