Overview

The SA-S series 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 SA220S features an ultra-thin design, perfect for installations in confined spaces such as blade bolts in wind turbines.

Each sensor is equipped with an RS485 interface, capable of transmitting the data through the Modbus protocol. Users can remotely monitor the loosening rotation angle and receive timely alerts in case of bolt loosening, continuously track the entire process of bolt loosening, ensure the safe operation of equipment, prevent unplanned downtime, and reduce maintenance time and costs.

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