107-L

Datalogger Considerations

One single-ended channel per probe is required; an excitation channel can be shared by several probes.

Installation Considerations

Air Temperature

When exposed to sunlight, the 107 must be housed in a radiation shield. It is typically housed in a 41303-5A 6-plate naturally aspirated shield. It may also be housed in a 41003-5 10-plate shield if a 41322 Adapter Plate is used. The radiation shield mounts to a mast, tower leg, or crossarm.

Soil Temperature

The 107 is suitable for shallow burial only. Placement of the cable inside a rugged conduit may be advisable for long cable runs—especially in locations subject to digging, mowing, traffic, use of power tools, or lightning strikes.

Water Temperature

The 107 can be submerged to 50 ft. Please note that the probe is not weighted. Therefore, the installer should either add a weighting system or secure the probe to a fixed, submerged object, such as a piling.

Multiplexers

To measure large numbers of probes, the AM16/32B multiplexer is recommended.
