TWTG NEON Temperature Transmitter

TWTG NEON

NEON Product Introduction
NEON stands for a standardized approach to collecting data points from the operational environment and in doing so, creates a general approach to integrated data collection within existing IT ecosystems.

The TWTG NEON product range supports all industrial customers moving towards LoRaWAN as the Industrial IoT network of the future. The LoRaWAN network gives industrial operations a secure solution, which scales up to tens of thousands of sensors, covers complete sites with only a small amount of gateways and best of all – the low-power approach means that the lifetime of the NEON products is extended dramatically.

Mounting Bracket Dimensions

Installation Methods

Installation using mounting holes
Place the bracket against the (flat) desired surface and use the screw holes or slots to fix in place. Note: Slots and screw holes are designed for M4 fasteners.

Installation using threaded holes

Note: Threaded hole accepts M5 bolts.

Installation using band clamp
The Neon Temperature Transmitter can be mounted to a pole using a 14 mm wide band clamp, other sizes are not recommended.

Procedure:

1. Place the band clamp through the bracket;
2. Place the band clamp around the pole and cut to size;
3. Place the band clamp through the adjustable tightener and fold around the bottom with a plier;
4.  Place the band clamp around the pole with the (adjustable) tightener and fix it in place.

Using the Temperature Transmitter with Thermocouples

Cold Junction Compensation
The interface to the NEON Temperature Transmitter uses an M12 connector with Type-A polarisation. This interface can be used for reading out both thermocouples and RTDs. For use with thermocouples the Temperature Transmitter has a built-in cold junction compensation (CJC):

The temperature transmitter uses the copper pins of the M12 connector as the cold junction, as seen in figure 12. CJC Section Overview. The cold junction compensation uses the temperature of the copper contacts as measured by the internal reference temperature sensor. The internal reference temperature is directly in thermal contact with the cold junction.

Assessed Connectors
The following connectors have been assessed by TWTG and can be used in combination with the Neon Transmitter:

Selecting a thermocouple wire
A suitable thermocouple wire needs to be assessed as simple apparatus and needs to be assessed as safe with regards to thermal and spark ignition. Select a cable with cross section of 0.14mm2 to 0.75mm2 with a round outer shell with a diameter of 4 to 8 mm. If the sensor is mounted in a noisy environment a shielded cable can be used.

WARNING

• Do not connect the shield to the M12 connector shield to prevent a multi-point ground, only connect the shield at the thermocouple junction.

Use the values as listed in table 8 to determine compliance. The maximum permitted cable length is determined by cable Li and Ci and limited to the maximum installation cable length of 3 meters.

between 0 meter and required cable length

Product Functionalities

A detailed description of setting-up communication and configuring device settings can be found in “Communication protocol”, refer to table 1. Related documents.

Application Event Message
The temperature transmitter measures and reports the temperature either by set intervals (a timer-based trigger) or a condition-based trigger.

Event-triggers
Event messages are triggered on one of the following triggers.

• Timer (periodic):
  The timer trigger is configurable through the following configurations:

  • temperature_measurement_interval_seconds
    Interval in seconds, at which the temperature sensor is read.

  • periodic_event_message_interval
    Interval in the number of measurements at which the application event messages are periodically sent. The periodic counter is reset on every event message.

• Condition:
  A condition-based trigger can be either of the following triggers:

  • Above
    If the maximum temperature is above the temperature_threshold then the condition is true. A transition of the condition from false to true or true to false will trigger an event message.

  • Below
    If the minimum temperature is below the temperature_threshold then the condition is true. A transition of the condition from false to true or true to false will trigger an event message.

  • Increasing
    The condition is true when the current temperature is at least temperature_threshold higher than the minimum temperature in the measurement_window (The maximum number of measurements to observe delta temperature to trigger an event). A transition of the condition from false to true or true to false will trigger an event message.

  • Decreasing
    The condition is true when the current temperature is at least temperature_threshold lower than the maximum temperature in the measurement_window (The maximum number of measurements to observe delta temperature to trigger an event). A transition of the condition from false to true or true to false will trigger an event message.

Content application event message

• Temperature
  The connected sensor temperature in units of 0.1 °C:

  • Maximal;
  • Average;
  • Minimal.

• Trigger
  Source of the trigger for the application event message:

  • “timer” (0);
  • “condition_0” (1);
  • “condition_1” (2);
  • “condition_2” (3);
  • “condition_3” (4).

• condition_n
  The current state of each condition.

Device Status
Besides reporting the application temperature as discussed previously, the Temperature Transmitter also reports on the device status itself. This is done through a device status messages. A device status message is sent periodically and includes a range of device health parameters, including the following:

• event_counter;
• battery_voltage;
• PCB temperature;
• tx_counter;
• avg_rssi;
• avg_snr.

See “Communication Protocol” in Related documents for a detailed explanation.

Default Configuration
The Temperature Transmitter is delivered with a default configuration. The default configuration includes:

• Measurement interval of 15 mins;
• The event-based message at the time of each periodic trigger with an interval of 15 measurements. (15 * 15 = 225 mins);
• Device status message interval of 24 hours;
• Enabled confirmation messages on all messages.

See “Communication Protocol” in Related documents for a detailed explanation of all default configuration values.
