Temperature Measurement System Setup

In grain storage management, a scientifically and reasonably set - up temperature measurement system is the core link to ensure grain quality and storage safety. Through precise temperature monitoring, grain silo managers can promptly grasp grain temperature changes and prevent issues such as spontaneous combustion of grain piles and pest infestation.

Core Principles of Temperature Measurement System Setup

Accurate Coverage

The setup of the temperature measurement system should ensure comprehensive and accurate coverage of grain temperature in the silo. By reasonably arranging temperature sensors and cables, monitoring blind spots are eliminated, and real - time control of temperatures in all parts of the grain pile is achieved.

Adaptation to Storage

Different silos vary in size, shape, and type of grain stored. The setup of the temperature measurement system needs to be adapted to local conditions. According to the specific situation of the silo, flexibly adjust the number, length of temperature - measuring cables, and the distribution density of sensors to meet diverse storage needs.

Matching Silo Diameter with Cable Quantity

The number of temperature - measuring cables should be scientifically configured based on the diameter of the silo. Generally, a silo with a diameter of 12 meters is equipped with 5 temperature - measuring cables, 18 meters with 7, 24 meters with 9, 30 meters with 12, and 36 meters with 16. This configuration follows the empirical formula N = Ø/3 rounded down, ensuring even cable distribution in the silo and effective grain pile temperature monitoring. For example, in a silo with a diameter of 24 meters, 9 temperature - measuring cables can cover the entire grain pile, achieving comprehensive temperature monitoring.

Determining Sensor Quantity Based on Vertical Depth

Grain pile height is a crucial factor in determining the number of sensors. Usually, for every 2 - meter increase in grain pile height, one more sensor is added. If the grain - filled height of the silo is 30 meters, then 15 sensors need to be arranged on a single temperature - measuring cable.

Handling Edge Blind Spots

In the edge area of the silo, due to the shape of the grain pile and the influence of the silo wall, it is easy to form temperature monitoring blind spots, also known as the "cold bridge" phenomenon. To solve this problem, a short cable with a length of 3 meters can be added in the area 0.5 - 1 meter away from the silo wall outside the last temperature - measuring cable. This short cable can effectively cover the edge area, ensuring that the temperature measurement system has no blind spots in monitoring the grain pile temperature.
