Putting Presence Detectors through their Paces
A real-life measurable basis for comparing the way presence detectors actually work not only ensures a high standard of quality and performance. This shows who's the No. 1 in the technology stakes.
Performance by comparison
To be in a position to compare all presence detectors, they must be measured under exactly the same conditions: Position, room temperature – excluding other non-controllable infl uences – and, in particular, the same, standardised movement at all times. Only then is it possible to compare the true performance of presence detectors. At STEINEL Professional, we have a special test room that meets all of these conditions. This means we know our own sensors and those of all our competitors inside out.
The optical system, its resolution density, reach, detection characteristics and evaluation software are all crucial to the quality of a presence detector. Standardised testing provides us with the tremendous precision and the knowledge with which we bring objectivity and hard fact into the equation: It's an incorruptible measurement process that permits international comparison.
We know what we're talking about
Standardised movement is performed by a robot that simulates the human forearm: our NEMA arm robot. Using a temperature-controlled, standardised forearm model of unchanging mass, it performs a 90°-movement that's always the same (conforming to the American NEMA Standard).
Whether and the speed with which the sensor detects it is recorded in a measurement protocol that ultimately provides the basis for producing the detection diagram. There's not a sensor in the world that can't be measured and compared as objectively as this. On the basis of this process, we know exactly how every motion and presence detector performs. And we are extremely proud of where our products rank in this comparison – but at the moment we'll politely refrain from comment.
