Technical Parameters of Grain Silo Temperature Measurement System

In modern grain storage management, a high - performance grain silo temperature measurement system is a key device to ensure grain quality and storage safety.

Measurement Range

Adapt to Different Silo Environments

The measurement range of a quality grain silo temperature measurement system should be at least between - 30℃ and 60℃. This ensures precise monitoring of grain pile temperature even in extreme climate conditions.

Match Grain Variety Requirements

Different grain varieties have varying storage temperature requirements. For example, wheat is suitable for long - term storage at lower temperatures (10 - 15℃), while rice can be stored at slightly higher temperatures (15 - 20℃). By properly setting the measurement range of the temperature measurement system, it can better meet the storage needs of different grain varieties and provide reliable protection for safe grain storage.

Temperature Measurement Accuracy and Resolution

The Decisive Role of Measurement Accuracy

A high - accuracy temperature measurement system can more truly reflect changes in grain pile temperature and detect potential risks in a timely manner. Generally, the accuracy of a grain silo temperature measurement system should reach within ±0.5℃. In some special grain storage scenarios with extremely high temperature control requirements, such as seed grain storage, a higher - accuracy temperature measurement system may be needed to meet the needs of fine - tuning.

Resolution's Ability to Capture Subtle Changes

A high - resolution system can capture subtle fluctuations in grain pile temperature, providing more detailed data support for managers. For example, when the grain pile temperature rises by 0.1℃, a high - resolution temperature measurement system can detect and record this change in a timely manner. This helps managers take measures in advance to prevent abnormal temperature spread.

Sensor Performance

Thermistor Sensors

Thermistor sensors measure temperature based on the characteristic that metal resistance changes with temperature. They have advantages such as high accuracy and good stability. Their measurement accuracy can reach ±0.1℃, with a resolution as high as 0.01℃. They are suitable for grain silo temperature measurement scenes with high temperature accuracy requirements in medium - and low - temperature environments.

Thermocouple Sensors

Thermocouple sensors use the Seebeck effect for temperature measurement. They have advantages such as simple structure, fast response speed, and wide measurement range. They can adapt to various complex temperature environments in grain silos, such as high - temperature drying silos and other special scenes.
