Temperature monitoring system SENTINEL

for grain

SENTINEL is an electronic control unit used to check stored cereals temperature in silos or warehouses. These cereals warn up thanks to the fermantation, so the control of the temperature is an important function to see the first symptoms of the fermantation, in this way, you can also prevent useless and expensive recycles or the deterioration of the product that caused a loss of profit. Sentinel has been constructed based on the digital technology of the bus seriale RS 485 with 4 electric wires, so you can eliminate installation expenses for the patch of hundreds of leads (as the traditional system), and spread the installation to link the principal line ( 4 leads ) with new “remote“ cards. Sentinel important characteristics are: the principal communication line made up a cable with 4 electric wires (to a maximum distance of 2 km), where you can connect 256 “ REMOTE “ cards, all of them have 32 temperature sensores with a maximun installation capacity of 8.192 points of measure. ADVANTAGES: Sentinel, the electronic control unit used to check automatically the temperature, is made up the following units: Graphic display back lit up. Integrated printer with common paper and planned breaks timer. Possibility to decide different warning temperature for every silos. The choice of temperature scanning between aut-man. Relè coming for warning systems connection that can be compatible with every kind of meter, 12 v feed. “REMOTE” cards: electronic cards for the comunication that are assembled on silos or in warehouses. These cards manage a maximun of 32 digital temperature sensores LM 335.
