DMV-100 Rotor Creep and Speed Detector - Installation Manual

1.

OVERVIEW OF THE DMV-100 ROTOR CREEP 
AND SPEED DETECTION SYSTEM

Figure 1 : DMV-100 Rotor Creep and Speed Detection complete measuring chain

The DMV-100 System is a complete measuring chain for detection of rotor motion (creep) and monitoring of 
machine rotational speed (RPM). 

The DMV-100 System is comprised of:
