N.E.T. Technology

MICROPROCESSOR

When N.E.T. started to design their new Infrared sensor technology they wanted their sensors to be able to extend beyond the basic routine operations such as powering the IR source and acquiring signals from the detectors. This is the traditional approach by sensor manufacturers.

N.E.T. wanted their sensors to really think by themselves and to simplify the integration by the end customers.

N.E.T. wanted the sensors to be truly SMART.

ARM® Cortex®-M4

Today, all our Infrared sensors are based on an ARM® Cortex®-M4 core platform providing all the speed, versatility and computing power we need to bring you the highest performing gas sensors available in an Industry Standard 4 or 7 series sensor foot print.

Although the Microprocessor provides our sensors with exceptional reliability, speed, and versatility it also delivers industry-leading Low Power consumption. This enables N.E.T. to offer a genuinely low power option for our 20mm series. Typically, sensors of this size (20mm diameter) lack integrated electronics, meaning signal processing must be carried out on a separate external board.

For the user, the advantages of having a microprocessor-based sensor are many:

• The sensor has a high-level interface, with a standardized, linear output. This eliminates the time and complexity required to deal with low-level signals and calculations.
• Communication with the sensor is bidirectional via digital protocols (Modbus and UART). The user can not only get readings, warnings and alarms but also change communication parameters and input updated calibration values.
• Fail-safe operation and dependability are enhanced by several self-checks routines and consistency controls continuously performed by the sensor. This allowed N.E.T. IR line to reach SIL2 Safety Integrity Level (read more about SIL).
• Faster response time, with our accelerator algorithm (T90<30s).
• Superior performances at high volumes of concentration, with the N.E.T.
