The HD33[L]M-MB.2 data logger allows several physical quantities to be monitored in a large variety of application fields. To the “Master” RS485 MODBUS-RTU input you can connect a network of sensors for measuring, for example, temperature, humidity, atmospheric pressure, solar radiation, wind speed and direction, etc. As an alternative to the Modbus-RTU protocol, a proprietary protocol can be used to connect the HD2003 anemometer. A voltage-free contact input allows connecting a rain gauge with contact output. The contact can be configured as normally closed or normally open. A measurement compensation curve as a function of the rainfall rate can be configured. The data logger calculates the rainfall rate in mm/h (by referring the rainfall quantity in the last five minutes to an hourly value) and the rainfall quantity in the last day. If a relative humidity and temperature probe is connected, the dew point temperature is calculated. If a pyranometer is connected, the daily Wh/m2 (Wh = watt hour) are calculated.
Thanks to GSM/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 (for example the Delta OHM portal “www.deltaohm.cloud”). You can also make a direct GPRS TCP/IP connection with a remote PC which has an Internet connection. The data logger GSM functions can be remotely controlled by sending SMS messages. For each detected quantity, the user can set two alarm thresholds (high threshold and low threshold), the alarm hysteresis and a delay in the generation of the alarm. The overrun of the thresholds can be indicated by an audible signal of the data logger through an internal buzzer or signaled by alarm e-mails or SMS messages.
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 data logger operates with 7…30 Vdc direct power supply voltage and can be powered by a solar panel through an appropriate optional power supply unit. It is equipped with a switched power supply output to power the sensors only when the measurement has to be carried out. The power output, when enabled, has the same value as the power input. IP 67 waterproof housing. Optional custom LCD display
