Position transmitter "Ripos"

Absolute Angle transmitter "Rivert"


RIPOS-Intelligent position measurement
Absolute Encoder

The rugged weather-proof MGI encoder is designed for absolute measuring of mechanical positions ( angular displacement, lift, distance, travel). The displacement to be measured is conveyed by gear wheel, chain, lever, universal joint-shaft, etc. to the input shaft of the transmitter. The compact and robust design as well as the simple assembly enable a wide range of applications.
Signal processing within the unit is continuously digital by a micro-controller. The transmitter may be set on-site by an operating unit with display or remote via HART / LON fieldbus connection. Position lineriasation is available by programming an integrated look-up table. Perfect function of the transmitter is surveyed by cyclic self tests.
