Tag Placement
Tag Placement
Savi Technology requires that you mount Savi SensorTag ST-673 by
inserting the tag and supplied metal mounting sleeve through the humidity
detection orifice on the jet engine container. You use the pressure sensitive
tape (PST) to reinforce the tag and sleeve to the engine container.
PST Reliability and Durability
The only brand of PST that Savi Technology recommends for mounting
SaviTags is 3M Corporation’s Automotive Acrylic Plus Attachment Tape.
For ease of installation, during manufacturing Savi installs this PST on the
back of the mounting sleeve. PST mounting kits are also available for
separate purchase.
Once a mounting sleeve is fastened to an asset, you can leave it on the asset
even after Savi SensorTag ST-673 is removed so it is available for future
use with other compatible SaviTags. Prior to re-use, visually inspect the
PST-mounted sleeve to make sure it is attached securely. If necessary,
reinstall the sleeve using new PST.
3M Corporation has conducted extensive environmental testing on their
Automotive Acrylic Plus Attachment Tape. In addition, Savi has conducted
its own independent environmental tests of PST. The U.S. Army
(Tobyhanna Army Depot) has also tested PST for use on surfaces treated
with Chemical Agent Resistant Coating (CARC). All these tests confirm
that PST is an appropriate choice for mounting SaviTags.
◆
Savi Technology successfully conducted the following tests upon
samples of 3M PST:
Extreme temperature -40ºC to +158ºF (–40º to +70º Celsius)
❖ Step test (200 pounds applied in shear)
❖ Shock (140g or 120 lbs.)
❖ Vibration (MIL-STD-810E)
❖ Salt fog (MIL-STD-810E)
❖ Corrosive liquids
❖ Peel test (50 pounds of peel force)
Savi’s tests confirm the adhesion integrity and reliability of 3M PST.

CHAPTER
Installing the Tag
◆
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.

Mounting Savi SensorTag ST-673
The mounting method for Savi SensorTag ST-673 includes using pressure
sensitive tape, screws, and a metal mounting sleeve. This method prevents
accidental loss of the tag by sudden impact, vibration, or shock during
transport.
Savi SensorTag ST-673 includes these required mounting fasteners:
◆ Stainless steel screws and washers
◆ PST
◆ Metal mounting sleeve
