Product Overview

The Nitrogen Dioxide Gas Sensor Device, in combination with the principle of coulometry, delivers a high-precision gas detection technology. The higher the Nitrogen Dioxide concentration the faster the sensor will be drained. Therefore the sensor lifetime will deteriorate rapidly and more maintenance will be needed.

ECtox’s big advantage, while continuously working with a high Nitrogen Dioxide concentration, is its long lifetime. A pump easily transports the gas to the sensor without the need to calibrate. The sensor can be used for emission measurement, Nitrogen Dioxide leakage detection and process control. The output signal, RS485 (Modbus), will effortlessly connect with a gas device, DCS, PLC or wireless systems.

Principle

The ECtox device contains an EC Sense solid electrolyte Nitrogen Dioxide gas sensor featuring long lifetime, robustness and selectivity. Based on a specific electrochemical reaction and in combination with a sample pump the device measures Nitrogen Dioxide concentration in a wide range. The gas reaches the working electrode of the sensor by a certain pump volume, which is always constant. All gas in the offered gas volume will be consumed by the sensor. It creats a signal peak, which is proportional to the Hydrogen concentration in the measuring gas. No calibration is necessary due to the coulometric measuring principe.

The sampling system is good for different densities, the speed of diffusion and convection is usually vslow or depends on the environment, and temperature and different concentration influenced the speed of molecular motion. Sampling System let gas easy going to sensor.
