Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to a sensor used for monitoring vibration and temperature of mechanical equipment. Background Art

[0002] Modern industrial production utilizes a large number of mechanical equipment. After long-term use, these equipment can experience various faults, impacting normal operation and even causing personal injury. To ensure the continued safe and reliable operation of these equipment, continuous monitoring of their operating status is necessary. One effective approach is to continuously collect vibration and temperature data from mechanical equipment during operation. This data can be used to analyze operational trends and perform predictive maintenance, thereby reducing unplanned downtime and repair costs.

[0003] Currently, many sensors on the market for collecting vibration and temperature data from mechanical equipment have several drawbacks. For example, some sensors can only collect vibration signals alone, requiring additional equipment to collect temperature signals. Some sensors use traditional data transmission methods such as RS485, which prevents flexible deployment. While some sensors use wireless data transmission, the wireless signals are weak and easily affected by environmental interference and cannot overcome building obstructions, resulting in poor data transmission signals and high packet loss rates. Therefore, it is necessary to propose a sensor for mechanical equipment vibration and temperature monitoring to address these issues. Utility Model Content
