Model 411

The static torque transducers of the model series TesT 411 with standard square connection are the typically used sensors for static measurements of torque. Between 1 Nm and 5000 Nm 12 graded sensors are available. The torque transducers are durable and suitable for industrial application. The electronic indicator TesT 813 and the industrial amplifier TesT 854 can be used for the evaluation.

Electrical Torque Transducers – Model 411

• Capacities: 1Nm to 5000Nm
• For static reaction torque measurement
• Standard square connection
• Suitable for permanent installation
• In testing machines and production facilities
• High stiffness
• Godd accuracy
• TEDS module integrated inside sensor

The electrical torque transducers of the model series 411 with a standard square connection are excellently suitable for static reaction torque measurements. The sensors that are made of
stainless steel have an aluminum housing and are characterised by their high stiffness and good accuracy. They are suitable for permanent installation. A TEDS module is already intergrated inside the device.
