Product catalog summary

Overview of ETH-Messtechnik GmbH
ETH-Messtechnik GmbH, founded in 1987, specializes in torque sensors, test benches, and accessories. Certified under DIN EN ISO 9001, they offer both active and passive torque sensors with measuring ranges from 0.02 to 20,000 Nm, along with customized solutions and accessories like couplings and cables.

Product Offerings

Torque Sensors: Designed with cylindrical or square/hexagonal connections for tool integration.
Test Benches: Custom-built to customer specifications.
Supply and Evaluation Devices: For sensor analysis and monitoring.
Accessories: Includes couplings and cables.

Types of Couplings

Nickel Bellows Couplings: Torque range from 0.2 to 500 Nm, easy installation.
Metal Bellows Couplings: Torque capacities from 0.05 to 1500 Nm, compact design.
Safety Couplings: Adjustable torque, high clamping forces, range from 0.1 to 2800 Nm.
Elastomer Couplings: Vibration dampening, torque up to 25,000 Nm.
Spring Disc Couplings: For misalignment compensation and vibration dampening.

Technical Specifications
Specifications include torque range, material composition, temperature range, installation features, and misalignment tolerances. Models are described with features like backlash-free operation and high torsional stiffness.

Installation and Usage Guidelines
Adherence to specified axis offsets is crucial for optimal performance and damage prevention, with maximum allowed offsets for radial, axial, and angular misalignments provided.

Conclusion
ETH-Messtechnik GmbH offers a wide range of torque sensors and couplings, characterized by innovative design, precision, and reliability, supported by detailed technical specifications and customization options.

Metal Bellows Couplings
Models include KB2P, KB4, KB4AL, KB4C, KB4H, and KB4HC, with torque ranges from 0.5 Nm to 1400 Nm. Made from stainless steel bellows and aluminum or steel hubs, they operate within -30°C to 120°C, with some up to 250°C.

Safety Couplings
Protect components from overload with adjustable disengagement torque and spring-loaded mechanisms. They offer single or multi-position re-engagement and full disengagement options.

Elastomer Couplings
EK2, EKL, and EKH models feature easy mounting, high concentricity, and vibration damping, with rated torque from 6 Nm to 25,000 Nm.

Spring Disc Couplings
FSXK model offers backlash-free transmission with high torsional stiffness and vibration damping, suitable for high speeds.

Company Information
Located in Gschwend, Germany, ETH-Messtechnik GmbH has expanded its production facilities to enhance manufacturing capabilities.
