One Solution for Multiple Sensors

Eliminate compatibility issues and reduce system complexity. A single amplifier supports a wide range of force and torque sensors, minimizing spare parts and simplifying commissioning.

Built‑In Intelligence Saves Time

Torque/speed and torque/rotational angle measurements are evaluated directly by the unit. Mechanical power is calculated automatically and displayed in real time—no external software or post‑processing required.

Capture What Matters Most

Integrated peak detection and extreme‑value monitoring ensure critical load conditions are never missed, helping protect equipment and improve product quality.

Proven Performance, Anywhere You Need It

Designed for both high‑volume production environments and precise test and laboratory applications, the amplifier delivers consistent, dependable results wherever accuracy matters.

Torque is measured directly using high‑accuracy strain gauge technology, delivering reliable and repeatable results across the entire measuring range. Measured values are transmitted digitally and contactless from rotor to stator, eliminating wear, minimizing maintenance, and ensuring long‑term signal stability—even in continuous operation.

Intelligent Measurement Built In

The integrated measurement amplifier evaluates:

• Torque / speed
• Torque / rotational angle

Mechanical power is calculated automatically by the unit and displayed in real time, providing immediate insight without the need for external calculation or additional software.

Wide Measuring Range with Dual Calibration

• Rated torque range: 100 Nm to 20,000 Nm
• Second, independently calibrated measuring range: 1:5 or 1:10

This dual‑range concept delivers high resolution for low‑torque measurements while maintaining full rated capacity—maximizing accuracy and flexibility without changing hardware.

Flexible Outputs & Easy System Integration

Both analog and digital output signals are available, enabling seamless integration into:

• Test benches and data acquisition systems
• PLCs and automation systems
• Production monitoring and quality control environments

Integrated digital inputs and outputs support efficient process control and automation.

Capture Critical Data with Confidence

Built‑in circuitry for:

• Extreme‑value and peak measurement
• Measurement curve recording and storage

ensures that critical load conditions are captured reliably—supporting quality assurance, traceability, and documentation requirements.

A key advantage of the KiTorq® System is its flexibility. Rotors and stators with the same speed rating are fully compatible and interchangeable, allowing users to easily configure, expand, or replace system components as required.

The modular design simplifies system integration, reduces spare-parts requirements, and provides a dependable solution for test benches, industrial drives, and research applications.

Key Features

• Modular torque measurement system
