About                 Grain Management

An estimated one-third of all harvested grain goes to waste. This is predominantly due to difficulties during storage.

After the harvest, the grain continues to be in the ripening process. Moisture and thermal energy is released.
This encourages the growth of mold fungus and insects.

Our Grain Management System enables you to have total automated control of your storage.
This is essential to  introduce  preventive  procedures.

Our program informs you via computer, tablet or smartphone with alarms and controls at the right time to protect your grain.
From  grain  temperature  and humidity information to inventory management, we’ve got you covered.

Make  grain  storage  more efficient and keep the quality of the grain!

Improve reliability of the silo plant operation by our intelligent prediction and protection technologies.

The servicing costs can be highly reduced  by increasing the safety and keeping the quality of grain by the predictive intelligence of the components exactly suited to the application field.

Temperature Cables
Temperature cables consist of temperature sensors (sensor cable) and protection tubes.

The digital temperature sensors are mounted on a two wire cable which is inserted in an internal protection tube. This makes the sensor cable easily retractable.

These fully isolated sensor cables are protected by a robust outer protection tube.

The protection tube will be built to various lengths to match
the height of the silo and mounted in the silo. They may be installed on the roof or under the roof.

The high-accuracy digital sensors along the cables are individually checked for their temperature measurements. The spacing between sensors  may be a standard distance  or customized to match the installation.
Temperature and Moisture Cable
The cable contains sensors which measure relative hu-
midity  and  temperature  of  the  grain  at  the  specified
points of the silo.

The temperature and humidity sensors can also be lo-
cated outdoors or at the fans and vents within the grain
silo to measure ambient conditions.

The sensor cable installed with temperature and humid-
ity sensors communicates on a serial network with two
wires.  This  simplifies  the  installation  of  the  humidity
sensors and the combination with the temperature sen-
sors in the storage bins.

•  Industry-leading  long-term  stability  (1.2%  RH  over  five
years):  Minimizes  drift  over  time,  helping  to  maximize
grain drying performance

•  Combined humidity and temperature sensor in one pack-
age  allows  the  grain  manager  to  collect  data  from  one

•  Optimization of humidity and temperature range

•  Accuracy: ±1.7% RH accuracy (humidity performance) and
±0.3°C accuracy (temperature performance)

•  Hydrophobic filter: Protects the sensor against contami-
nation due to dust or excessive moisture.

The temperature and humidity cables are used to measure the moisture and temperature inside the grain silos in order  to  help  grains  remain  dry  and healthy.

The temperature and humidity cables that  are  suspended  from  the  top  of the  silo  are distributed  within  the grain bulk.
Remote Terminal Unit

The  ERG  T9  is  a  strong  remote  terminal
unit (RTU) operating as an interface con-
verter to digital sensors and other analog
or digital  signals. It can be connected  to
standard LAN systems via modbusRTU and
TCP/IP Ethernet.

I2C, SPI, rs232, rs485, USB, ethernet and
wireless interfaces make it a unique equip-
ment ideal as a signal converter between
site sensors and PC SCADA systems.

RTU is designed for  use  with  various  industrial  digital  or analog temperature and humidity sensors.

Supervise  your  grain  storage  at  any time from anywhere!
Grain Management Software shows you the situation inside of your silo at any time and will  inform  you  with  the  grain  temperatures.

The  software  runs  on  tablet,  smartphone or on your computer!

The  temperature  and  humidity  data  are read, processed, saved and displayed. The specified data will be transferred to other control devices to enable a cool and safe grain storage. 

Software functions:

•  Reading the temperature data from the RTUs

•  Visualizing current temperatures

•  Data  analysis  for  each  sensor: Minimum/maximum/trend/average  for time intervals, day, week, etc.

•  Alarms for each sensor (multiple types of alarms; on the plain value or a breach of a trend in a certain time interval)
