RSF Elektronik: Angle Measurement (MSR 40 MER Series)
Modular angle measurement devices with or without integral bearings establish the connection between the mechanism and the control electronics. In the field of automation, they are used both for recording the angle and position and for determining speed and acceleration values.
Modular angle measurement devices are required to convert the recorded value of a mechanical variable into electrical signals so that they can be evaluated by output devices, PLCs and industrial PCs.
MSR 40 MER Overview
Modular angle measurement devices MSR 40 MER without integral bearing are used as position and rotator control for electrical drives and in the measurement technology.
