The Isolcell N2 ORS® Oxygen Sensor

ISOLCELL has developed a highly reliable measurement instrument.

The Isolcell N2 ORS® Oxygen Sensor is equipped with three individual sensors, supported by reciprocal measurement diagnostics with a triplicated architecture with majority redundancy.

This means that the values measured are processed using a 2oo3 (two-out-of-three) voting design, thus providing a precise and unequivocal value and a high level of safety, as can be seen from the fact that even our oxygen sensors are IEC 61508:2010-certified with the significant reliability level of SIL-3.

The unit that manages the entire system

The N2 ORS® control indicating equipment is the unit that manages the entire system. The panel manages sampling from the virtual grid, ordering the activation and/or deactivation of the integrated and interfaced equipment making up the system, according to scheduled intervention plans.

It also manages all control systems to avoid the undesired formation of under-oxygenated atmospheres (compared to atmospheric values) in environments adjacent to the areas to be protected, along with shut-off procedures when the pre-set oxygen concentration thresholds are reached, and activation of alarms when needed.
