DATANIT Probe Thanks to our atmosphere control Reduce your gas consumption up to 50% For all nitriding and nitrocarburizing treatments For all types of furnaces including low pressure Automatic calibration Reproducibility and traceability of your production A unique, patented and proven system to meet the most rigorous aeronautical standards. (AMS. Nadcap, PR) The Datanit probe has been designed to accurately and continuously measure the following: • • kN characteristic of nitriding atmospheres kN and kC characteristic of nitrocarburizing atmospheres It also measures kO when oxygen is present, as well as post oxidation. It works on all types of furnace, including low pressure, and requires no maintenance. Reproducibility of measurements is ensured by automatic calibration. The Datanit probe can be used as a measurement system as well as for monitoring by tracing and alarming when the gas composition is dangerous for the load or the installation. In combination with a PLC, it can also be used to regulate characteristic values for reproducible and reliable metallurgical results.

Measurement principle : The Datanit probe consists of several measuring cells that complement each other to measure the composition of the gaseous atmosphere (see figure below). The gas is drawn into the probe by injecting a small amount of nitrogen at high speed (Venturi effect). A lambda probe determines its oxygen partial pressure. Then, it passes through a hydrogen sensor, then a cracker and finally a second hydrogen sensor. The difference in hydrogen partial pressure between the two sensors is used to calculate the partial pressure of ammonia. The partial pressures of the other gases...
