Digital Precision Electric Torque Wrenches

Related Introduction

The minimum resolution can reach 1N.m and factory accuracy reaches ±3%. The repeatability accuracy is ±3%, and the accompanying traceability torque verification report is provided. The TS version with torque sensor can achieve an accuracy of ±1%;

The power system can rotate 360 degrees, and the memory-type mechanical locking system has no reactive force acting on the handle, which can prevent personal injury caused by mechanical failure;

Spring type reaction arm can be quickly removed and replaced, improving work efficiency;

After tightening, it can automatically retract, making it easy to remove the wrench;

Lightweight and reliable ergonomic gun grip, increasing user comfort;

The STW-CS series controller provides a simple and easy-to-use operating interface for all STW tools, allowing torque to be set through the human-machine interface, making operation simpler and more convenient;

Workstations, operators, torque, and dates can be edited, and fastening data can also be exported via USB;

It will automatically stop when the set torque is reached, and the tightening result is informed by visual signal light and buzzer;

The counter calculates the number of times it has been used in real-time and maintenance times is set for automatic reminder, making it clear whether maintenance is needed immediately;

There are three modes to choose from: torque mode, angle mode, and torque plus angle mode;

Optional: Transmission system with torque sensor, capable of achieving dual closed-loop control of torque and angle, with TS added to the model;

Support communication methods such as MODBUS and PROFIBUS, and can also add wireless communication modules to achieve management of IoT connection between upper computer and MES system;
