5. Vibration
- Mount the transmitter and sensor in a manner that minimizes vibration.
6. Accessibility
- When determining mounting location, consider future maintenance
and calibration requirements.
7. Avoid water
- Droplets adhering to the outer membrane of the sensor will reduce or
negate sensor performance. A rain shield is recommended for outdoor installations.
8. Avoid strong electromagnetic fields -
Mounting the gas transmitter near power
transformers or other strong EMI/RFI may cause undesirable results.
9. Avoid pressure and excessive air velocity -
GasPlus sensors are designed to
measure gas concentration under normal atmospheric conditions with up to 1 LPM air
flow. High air velocities will result in inaccurate measurement and reduce sensor life.
10. Conduit Seals -
Protect the transmitter electronics from moisture by thoroughly
sealing the conduit entries and tightening the cover of the transmitter housing.
11. Avoid PVC
– The Model 5000 Gas Transmitter enclosure and sensor housing are
made of the material Noryl.
Do not
allow this material to come in continuous contact with
PVC, as this will result in damage to the Noryl.

Physical Installation and Wiring
Installation of the Freedom™ 5000 System requires the physical mounting of the
enclosure (see Figure 5 & 6) and connection of the loop power (see Figure 7).
Please
take note of item 11 shown above.
The transmitter enclosure is provided with two ½”
FNPT fittings for mounting conduit. The Freedom™ 5000 is typically mounted one of
three ways:
1.
Wall or surface mounting with the use of the wall mounting bracket p/n 096-2618.
2.
Held in place with rigid conduit.
3.
“Table top” mounting with the use of the “L” bracket p/n 073-0213.
