Maintenance of Temperature Measurement System

In grain storage management, the normal operation of the temperature measurement system is crucial for monitoring grain pile temperature and preventing spontaneous combustion and pests. To ensure the system is always in its best working condition, scientific and reasonable maintenance is essential.

Core Strategies for Maintenance

Prevention - Oriented

Maintenance of the temperature measurement system should follow the principle of prevention - first. Regular inspections and maintenance can identify and resolve potential issues in a timely manner. This prevents system failures that may cause interruptions or inaccuracies in monitoring data. Develop a detailed maintenance plan to ensure all maintenance tasks are completed on time and to a high standard.

Professional Personnel and Standardized Operations

Maintenance should be carried out by technicians who have undergone professional training. They are familiar with the structure and working principles of the temperature measurement system. They can accurately diagnose and repair faults. At the same time, strictly follow operating procedures during maintenance to ensure the process is safe and efficient.

Key Links in Maintenance

Annual Calibration

Temperature sensors are the core components of the temperature measurement system. Their accuracy directly affects the reliability of the monitoring data. Over time and with environmental changes, the performance of sensors may drift. Therefore, annual calibration is necessary to ensure their measurement accuracy.

Calibration Method

Use an ice - water bath (0℃) and a constant - temperature water bath (30℃) as calibration reference points. Place the sensors in them and check and adjust their output values. If the error exceeds ±0.5℃, the sensor needs to be replaced.

Daily Patrol Inspection

Inspection Content

Daily patrol inspection is the basic work of temperature measurement system maintenance. It mainly includes the following aspects:

Check if the heavy hammer is buried in grain: The heavy hammer is used to keep the temperature - measuring cable vertical.

Inspect the cable sheath for wear: Worn cable sheaths may cause short - circuits or signal transmission interruptions, endangering the normal operation of the system.

Observe the status of the sub - machine indicator lights: Abnormal lights or no display indicate possible faults.

Inspection Frequency and Record - Keeping

Based on the scale of the grain silo and management requirements, establish a reasonable inspection frequency. It is generally recommended to conduct at least one comprehensive inspection per week. At the same time, record the results of each inspection, including problems found and measures taken. This helps track maintenance effectiveness and accumulate management experience.
