Publication GMSI10-UM028A-EN-E - November 2007
Installation
Follow the steps below to install the Dual Probe Holder. Refer to Figures on pages 3 and 4
for assistance. Make sure the machine is stopped before installing the Dual Probe Holder.
Prepare Mounting Surface
1. Spot face the surface, then drill and tap a hole in the machine case where you want to
install the Dual Probe Holder.
Check Parts and (if necessary) Replace Housing and Stinger O-rings
2. Open the Dual Probe Housing cover and remove plastic bag containing adjusting
cage, adjusting knob, jam nut and o-rings.
3. Replace the installed housing and stinger Viton O-rings with Buna O-rings (supplied
in plastic bag) to meet low temperature operating conditions (see table below). If you
do not need to replace the o-rings, proceed to step 4. Figure 3 on page 8 shows the
placement of the o-rings.
The table below shows the required o-rings for the appropriate temperature operating
ranges.
TIP
Follow API 670 requirements for surface finish and flatness, even for
non-API installations. If the surface is not properly prepared, it can reduce
the detection of higher frequencies.
Table 2 O-Ring Requirements
Temperature Operating Range Required O-ring
-10 to 400°F (-23 to 204°C) Viton O-ring (default)
-30 to 230°F (-34 to 110°C) Buna O-ring
