ETCH01 Tachometer Module – Although
the EVA system accurately calculates elevator velocity and distance in elevator systems without the need of a tachometer, there are times
when speed must be measured precisely in constantly moving systems such as escalators. To
meet these needs, the ETCH01 tachometer is an extension to all EVA-625 systems. This
provides the ability to measure & record, or display in real time, direct drive speed
measurements for escalator handrails & steps, escalator stops,
elevator doors, or any moving system.
