EN – TECHNICAL USER GUIDE

PRODUCT DESCRIPTION:

MS 44R is a capacitive relay sensor for
detection of feed, grain and solids. The sensors
have relay output including switch function.
Fields of application:
• Level control in silos and containers
• Controlling the filling and emptying process.
MOUNTING GUIDE (FIG. 1):
MS 44R includes M30 thread. Mount it in a
ø30 mm hole and tighten using the locknuts
included.
DOL 44R is made in a ø30 mm smooth design
mounted in a PG36/M40 gland.

INSTALLATION GUIDE (FIG. 2):
Supply voltage is connected to the blue and
brown wire.
The load is connected in series with the relay
contact of the sensor.
STOP by activating the sensor: Use the black
wires 1 and 3.
START by activating the sensor: Use the
black wires 1 and 4.
NOTE! The internal relay is in position NC
when the supply voltage is connected and the
sensor is activated - wire 1 and 4 are
connected.

DOL44RH has a built-in, controlled heat
function which prevents frost and
condensation on the sensor. This assures
optimum detection in very cold and damp
environments.
The heat function is only possible for the
90-265 V AC voltage version.
