TECHNICAL CHARACTERISTICS OF DATA LOGGERS IN WATERPROOF HOUSING
Transmission frequency 868 MHz, 902-928 MHz or 915.9-929.7 MHz according to the model
Antenna Internal (default). On request, external fixed or with 3 m cable.
Transmission range
In open field:
300 m (E, J)/ 180 m (U) with internal antenna towards base unit (except
HD35APD) and repeaters.
180 m (E, U) with internal antenna towards base unit HD35APD.
> 500 m (E, J, U) with external antenna towards base unit (except
HD35APD) and repeaters.
180 m (E, U) with external antenna towards base unit HD35APD.
(could be reduced in presence of obstacles or adverse atmospheric
conditions)
Measuring interval
(*)
1, 2, 5, 10, 15, 30 s / 1, 2, 5, 10, 15, 30, 60 min
Logging and
transmission interval
(*)
1, 2, 5, 10, 15, 30 s / 1, 2, 5, 10, 15, 30, 60 min
Internal memory Circular management or stop logging if memory is full.
The number of storable samples depends on the number of detected
quantities (see table 9.10.1).
Alarm Acoustic through internal buzzer
Display Optional custom LCD
Buttons Connection button inside the instrument
LED indicators RF communication status. Models without LCD have alarm and battery
level LEDs.
Power supply Non rechargeable lithium thyonil chloride (Li-SOCl
2
) internal battery, 3.6
V, size A (size C for HD35EDWK/4TC, HD35EDWS/xTC and HD35EDWH),
2-pole Molex 5264 connector. Optional 24 Vac/dc power supply.
7…30 Vdc external power supply (without internal battery) for HD35EDWPTC-
ALM, HD35EDW-MB and the models with CO
2
probe.
Battery life
(without repeaters,
direct communication
with HD35AP...)
4 years typical for HD35EDWK/4 and HD35EDWH models (with 10 s meas-
urement interval and 30 s logging interval);
2 years typical for the other models, with 5 s measurement interval (10 s
for HD35EDW7P/...TC, HD35EDW14bNTC, HD35EDW14b7PTC,
HD35EDWWBGT) and 30 s logging interval.
Operating temperature
and humidity
-20…+70 °C / 0…100 %RH
