Industrial Data Loggers

What is an Industrial Data Logger?

An industrial data logging system comprises of a monitoring and data acquisition device and one or more sensors connected to the device. The device automatically records and stores data from the sensors allowing it to be accessed remotely using an appropriate communications protocol. Typical applications include the monitoring power & energy, environmental and process parameters, collecting data on voltage (V), current (I), frequency (Hz), power (kVA and kW), power factor and energy usage (kW), temperature and humidity, power outages and process faults. The data collected can be accessed using an appropriate communications protocol and then validated, documented, measured and analysed over specific time periods.

Perseus Remote Energy Monitoring and Data Concentrators (up to 100 Meters, 1000 Variables)

The Perseus Energy 240 is a device designed to connect to HW group and third-party sensors (via Modbus/RTU) and connects to the Sensdesk portal. The Perseus Energy can be used as a Modbus/RTU to Modbus/TCP gateway. The device supports up to 100 energy meters (electricity, gas, water, with up to 1000 variables and can read values from other network devices via SNMP, Modbus/TCP, MQTT, BACnet, and XML. The Perseus 240 can also analyse metered data for local alarms, conditions and actions, and execute LUA scripts. The device is a gateway with no RJ-11 ports or Digital Inputs (DI).

The Perseus Energy 242 can collect data from external sensors, detectors and meters and report this over a physical LAN connection and connects to the Sensdesk portal. The device can monitor local conditions and execute LUA scrips and has a calendar and periodic scheduler. Perseus 242 has M-Bus Master, and can connect up to 100 meters with up to 1000 variables and also connect to external physical sensors for temperature (°C), relative humidity (%RH), Amps (A) and Voltage (V), and has detectors (relay/dry contacts) and a WLD (Water Leakage Detection) cable port. Third party sensors can also be connected to the device via LAN or Modbus/RTU. Email or SNMP Trap alerts can be sent from the device with measured values also available via a universal Open API (SNMP, Modbus/TCP, MQTT, BACnet, and XML). The Meters API also means that the Perseus 242 can read over a local area network connection, sensor values from other compatible devices from HW group for data for analysis or alarm reporting.

The Perseus Energy 285 is a DIN rail LAN and LTE solution for remote energy monitoring and control applications with M-Bus Master and connects to the Sensdesk portal for a quick and easy view dashboard. Additional physical sensors can be connected to the device, for example to record analog inputs for temperature monitoring (°C), relative humidity data (%RH), Amps (A) and Voltage (V) and the Pereus 285 also has detectors (relay/dry contacts) and a WLD (Water Leakage Detection) cable port. The Meters API also means that the Perseus 285 can also read over a LAN connection, sensor values from other compatible devices from HW group for data for analysis or alarm reporting. Third-party meters (sensors) can also be connected via directly via Modbus/RTU. LTE mobile backup connectivity allows the product to stay operational in case of an Ethernet outage with alerts reported via SMS, phone calls, email or SNMP Traps. Measured values are also available via an Open API (SNMP, Modbus/TCP, MQTT, BACnet, and XML). The Perseus 285 has a digital input and four digital output channels.

Damocles and Poseidon2 Data Loggers

The Poseidon2 and Damocles2 data loggers have a built-in interface for IP/Ethernet communications and can be used in Industrial Internet of Things (IIoT) solutions. The interface allows real time and stored data to be accessed and transmitted using the HWg-Push protocol to an appropriate master station such as the Sensdesk cloud-base portal or third-party systems via the MQTT IO protocol. Data can also be emailed to HWg-PDMS software, where it will be download from a POP3 mailbox or its secured POP3S variant.

The SensDesk portal provides quick dashboard reviews over an HTTPS connection, including mobile devices and can display graphics for up to 3months of measured values. The portal also allows alarm messages to be configured for sending via email or SMS text.

The HWg-PDMS software can be used to collect the measured data and export this to a Microsoft Excel file format for further analysis and inclusion in reports for industry related authorities as in the pharmaceutical and food processing industries.

The IoT protocol MQTT can also be used to collect data from Poseidon2 and Damocles2 devices via IoT portals set up on Microsoft Azure and similar packages. The MQTT portal allows data logged by the devices to be reported in a cloud portal with data from third-party devices for a comprehensive overview and data logging project.
