Technical Shortform LOG-PT1000(-30) Wireless Temperature Data Logger

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!
Soil
Fabric (optional)
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.

Technical Data
Logger:
Temperature range: -40°C to +85°C. Radio transmission frequency: a) EC,
parts of Africa and Asia): 433.92 MHz (harmonised frequency for license free
operation within the EC, Switzerland, Norway, Iceland. (for other countries
please check the local regulations. b) USA/Canada: 905 MHz. Effective
emitted energy < 5mW
Memory:
2048kB (non volatile) Flash memory. Up to 400.000 measures: 1 measure
typically uses 5.5 Bytes (Software Version 1.1, will be reduced to 2-3 Bytes in
a following revision). Each HK-record (time stamp and optional HK-data)
typically requires another 6 to 9 bytes. Since HK-values are recorded only
after a selectable number of measures, (factory default is 6).
Example: 24 measures per day require 24*5.5 = 132 Bytes. Additionally 4
HK-records require additional 4 * 9 = 36 Bytes. Sum: 168 Bytes. Conclusion:
2048kB will be good for abt. 32 years (theroetically) without clearing the
memory. The memory has a duty cycle of >100 000 clearing cycles.
HK-data:
Internally the battery voltage and internal temperature can be recorded. The
internal temperature is only calibrated on demand. Calibrated accuracy is +/1°C in the range -20°C to +40°C. The battery voltage is measured with a
resolution of 1 mV.
Sensor:
„PT1000 1/3 DIN“: Platinum based temperature sensor, accuracy at 0°C: +/0.1°C. Internal resolution: 0.01°C. Range: -90°C to +90°C. Typical accuracy <
+/- 0.2°C in the range -20°C to +40°C. Long term stability: < +/- 0.02°C /
year. The sensor is connected in 4-wire technology. Sensor cable possible
from 20 cm to 1 meter, factory default is 20 cm. Cable: PUR (Polyurethane)
.Sensor cover: POM or optional Stainless Steel. Optional Sensor with
Connector: „Hirschmann M8, IP68“. Sensor: Male, Logger: Female.
Battery:
SB-AA11 from www.vitzrocell.com :
3.6 Volt Lithium (Li-SoCl2), 2400mAh.
Max. Pulse load: <20 mA
Size: AA with solder terminal
Low self discharge rate (less than 1% after 1 year of storage at +20“C)
Non flammable
Non restricted for transport
The battery can be replaced by the user. Similar types of battery are available
from all major battery production companies. A word about the battery
voltage: The voltage is around 3.4-3.6 V at 20°C, but „drops down“ to
3.1-3.3°C at -40°C. The battery voltage does not significantly reflect the
remaining power of the battery, the „temperature drops“ show this better.

Calculation the battery capacity
4 main factors impact the battery capacity/lifetime:

 Constant load: about 10µA for the current version Mode „Sleeping“ with
periodically checking the radio. So 1 mAh is good for ca. 100 hours of „Sleeping“

 Pulse load: about 9mA for 0.2 seconds per measure, so 1 mAh is good for
ca. 2000 measures

 Self discharge: about 10% after 10 years

 Temperature cycles: difficult to predict, could be up to 50% (worst case)
As a rough estimation: Theoretically 2400 mAh are good for >25 years of „Sleeping“ or
>4000000 measures (this is almost 500 years for 1 measure per hour), if no self discharge is
assumed. Practically we normally calculate only with 1/3 of the capacity (the rest is for
spare): For 1 measure per hour each year requires 5 mAh, with the rest of 2400 mAh / 3 =
800 mAh still almost 8 years of operation should be possible. Hence we would recommend to
replace the battery with these settings after 5 years or later, if „temperature drops“ for cold
phases rises significantly.
Compliance informations (only for USA/Canada):
a) User Information according to FCC 15.21:
Changes or modifications not expressly approved by the party responsible for compliance could void the user’s
authority to operate the equipment.
