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.
