Understanding MTX Torque Sensors
What Is an MTX Torque Sensor?
The MTX is a reaction torque sensor designed to measure applied torque during testing and verification activities.
Unlike a rotary torque sensor, a reaction torque sensor remains stationary while measuring torque applied to the sensor.
Why Use a Reaction Torque Sensor?
Reaction torque sensors are commonly used when torque measurement is required without rotation of the sensor body.
They are frequently used in:
- Calibration applications
- Torque verification programs
- Hand tool testing
- Power tool testing
- Quality control environments
What Makes the MTX Different?
The MTX combines the following features to support testing, calibration, and verification applications:
- Reaction torque measurement
- Compatibility with Mountz torque analyzers
- Multiple torque capacities
- Support for calibration activities
- Support for quality control programs
Reaction Torque Sensors vs. Rotary Torque Sensors
Mountz offers both reaction torque sensors and rotary torque sensors.
Reaction Torque Sensors (MTX)
Reaction torque sensors remain stationary while measuring applied torque. They are commonly used for:
- Torque verification
- Calibration activities
- Hand tool testing
- Quality control inspections
Rotary Torque Sensors
Rotary torque sensors are designed to measure torque while rotating and are commonly used for:
- Power tool testing
- Rotary applications
- Torque and angle measurement applications
Selecting the appropriate sensor depends on the application requirements and testing method.
Available Models
MTX Torque Sensor Models
The MTX Series includes low-torque reaction sensors designed for torque testing, calibration, and verification of hand screwdrivers, torque wrenches, and power tools. Each model is optimized for a specific torque capacity while maintaining the same 1/4" female square drive interface. All MTX sensors are mountable, bi-directional, feature ARC II auto-recognition technology, and include an ISO 17025 Certificate of Calibration.
How MTX Models Are Specified
Each MTX model is named according to its maximum torque capacity.
For example:
- MTX10z measures 1–10 ozf.in
- MTX80z measures 8–80 ozf.in
- MTX160z measures 16–160 ozf.in
Selecting the smallest sensor that fully covers your expected torque range typically provides the best measurement resolution and accuracy.
Model Selection Guide
Need ultra-low torque measurement?
Choose:
- MTX10z
Ideal for micro-torque screwdrivers and delicate fastening applications.
Need low-torque screwdriver testing?
Choose:
- MTX20z
- MTX40z

Which MTX Model Should I Select?
Consider the following when choosing an MTX sensor:
- What is the maximum torque you need to measure?
- Are you testing hand screwdrivers or power tools?
- Will the sensor be used for calibration, verification, or production testing?
- Do you want the highest possible measurement resolution?
- Are you using an LTT or PTT torque analyzer?
- Will a run-down adapter be required for power tool testing?
Selecting a sensor whose operating range closely matches the expected application provides the best measurement performance. Mountz also recommends using a run-down adapter when testing power tools.
