IMI TWTG
NEON Temperature Transmitter (Ex)
Transmitter for industrial temperature monitoring, designed to connect directly to thermocouples and deliver precise, near real-time data from critical assets.
Direct thermocouple integration enables accurate measurement of extreme temperatures, supporting a wide range of industrial processes.
LoRaWAN wireless connectivity allows for remote data transmission and easy deployment across large or hard-to-access sites.
Engineered for reliability with a robust enclosure, up to 10 years of battery life, and optional IECEx / ATEX Zone 0 certification for safe use in hazardous areas.
Features
Knowledge is the basis of good decision making. The NEON Temperature Transmitter is designed to be implemented within minutes and to transmit the signal for monitoring purposes by being connected to an industrial thermocouple or RTD.
The device can be connected to a thermocouple via an M12 connector with an up to three-meter-long extension cable. It uses on-board intelligence to determine average values over user-determined time scales to provide insights that can be used directly within existing systems.
The NEON Temperature Transmitter and thermocouple assembly can be installed on existing assets and monitors changes or absolute extremes in temperature. By monitoring these in a variety of locations, insights can positively benefit operations. With the industrial thermocouple or RTD connected, extremely low temperatures can be measured, such as hydrogen or high temperatures that are found within furnaces, and everything in between. As a standard, the NEON Temperature Transmitter connects with a Type K thermocouple, other types of thermocouples can be specified by the customer on request, making the sensor fully flexible for integration. All in the reliable NEON form factor that comes as a battery-powered I-IoT device, communicating wirelessly via LoRaWAN, with the option for an IECEx / ATEX Zone 0 certification, if required or wanted.
IECEx / ATEX Zone 0 certified variant
Designed for industry from the very beginning, IMI’s NEON product line is built to not only operate in industrial sites where explosive gasses are being handled but also all other elements that a sensor may be exposed to in the course of its >10 year lifetime (varies by environment and system). It has been tested and certified to work in conditions from -40° to 80° Celsius without hampering performance. The devices are designed and engineered so that they can be safely and securely deployed in a wireless network and are fully remotely configurable, ensuring not only longevity but also reliability within an operation.
Additionally, IMI delivers spare parts and product lifecycle support. It has an extremely long battery lifetime which is why, the sensor can continue to be used with the correct refurbishment kit. This way, periodical maintenance can be kept at a minimum.
The NEON Temperature Transmitter can be installed / mounted using various methods. The thermocouple or RTD desired, can be specified by the customer. The sensor is flexible and adapts to the various types.
NEON product line – LoRa devices designed for heavy industry
The 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 has no vendor lock-in, 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 can be extended dramatically. This international networking technology is quickly becoming the industry standard.
NEON stands for a standardised approach to collecting data points from within the operation and a general approach to creating integrated solutions with existing IT ecosystems.
