5. Installation
For correct operation and measurement complete filling of senso
r’s measuring
channel with grain must be ensured.
Depending on the design of grain dryer sensors can be installed different ways.
Several methods are described in this manual.
To control flow moisture content of at the inlet the sensor should be installed on
the side wall of bunker in its upper part where the bunker is filled. A315 sensor
should be placed between high and low level sensors of the drying column closer to
the low level sensor (fig. 29).
fig 29. Installation on the side wall of the bunker
As the grain is filling the drying column and sensor measurement channel is fill-
ing as well and the sensor begins to measure moisture content of the product. When
the grain level falls below the sensor level, the measurement channel becomes emp-
ty of grain and moisture sensor reads zero values and automatic calibration is per-
formed (green light
on the panel
)
. The process repeats for the new loading of
grain.
To control flow moisture content at the outlet of dryer the sensor is placed in
output bunker above output conveyor (fig. 30).
When a certain portion of dried grain is discharged from the bunker, moisture
contents sensor gets fully covered and grain slowly passes through the measurement
channel and is then carried away by output conveyor. Measurement continues until
the measurement channel is empty. After this the sensor is automatically calibrated
