steel grain silos temperature monitoring 18b20 cables for sale
Product Description:
Temperature Monitoring System is the key component of grain storage control system, it is very important to keep the stored grains at the right temperature and prevent spoilage, loss of value. Temperature is the important factor to affect the grain quality. The temperature changes of stored products will indicate that there are problems inside the grain storage silos. Whenever grain rots or when there is a pest problem, the temperature in the silos will rise to indicate there is a problem. Shelley Brand temperature monitoring system is capable of measuring temperature changes inside the silos to enhance real time temperature monitoring.

Function introduction:
1),Host and extension are using 485 long distance communications technologies.
2),Extension and sensor inside of silo will adopt advanced digital one-wire bus technology
3),Imported digital temperature sensor.
4),Intelligent system fault self-checking.
5),Programming interface is simple.
6),Have the data analysis tool of Temperature curve, Temperature scatter-plot chart, column type chart etc.
7),Temperature and humidity limit alarm. Daytime temperature limit alarm. temperature rise temperature rise
8),The special initial point for silo alarm can prevent the false alarm which is caused by the great variation of temperature.
9),Simultaneously detect temperature & humidity of grain.
10),Support circular measurement, at any time refresh measure temperature& humidity.
11),Support continuous level indicator, ventilation control function.
12),Support cable/wireless data transmission.
Device introduction:
Temperature testing Cable: The temperature line has three or two cores inside, usage: convey signal and power.
Sensor:
the sensor is exported from USA DALLAS 18B20, as a key component, it is high quality and sensitive.
Extension:
the extension can insert 8-16 testing lines, generally speaking, we install one extension on per silo roof,
Its function is receiving and gathering the signal, then conveys the signal to display terminal.
Because the long distance between extension and display terminal, we have two connect ways: wireless and wire.
The wireless technical is mature and it need not power, because it can produce power by itself, it use solar power.
At the same time, even though the extension is on the roof, it still can avoid the lightning, after lightning, it will refresh to work.
