SAS Series Wireless Bolt Preload Sensors
The SAS series wireless bolt preload sensors are industrial-grade sensors designed specifically for monitoring the health status of critical bolts in industrial equipment. The sensors feature resistance to interference, high accuracy, ultra-low power consumption, and durability, making them suitable for long-term operation in harsh industrial environments.
Each sensor uses ultrasonic technology to accurately measure the time of the reflective ultrasonic waves. Additionally, the sensor is equipped with a temperature probe to measure the surface temperature of the bolt. By applying a temperature compensation algorithm, the sensor can measure accurately and reliably the bolt's preload (axial stress) at different temperatures.
SAS100/SAS100A come in a single integrated enclosure, ensuring easy and convenient installation. SAS100 is suitable for monitoring regular bolts, while SAS100A is specifically designed for monitoring anchor bolts. Moreover, SAS120 adopts a slim probe design, making it suitable for situations where the bolt's surface has limited height or internal hexagonal holes, such as blade bolts in wind turbines.
The sensor data is transmitted through a wireless sensor network to a remote monitoring platform. Users can remotely monitor the bolt preload and receive timely alerts in case of loosening, fatigue, or fracture of the bolt. This allows continuous tracking of the entire process of bolt loosening, ensuring safe equipment operation, preventing unplanned downtime, and reducing maintenance time and costs.
