Unidata Neon - Model M Series -Remote Logger

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/3006M Neon Remote Loggers utilise different wireless networks as their method of sending sensor data from the field to the Neon Server for example 3004MC and 3006MC uses cellular 2G, 3G, 4G or LTE phone network while 3004ME and 3006M uses Ethernet network.

3004ML 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.

3004MH and 3006MH – Microsatellite datalogger makesuse of a microsatellite network as their 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.

3004MI and 3006MI – Iridium SBD  datalogger take 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 and 3006M 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 Nano Logger was designed for use in boreholes of 100mm internal diameter and above but it can be used whenever a smaller form factor is logger is required. It can be configured to use ether Cellular, Iridium SBD or LoRa networks as its method of sending sensor data from the field to the Neon Server.

The 3001M Nano 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, LoRa or Satellite network.

The 3001M Nano 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 3001M NRL Nano Logger comes with 2 x D cell Lithium batteries.

The 3901A Battery extender 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.
