LOG-PT1000(-30) Wireless Temperature Data Logger
Handling
The logger consists of the electronics (housing: POM plastic, 20x160 mm) and the Sensor
(Standards: 0 cm (LOG-PT1000) and 30 cm (LOG-PT1000-30)
If the enclosure must be opened (e.g. for battery replacement), please check the o-ring
(sealing) very carefully! Use lubricant (to protect the o-ring) before reassembling.
We recommend to lubricate the enclosure additionally after reassembling and before using in
the field (e.g. by Spray Vaseline). Please ensure, that no force affects the connector
sensor<->logger in the field.
If required (as additional protection against smut), we
recommend to use a small piece of fabric (like cotton) to
cover the enclosure before putting under the soil. Do not
cover the enclosure with plastic material, because of the
risk of accumulating liquid water!
About the range: Optimal range (line of sight in open
environment) could be up to 300 meters for loggers with
separate antennas. If the sensor cable (like here) is used as antenna, a range of 100 meters is
realistic. In this case the first 20 cm of the sensor cable are mostly important for the
transmission. Hence in the picture on the right (a logger under soil) the cable is routed as a
loop. Normally depths of 20-30 cm still allow a range of 10-30 meters. On request, special
beam antennas with very high gain are available from us.
Please note: The devices are available with several different radio frequencies, depending on
the local regulations of the country (e.g.: 433 MHz in Europe, parts of Africa and Asia, 905
MHz in USA and Canada, ...). It is in the responsibility of the user, not to use devices that are
not allowed in the country of usage.
