– Weld Pocket Detail
Add 2 or 3 welds to each of the four secondary weld pockets A thru D. These welds do not need to follow
any specific sequence. These welds provide additional strain relief to prevent tension on the cable from
disturbing the gage.
Gage Protection:
To ensure reliable gage operation, the gage must be protected from physical damage, moisture, and corrosion of the
substrate near the gage installation sight. As described in the
Surface Preparation
section, a rectangular area 6 x 10
inches [150 x 250mm] should be prepared to (SSPC-SP10 / NACE 2) prior to installing the gage as shown in Figure
6. It is important that this area be free from all paint, rust, scale, oil, and grease. This will allow the gage protection
material to bond to bare metal and provide a robust seal against the elements.
Micron Optics recommends the following accessories for use in aboveground installations on steel structures. In
many applications, additional testing may be required to determine if additional sensor protection is required.
Sensor Accessories:
os315X Weatherproofing Kit
os315X Protective Cover & Insulation Kit
Universal Connector Protection Fitting “PF” Kit
The os315X Weatherproofing Kit contains the following parts:
STOPAQ:
WrappingBand EZ (precut 100 x 190mm patch)
STOPAQ:
Paste CZH
Kapton® Polyimide tape, 25mm wide, .09mm thick
The following procedure is recommended for typical installations:
