2. Scope of delivery

1 Postion Feedback Transmitter KINAX SR709
1 Operating instructions in German and English
1 Type examination certifi cate, only with ATEX-approval
3. Application
The position feedback transmitter consists of a KINAX angle
transmitter and a reduction gear which converts a linear mo-
vement into an angle of rotation of 0 ... 90°. Both parts are
contained in a robust cast aluminium housing. The mounting
part to the control valve is based on NAMUR recommendations,
(standards working group for measuring and process control in
the chemical industry).
The pick-up of the stroke movement is made by means of a slotted
lever. The adaption to strokes between 10 and 140 mm is made
with an external lever transmission and by an internal gear ratio.
The external lever transmission can be adjusted in such a way, that
the internal cam shaft makes an angle of rotation of approx. 90° for
a full stroke. The measuring range of the built-in angle transmitter
KINAX 3W2 then corresponds with this angular rotation of 90°.

4. Main features
• Movement- and stroke measurement with range limits 0...10 to
0...40mm
• Setting of the measuring range is achieved via adjusting the lever
system pivot point. More precise calibration is via zero and span
potentiometers / Optimum adjustment of zero and span can be
made to meet individual requirements
• Measuring output: DC current signal (load-independent, 2, 3 or
4-wire connection)
• Capacitive scanning system / Non-wearing
• Unit in fi eld type housing in cast aluminium with NAMUR mounting
part for fi tting to control valve
• With explosion prevention „Ex ia IIC T6 Gb", according to ATEX
and IECEx available
