The HD33[L]MT.4 data logger is specifically designed for use in weather stations. Many types of sensors can be connected thanks to its standard terminal header inputs. The data logger is equipped with:
  • 4 analog independently configurable inputs (0…50 mV, -50…+50 mV, 0…1 V, 0…10 V, 0…20 mA or 4…20 mA, Pt100, Pt1000, thermocouple, potentiometer, pyrgeometer).
  • 2 voltage-free counting contact inputs (e.g. a tipping bucket rain gauge and a cup anemometer can be connected).
  • One RS485 port with Modbus TCP/IP (via an optional module for the connection to an ETHERNET network) or Modbus-RTU protocol, configurable as "Master" or "Slave".
  • One SDI-12 “Master” port compatible with version 1.3 of SDI-12 protocol.
  • 2 voltage-free contact alarm outputs.
  • On request, input with M12 connector for relative humidity and temperature with NTC sensor
  • combined probe or, alternatively, for temperature only probe with NTC sensor. 
Optional custom LCD display.
Thanks to 4G / 3G / GSM(2G) / GPRS transmission, the user will not have to remove the data logger from its position or reach the place where the data logger is installed to download the data measured with the PC: the instrument can send the data via e-mail or FTP and can upload the data on an HTTP server (Cloud, for example the Delta OHM portal “www.deltaohm.cloud”). The data logger can be controlled remotely either by sending commands via SMS messages or by establishing a direct TCP/IP connection via mobile network with a remote PC connected to the Internet. For each detected quantity, the user can set two alarm thresholds (high threshold and lowthreshold), the alarm hysteresis and a delay in the generation of the alarm. The overrun of the thresholds can be signaled by alarm e-mails or SMS messages. Two voltage-free contact alarm outputs are also available.

HD35AP-S PC software, downloadable free of charge from the Delta OHM website, allows configuration of data logger, displaying measurements in real time both in graphical and numerical format, data download. The data transferred to the PC are entered into a database. The internal clock of the data logger has high accuracy and is extremely stable in the whole operating temperature range of the instrument. It supports the automatic time synchronization with an HTTP reference server.

The optional 12 V / 3.4 Ah rechargeable backup battery to be installed inside the case prevents the loss of recordings in case of no external power supply. The battery charger is integrated in the instrument. The data logger can be powered by a solar panel and is designed to be low power: can operate for weeks even in absence of battery recharging from the solar panel. Power supply 18…30 Vdc if the rechargeable battery is used or 7…30 Vdc (without ETHERNET module) / 12…30 Vdc (with ETHERNET module) if the rechargeable battery is not used.

A switched power supply output allows powering the sensors only when measurements have to be taken. IP 65 housing. 

  • Possibility of connecting many sensor types thanks to the 4 analog inputs, the 2 contact inputs and the RS485 MODBSU-RTU and SDI-12 digital inputs
  • 4G/3G/GSM(2G)/GPRS module for remote monitoring
  • Sending of data via e-mail, FTP and to an HTTP server (for example the Delta OHM Cloud)
  • Configurable as Master or Slave MODBUS unit
  • Connection to ETHERNET network with MODBUS TCP/IP protocol through optional module
  • PC software for configuration, monitor and data download in a database
  • Software option available for compliance to FDA 21 CFR part 11 recommendations
  • 2 contact alarm outputs and alarm notification via e-mail and SMS when configurable measurement thresholds are exceeded
  • IP 65 housing
  • Optinal custom LCD
  • It can be powered by mains (with optional external power supply unit) or by a solar panel
  • Low power, it can operate for weeks even in absence of recharging of the internal battery
  • Internal clock of high accuracy and stability, with possibility of automatic time synchronization with an HTTP or NTP reference server

  • 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: 
  • < 4 mA without ETHERNET module and with no mobile network activity
  • ∼ 200 mA with ETHERNET module and with no mobile network activity
  • < 1 A peak during mobile network 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.
