Product description

Electromagnetic ultrasonic double wave bolt stress meter

(Model: ST100)

Electromagnetic ultrasonic double-wave bolt stress meter ST100 adopts electromagnetic ultrasonic double-wave in-situ axial force detection technology, which can measure high-strength bolts in service without knowing the original state of each bolt. When measuring, there is no need to apply couplant on the bolts, and no need to polish the surface. You can directly measure bolts with raised text on the bolt head, small diameter studs, bolts with hexagon sockets, and bolts with concave surfaces. It is widely used in the acceptance of pre-tightening force of bolts of large-scale equipment under construction, handling of bolt failure problems of large-scale equipment in service, auxiliary verification of bolt construction technology, and bolt axial force inspection of large-scale equipment in service.

<<< product description◎ The world's first electromagnetic ultrasonic vertical and horizontal wave double-wave tension testing equipment (patent number ZL201810893704.4);
◎ Without disassembly in situ, there is no need to grind the surface of the workpiece, realizing rapid detection of high-strength bolt axial force;
◎ Portable design, lithium battery power supply, battery can be replaced; 5-inch high-brightness display, convenient keys, and realize one-handed operation;
◎ The equipment is optimized for on-site design, realizing automatic wave selection, automatic output and one-key storage, etc. The measurement time of a single bolt is less than 10 seconds;
◎ Integrated design helps field testers get rid of traditional heavy equipment boxes and mobile computers, easily enter and exit small places such as wind turbine hubs, and quickly complete test tasks;
◎ The stored data can be imported into the computer, and can communicate with the mobile terminal of the mobile phone via Bluetooth, upload the data to our bolt cloud or download the relevant configuration and data from our bolt cloud;
◎ Powerful bolt cloud database support equipment application;
* The flatness of both ends is required to be better than 0.1mm, and the angle between the two ends and the horizontal plane does not exceed 0.15R/L radian, where R is the bolt radius, L is the bolt length, and the anti-corrosion paint thickness does not exceed 0.3mm.
Remarks: The detection accuracy mainly depends on the bolt calibration parameters entered by the user. In addition, a charging service for specific bolt axial force parameter tension machine calibration or a bolt cloud database experience parameter charging service is provided.
