What performance is it capable of?
The Magnos28 offers improved drift stability, helping to realize very low measuring ranges of from 0 to 0.5 vol%. With improved sensitivity at very low oxygen concentrations, it offers drastically reduced moisture influence, while its response to other dia- and paramagnetic gases matches theoretical values, reducing measurement uncertainty.
An ingenious system of internal gas flow management directs the process gas instantly to the highly responsive microwing, giving up to a 15 percent improvement in response time. Its internal chamber volume is reduced by factor of three. Combined with completely redesigned gas paths and optimized drillings, this results in rapid gas exchange.
For extra speed there is also a special version offering a rise time of less than 1.3 seconds, making it one of the fastest magneto-mechanical oxygen sensors available. A minimum required gas flow of only 0.15 l/min makes the Magnos28 the perfect choice for processes with rapidly changing oxygen concentrations.
Minimizing external influences delivers unprecedented resolution. A wide dynamic range and high suppressed ranges are achieved by an immediate 32 bit A/D conversion next to the physical sensor, minimizing signal noise. This improves performance across complete 0.5 to 100 vol% O2 range.
Reduced temperature and pressure effects are achieved by a gas flow bypass system thermally decoupled from the sensor block. This ensures defined internal flow and minimizes influences on the detector temperature balance. Intelligently arranged sensors also detect and compensate for external influences.
