4. Main features
• Robust transmitter for angular position suitable for fi eld
applications
• Highest degree of mechanical and electrical safety
• Proven capacitive scanning system
• No wear, low annual maintenance and mountable any-
where
• Vibration- and shock-resistant
• Measuring range, sense of rotation, zero position and
linear/V characteristic can be adjusted by a switch and
two push-buttons
• Analog output signal 4...20 mA, 2-wire connection
• Zero position and end position are independently adju-
stable
• Capacitive scanning system provides absolute position
immediately after activation
• With explosion prevention „Ex ia IIC T4 Gb",
„Ex ia IIIC T80°C Db" and
„Ex tb IIIC T80°C Db" according to ATEX and IECEx
available
• With GL (Germanischer Lloyd) available
