Neon Remote Logger – M Series

  • Overview

    Four Channel M Series Neon Remote Loggers are smaller form factor NRL dataloggers, housed in a polycarbonate case.

    The 3004M Neon Remote Logger connects to sensors in the field, collects readings from those sensors, logs the sensor data, provides control functions and also transmits the collected data to a central server. The 3004M Neon Remote Logger is programmed in the field with a Unidata standard program called a scheme. The scheme specifies how often and for how long the datalogger should collect data from the sensors and how often the data should be sent to the server. Control outputs are also set up in the scheme by setting up custom events.

    A wide range of sensor types are supported, for example, analog; including 4-20mA sensors, frequency counters, digital inputs as well as Modbus and SDI-12. Control of external equipment (such as triggering a relay when a user defined event occurs, or initiating a shutdown), can be accomplished via Open Drain FET output. Sensors are connected to the logger via pluggable terminal blocks, allowing for easy removal of the logger if servicing is required.

    The 3004M Neon Remote Loggers utilise different wireless networks as their method of sending sensor data from the field to the Neon Server for example 3004MC uses cellular 2G, 3G, 4G or LTE phone network while 3004ME uses Ethernet network.

    3004 ML LoRa WAN datalogger utilises the LoRa communication system, LoRa WAN network, which utilises MQTT as its method of sending sensor data from the field to the Neon Server. The NRL LoRa operates in what Unidata calls LoRa Mode 2. In this mode, sensors are read by the logger according to the scheme. A set of short data packets will be sent, as set by logging interval, to the LoRa WAN gateway over either private or public LoRa network. LoRa WAN gateway transfers data packets to Neon Server using Ethernet, cellular or satellite network. The LoRa Wan system has a typical range of to 5 Km, the range reduces in built up areas depending on building density and increases where there is line of sight and with use of a larger antenna.

    3004 MH – Microsatellite datalogger makes use of a microsatellite network as its method of sending sensor data from the field to the Neon Server. The microsatellite network is a message based system, providing low cost satellite communications over a high latency service. This low cost service is ideal if you have a requirement for occasional short messages to report sensor data, when the latency of the messages is not very important. Latency from such systems is in the order of hours and the very low satellite airtime costs reflect this high latency service.

    3004 MI – Iridium SBD  datalogger takes advantage of the high reliability Iridium satellite network short burst data subsystem. It is a high reliability message based system, providing reasonable cost satellite communications and a low latency. This service is ideal if you have a requirement for short messages to report sensor data. Latency from such systems is in the order of minutes and the satellite airtime costs reflect this low latency service.

    Any Neon Remote Logger from 3004M range can be housed in an aluminium IP68 rated enclosure. When high standard water protection is required, Unidata M series Neon Remote Loggers can be housed in a rugged die cast IP68 rated aluminium enclosure. Selected enclosure satisfies the requirements of IEC60529 IP68 conditions – being submerged under more than 1m of water for 24 hours without any water ingress.

    Enclosure is powder coated for extra corrosion protection and equipped with a circular 8 way IP68 stainless steel connector. Matching IP68 stainless steel connector is either assembled onto sensor, if available, or provided for customer to use.

    The 3001M Borehole Logger is a Neon Remote Logger that is designed for use in boreholes of 100mm internal diameter and above. It can be configured to use ether Cellular, Ethernet, Iridium SBD, LoRa, or Microsatellite networks as its method of sending sensor data from the field to the Neon Server.

    The 3001M Borehole Logger connects to sensors in the field, collects readings from those sensors, logs the sensor data and transmits the collected data to a central server via a Cellular, Ethernet, LoRa or Satellite network.
    The 3001M Borehole Logger is programmed in the field with a Unidata standard program called a scheme. The scheme specifies how often and for how long the datalogger should collect data from the sensors and how often the data should be sent to the server. A wide range of sensor types are supported, for example, analog sensor, frequency counter, digital input as well as Modbus and SDI-12.

    The 3004 Neon Remote Logger

    The 3001M NRL Borehole Logger comes with 2 x D cell Lithium batteries.
    The 6909D Battery extender is a battery extender which can be used to add additional lithium battery capacity to the 3001 Neon Remote Logger. Depending on the application, the scan rate, the log rate and the communications rate, this battery extender allows for up to 10 years of operation for the 3001 NRL.
    Sensors are connected to the logger via a custom specified connector, allowing for easy removal of the logger if servicing is required.
