Dryer Master DM510 Installation Manual
Inlet Moisture Sensor Installation
Sensor Location
The Inlet Sensor should be placed vertically at the inlet to the grain dryer (in or near the garner bin).
See Figure 7 - Alternate location for inlet sensor on column dryer and Figure 8 - Round dryer
installation location for details.
There are two conditions that must be met for the Inlet Sensor to operate correctly.
1. The Inlet Sensor must be completely covered by compacted grain at all times.
2. The Inlet Sensor must also receive a good (representative) sample of the grain.
These two conditions are usually met if the
Inlet Sensor is located near the centre of the
longest vertical side of the garner bin.
However DO NOT locate the Inlet Sensor
directly under the inlet spout.
Grain that is
erratically compacted will dynamically change
the relative readings of the inlet sensor
contributing to false readings. Inaccurate or
false readings of the inlet sensor will
adversely affect control of the dryer.
Installation should minimize the probability of
steam reaching the sensor. Install the Inlet
Sensor at a level higher above the hot zone
than the width of the hot zone. For example if
the hot zone is a foot wide leave at least a foot
between the hot zone and the sensor. If this is
not done, the static pressure in the hot zone
can force moisture-laden air past the sensor.
Due to the cold state of the sensor, moisture
will condense from the air onto the sensor
resulting in false readings. Inaccurate or false
readings of the inlet sensor will adversely
affect control of the dryer.
If the sensor is placed in a location such that it
will get an excess of fines or trash this will
contribute to errors or false readings.
Inaccurate or false readings of the inlet sensor
will adversely affect control of the dryer.
Install the Inlet Sensor in a place where water
cannot run down the surface of the sensor. In
the dryers which have an open top allowing rain to penetrate the grain (or excessive cold) will cause
condensation to form on a fin sensor. The sensor needs to be moved to the surge hopper or other
more appropriate location.
