High-Precision Electric Torque Sensor for Drilling & Industrial Automation | CNPS

The sensor measures torque continuously in both static and dynamic applications, converting mechanical torque loading into stable electrical signals. CNPS rotational torque sensor models are specifically designed for dynamic shaft measurement, supporting rotational speeds up to 50,000 rpm. Signal conditioning provides true RMS measurement with wide bandwidth and AC/DC compatibility, and the result is delivered through voltage, current, USB or CAN bus outputs for real-time monitoring and process control.

• High accuracy up to ±0.05% FS — Provides trustworthy torque data for quality control and process optimization decisions.
• Wide torque coverage from micro loads to heavy industrial torque — One platform spans laboratory testing and high-load mechanical applications; confirm the exact range by model.
• Rotational speed up to 50,000 rpm — Enables accurate dynamic torque measurement on high-speed rotating shafts.
• Multiple outputs: voltage, current, USB, CAN bus — Plug-and-play compatibility with modern test benches, production lines, and automation systems.
• Sturdy stainless steel casing with IP65 protection — Withstands mud, dust, and drilling vibrations in the field.
• Overload capacity up to 200% FS — Protects the sensor against overload conditions and extends service life.
• Clamp design for quick installation — Sensor modifications can be made without stopping the machine, minimizing production downtime.
• Intrinsically safe model complies with EX/EN safety requirements — Suitable for hazardous-area installations where safety compliance is required.

Summary: The CNPS electric torque sensor is mounted onto the shaft or drive train using a clamp design, so it can be fitted or modified without stopping the machine. It captures torque loading in static and rotating shafts and converts it into a stable electrical signal for continuous monitoring.
