Schelt Technology

The HD33[L]M.2 data logger allows several physical quantities to be monitored in a largevariety of application fields:• Temperature• Relative humidity• Atmospheric pressure• Solar radiation• Rainfall quantity• Wind speed and directionIt has 5 inputs:• One input for relative humidity and temperature with NTC sensor combined probe or,alternatively, for temperature only probe with NTC sensor.• One input for pyranometer.• One input for rain gauge.• One input for cup anemometer.• One input for wind direction vane.It detects the atmospheric pressure by means of an optional internal sensor.If a relative humidity and temperature probe is connected, the dew point temperature iscalculated.Only one probe of each type can be connected. The probes are connected through M12connectors.On request, one of the inputs can be replaced by a 4...20 mA analog input for the connection ofa transmitter with current output, this allows the monitoring capability to be extended to manyother quantities in addition to the ones mentioned above (for example, a level sensor can beconnected).Thanks to GSM/GPRS transmission, the user will not have to remove the data logger from itsposition or reach the place where the data logger is installed to download the data measuredwith the PC: the instrument can send the data via e-mail or FTP and can upload the data onan HTTP server . You can alsomake 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 lowthreshold), the alarm hysteresis and a delay in the generation of the alarm. The overrun of thethresholds can be indicated by an audible signal of the data logger through an internal buzzer orsignaled by alarm e-mails or SMS messages.HD35AP-S PC software, downloadable free of charge from the Delta OHM website, allowsconfiguration of data logger, displaying measurements in real time both in graphical andnumerical 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 asolar panel through an appropriate optional power supply unit.IP 67 waterproof housing.Optional custom LCD display.

The outputs areactivated if the values measured by sensors connected to data loggers exceed the programmedthresholds. The data logger is able to store and report error conditions caused by malfunctionof the connected sensors, hardware or data logger during acquisition and storage. The alarmoutputs can also be programmed to detect such errors.The instrument is particularly suitable for use in weather stations, for the detection and remotetransmission of climatic variables. Delta Ohm manufactures a wide range of sensors formeasuring environmental variables that can be connected to the data logger, including sensorsfor measuring temperature, humidity, barometric pressure, wind speed, solar radiation,amount of rainfall, etc.The data logger can be supplied with a program of measures and stores pre-installed accordingto specifications of the customer, in order to be operational immediately after installation of thesystem. The program is installed directly from Delta Ohm to meet the required specificationswhen ordering. Some features of the data logger are password protected (Clock Setup, UserCode Setup, Send Program, GSM Setup). If needed the password is entered by the user at thetime of connection.Power supply from 12 to 30 Vdc. The system can also be powered by a solar panel and backupbattery of adequate capacity, allowing for installation in remote sites without electrical power.An internal lithium battery keeps the date and time of the instrument in the absence of externalpower. The data logger can provide power to all sensors connected at its terminals. It can signaland store when the supply voltage is below a programmable threshold and go into wait (standby)mode to low power consumption. In this mode, the datalogger interrupts the power supply toall sensors and suspends acquisitions/loggings, until the supply voltage returns at least to theminimum threshold.

The HD35ED… series of wireless data logging system consists of:

• One or more HD35ED… series devices: the HD35ED… devices acquire the values measured by the built-in sensors or by the external sensors connected by cable. The data are both stored in the internal memory of the device and transmitted via radio to the receiving unit (base unit/Access Point). Most HD35ED… devices are battery operated and do not require power connections.
• An HD35AP… base unit (Access Point): receives the measured values from all HD35ED… devices and transmits them to the PC. The HD35AP… base unit has an internal buffer battery with limited autonomy, so it must be powered from the outside by connecting it to the appropriate power supply (optional) or to the PC USB port.
• Software HD35AP-S: to be installed in the PC, it allows to download and visualize the data, to insert the data in a database and to configure the system.
  The software can be downloaded free of charge here.

XLOG-88E is a data logger cum Remote terminal device which can acquire data from AnalogInputs, Digital inputs, MODBUS RTU Clients devices and SDI12 client devices. It can also havedigital outputs which can be controlled remotely as well as on automated mode using simplelogic for automation. This logger logs collected data and can also communicate data to aremote server using FTP or HTTP protocol through GSM/GPRS or through Ethernet portconnected to a router.

The data loggers of the LR35… series are wireless devices for IoT (Internet of Things) applications that use LoRaWAN® technology for long distance data transmission.

LoRaWAN® technology uses the unlicensed frequencies of the ISM band (for example EU868, US915, AU915, KR920, AS923, IN865) and allows a transmission range of several kilometers depending on the installation position and the urbanization condition of the place where the network infrastructure is located, with extremely limited energy consumption, allowing long operation of battery-powered devices.

With the LR35… series, we provides a wide range of loggers with sensors for all general measurement conditions like temperature, humidity, differential pressure, CO2, PM.

For outdoor applications, we have specific IP67 loggers with connections to pyranometers, rain gauges and soil moisture.

But also we connect any other third party measurement with LoRa as long as it has a standard output: 4-20mA, 0-10V, Modbus-RTU.

HD50… is a data logger serie that supports Ethernet with RJ45 connector or Wi-Fi .

With the HD50 it is possible to start from 1 logger and extend it to a practically unlimited network of loggers. The HD50 settings can be opened from a web browser, as it has a built-in webserver. This way it is also possible to monitor the actual measurements.

Senseca already has the HD35 series, based on RF communication. In some cases when networks are very wide or complex or divided into more than 1 building, a mix of cabled, WiFi and Radio Frequency loggers can be the best solution. The HD50 series have the possibility to be integrated in such hybrid networks.

What benefits do this logger series have?

• Easy to use: it can be directly accessed by a web browser
• It can be used stand alone or in networks with hundreds of loggers
• Additional software for all solutions: database locally on PC, database on local server, cloud based
• Wide range of standard sensors (°C / UR / LUX / Atm / CO2/ differential pressure / PM1.0, PM2.5, PM4.0, PM10)
• It can support practically ‘any signal’: universal inputs make it possible to integrate any transmitter with standard output
• Optional software available for CFR21part11 (pharmaceutical market)
• The logger can send an email alarm when a value is higher or lower than the set threshold
