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. The temperature monitoring system is capable of measuring temperature changes inside the silos to enhance real time temperature monitoring.

Frequently Asked Questions
Q1: Why is temperature monitoring essential for grain storage silos?
A1: Temperature is a vital indicator of grain quality. Temperature increases inside silos often signal potential issues, such as grain rotting or pest infestation. Early monitoring helps prevent spoilage and loss of value.
Q2: What is the measuring range and accuracy of the sensors?
A2: The system measures temperature from -30ºC to +70 ºC with an error margin of ±1ºC. It measures humidity from 20% to 99% RH with an error margin of ±5% RH.
Q3: What communication technologies are used in this monitoring system?
A3: The host and extension units utilize 485 long-distance communication technologies, while the extension and internal silo sensors use advanced digital one-wire bus technology.
Q4: What kind of sensor is used inside the cables?
A4: The system uses imported USA DALLAS 18B20 digital temperature sensors, which are highly sensitive and ensure stable signal transmission.
Q5: How does the system handle potential false alarms?
A5: The system features a special initial point setting for silo alarms, designed to prevent false alarms caused by sudden natural variations in external temperatures.
Q6: What options are available for data transmission and analysis?
A6: The system supports both cable and wireless data transmission. It also includes comprehensive analysis tools to display temperature curves, scatter-plot charts, and column type charts.
