CHAPTER 2 Installing the Tag
16 Savi SensorTag ST-673 Installation Guide
◆ 3M Corporation conducted a longevity test of PST. They found no
significant degradation in the performance of PST even after five years
of service on a test vehicle. As long as the surface is prepared properly,
PST will work reliably for five years or longer.
◆ 3M Corporation compared the peel strength of a new roll of PST versus
a roll that had been aged 21 months. In all cases, the aged roll matched
performance of the new roll in tests conducted over a 72-hour period.
Achieving Maximum Communication
Savi SensorTag ST-673 achieves a 300-foot (91.44 meters) read range from
SR-410 and SR-650 fixed readers. To achieve the most consistent
communications with the tag, the fixed readers must be mounted:
◆ To have an unobstructed line of sight to the tag
◆ At 20 feet (6 meters) or higher
◆ With the reader dome pointed downward
The following photos show specific Savi SensorTag ST-673 mounting
locations that are based on the location of the humidity detection orifice.
