Overview

The SA series wireless bolt loosening sensors are industrial-grade sensors designed to monitor the fastening status of critical bolts in industrial equipment. Built for harsh environments, these sensors offer exceptional resistance to interference, high accuracy, ultra-low power consumption, and long lasting durability for continuous operation.
Utilizing MEMS technology, each sensor accurately measures the relative rotation angle between the nut and bolt, effectively tracking bolt loosening. Additionally, the integrated attitude sensor detects movement and potential drops, providing enhanced monitoring capabilities.

The SA210 model is ideal for standard bolt applications.

The sensor is transmitted wirelessly to a remote monitoring system, enabling users to monitor loosening angles, receive timely alerts, and track the entire loosening process. This ensures safe equipment operation, minimizes unplanned downtime, and reduces maintenance costs.

The SA series bolt loosening sensor is installed non-intrusively on the nut. Using advanced signal processing technology and algorithms, it rapidly and precisely measures the nut's loosening rotation angle relative to the bolt, providing an accurate assessment of the bolt's fastening status.
