RS425 torque transducer- Datum Electronics
The Datum Electronics Series RS425 non-contact rotary torque transducers have been designed to fit easily in line with any drivetrain or test bed using either a spline or keyway shaft. The RS425 is a true non-contact torque transducer, the rotor runs inside the stator with 2 to 5 mm gap. This ensures no longterm wear of bearings or frictional loads on the rotating drive shaft.
RS425 System Performance and Benefits:
- Lightweight Torque transducer with completely separate rotor and stator set
- No mechanical friction, long-term operation reduced maintenance
- Ideal keyway shaft for easy fitting to test rigs and drive systems
- Spline shafts are also available as an alternative to a keyway shaft
- No bearings – ideal for high speed applications
- Standard RS425 torque transducer range available from 0-10Nm to 0-30,000Nm
- Analogue Output available & compatible with LABVIEW software
- Ideal for fully sealed or underwater applications (IP 68) system upgrade
RS425 System Advantages
- Accurate On Shaft Torque Measurement
- Flexible shaft fittings (Spline or keyway shaft)
- Modular System Assembly
- Non-contact Signal Transmission
- Proven Technology
- Low Maintenance
- Simple Linear Calibration
- Engineered to fit most drive components
- Rotary and Static Torque Measurement
- Optional Analogue Data Output
- LABVIEW compatible
