Multi-Component Sensors
There are three different, patented multi-component sensors available:
- Model 201 for 3 components: Clamping force, total torque and frictional torque under the screw head. The frictional torque in the thread is calculated here. This model is the most widely used model for quality assurance.
- Modell 202 for 4 components: Clamping force, total torque, frictional torque under the screw head and frictional torque in the thread. This model is ideal for research and development.
- Modell 203 for 2 components: Clamping force and total torque. This model is recommended for simple QA tasks, for example at surface coating companies, often operated manually.
Features
Technical specifications
By use of these patented multi-component sensors the following parameters will be measured simultaneously, with highest precision and without influence of one parameter to the other:
- The clamping force in the screw during tightening and loosening – all models –
- The total torque during tightening and loosening – all models –
- The frictional torque under the head of the screw – models 201 and 202 –
- The frictional torque in the thread – model 202 (will be calculated at model 201) –
- The necessary angle with a resolution of 0,1° – all electromotive models –
| Model 201 | 3-component sensor | Force + Total Torque + Frictional Torque under the head are measured + (calculated: Frictional torque in the thread) |
| Model 202 | 4-component sensor | Force + Total Torque + Frictional Torque under the head + Frictional Torque in the thread are measured |
| Model 203 | 2-component sensor |
Friction Testing Machines by TesT
Our friction testing machines, equipped with the patented multi-component-sensors have entered the world market. All national and international standards, as well as every company standard specification will be respected. The measured and calculated forces, torques and angles are basics to show the friction coefficients at screws, bolts, nuts and components. Due to these information fixation parts can be used in that way, that an op- timized and safe fixation is assured.
Multi-Component Sensors
The patented multi-component sensors allow measuring the strain occurring by tension force and torque inside the screw individually. They transmit the decoupled measurement values to the force sensor and to the torque sensors. Additionally, the necessary angle will be measured with a high reso- lution inside the machine.
Application areas are primarily in automotive indus- try, at car and truck manufacturers, in fastener in- dustry, big mechanic construction, power engines and particularly for wind power stations.
