Series 40 (NAMUR)
Potentiometer (B)
Series 40 analogue
For adjustable sensors the potentiometer is placed under
a sealing screw (A). For some plug-in sensors and sensors
with special housing (B) the potentiometer is placed on
the side without a cover.
Adjustment:
• Turn clockwise to increase sensitivity
• Turn anti-clockwise to decrease sensitivity
KAS non-flush mountable for level control:
• Immerse the active area (= thread-free zone or 25 mm)
into the medium.
• Turn the potentiometer clockwise until the sensor
switches.
• Then turn the potentiometer a further 90° to the right
(= reliable switching).
• If the sensor switches immediately when immersing
the sensor then turn the potentiometer to the left to the
switching point and then to the right again as described
above.
