Torque Wrench Calibration System – Automated

Model No: TWC-205
Available Capacities: 1kNm, 3kNm
Steering Effort

Torque wrench calibration system automated 205 Sushma’s torque wrench calibrator as per ISO 6789:2017-2 for static torque tools is the automatic torque wrench calibration system that is built as per the complex ISO standard.


The design ensures that the user can utilize the system adeptly with minimal exposure to it.

The systems require very limited training or experience to operate. It allows the user to learn hands-on in a simple and straightforward manner.


The torque wrench is placed on the Sushma Torque Sensor-Reaction type and held by the adjustable tool holding fixture, enabling perfect horizontal alignment, connected to the rigid reaction bar.

The connection between the torque tool and the tool holding fixture is designed to ensure self-alignment, and reduce parasitic forces, and moments to minimum levels, helping in a better reading of uncertainty.


The main rigid torque loading rig consists of the servo motor driven system with a highly precise gearbox that rotates the sensor in turn loading the torque wrench. The 7-inch touch Smart Control & Display Unit controls the entire machine and gives the user automated & guided instructions to help take action. It also has a database to quickly recalibrate the tool without having to type all the details again (it can be coupled with the optional barcode scanner). The results from the test are then stored on the device, which can be viewed on the display or downloaded to a PC through a USB or pen drive.

You can upgrade the System at any time by simply purchasing the PC Software & PC Package. After performing all uncertainty calculations, the user can print calibration reports using the PC software included in the upgrade pack. To confirm the calculations for uncertainty, it also has an audit mode.

The TWC-205 is also future-ready or comes with the Internet of Things (IOT) Ready features enabling it to connect to the Online Sushma Analytics Platform which will allow for further analysis from various mobile devices that can be used for Quality, Productivity, Research, or any other decision-making process.
