The Cambridge Sensotec Rapidox zirconia oxygen gas analyser is designed to measure ppm levels of oxygen which make them ideal for nitrogen gas based applications.
Measurement of residual oxygen levels is critical in order to maintain a consistent nitrogen atmosphere, Cambridge Sensotec says.
The presence of oxygen can increase the chances of oxidisation resulting in a compromise in quality in parts produced. By using the Rapidox gas analyser in the process, users can save on costly part rejects or failures, the company claims.
The Rapidox range of gas analysers are designed to offer fast, accurate and reliable oxygen measurements ensuring quality and efficiency.
Each Rapidox analyser is supplied with powerful software allowing users to data log oxygen measurements to aid quality control and traceability.
The software also allows for the control of external devices, for example a proportional flow control valve to optimise the use of nitrogen, which leads to significant cost savings by reducing nitrogen usage.
A selection of metal based nitrogen applications include:
Annealing is the process used to soften metals by heating the metal and maintaining a set temperature, followed by controlled cooling.
Sintering is an industrial process using compressed metal or ceramic powders to form objects.
Brazing is a process of bonding two or sections of metal together by melting a softer metal with a lower melting point across the joins.
The hardening and tempering process of heating and rapid cooling metal increases its strength and durability. Quality and consistency are improved by using nitrogen within a controlled atmosphere during the process.
