Teknik Bilgi

Power supply If the rechargeable battery is used: 18…30 Vdc If the rechargeable battery is not used: 7…30 Vdc without ETHERNET module 12…30 Vdc with ETHERNET module Power consumption @ 12 Vdc < 3 mA without ETHERNET module and with no GSM/3G activity ∼ 200 mA with ETHERNET module and with no GSM/3G activity < 1 A peak during GSM/3G activity Battery Optional internal lead 12 V / 3.4 Ah. Maximum charge current 1 A. The autonomy depends on the number and type of sensors connected. Switched power supply output If the data logger is powered by a solar panel (+Vpanel input), the output is equal to the voltage of the internal lead battery (nominal 12 V). If the data logger is powered by the +Vdc input, the output is equal to the voltage of the +Vdc input. The output is active only when the external sensors have to be powered. Antenna External Measuring interval 1, 2, 5, 10, 15, 30 s / 1, 2, 5, 10, 15, 30, 60 min Logging 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. Number of samples: from 242,850 to 858,070 depending on the number of detected quantities. Alarm Sending of alarm e-mail and SMS. Two voltage-free normally open (NO) contact alarm outputs. Max 300 mA @ 30 Vdc resistive charge. Display Optional custom LCD LED indicator 2-color LED: power on (blinks red), GSM/3G activity (blinks green) Connection to PC USB port with mini-USB connector ETHERNET connection RJ45 connector (only if the optional ETHERNET module is present) Internal clock drift ± 2 ppm (0…+40 °C) / ± 5 ppm (-40…+70 °C) Operating conditions -40…+70 °C / 0…100 %RH for the version without LCD -20…+70 °C / 0…100 %RH for the version with LCD Weight 1 kg approx. Housing Dimensions: 270 x 170 x 110 mm (excluding external antenna) Material: Polycarbonate (PC) Protection degree: IP 65 (with protective cap on the USB connector) Installation Fixing to a 40 mm diameter mast. Measurement characteristics: Temperature (instrument in line with the probe HP3517WTC… or TP350NTC…) Sensor NTC 10 kΩ @ 25 °C Measuring range -40…+105 °C Resolution (of instrument) 0.1°C Accuracy ± 0.3°C in the range 0…+70°C / ± 0.4°C outside Stability 0.1 °C / year Relative Humidity (instrument in line with the probe HP3517WTC …) Sensor Capacitive Measuring range 0…100 %RH Resolution (of instrument) 0.1 % Accuracy ± 1.8%RH (0…85%RH) / ± 2.5%RH (85…100%RH) @ T=15…35 °C ± (2 + 1.5% measure)% @ T=remaining range Sensor operating temperature -40…+80 °C Response time T90 < 20 s (air speed = 2 m/s, without filter) Temperature drift ±2% over the whole operation temperature range Stability 1% / year
