Torque Sensor Dynamic Wireless Non Contact Type

About Torque Sensor Dynamic Wireless Non Contact Type

The TTD Non-Contact Dynamic Torque Transducer is a CE-certified rotary torque sensor designed for accurate torque measurement in rotating shafts and industrial equipment. Unlike slip-ring models, this version uses wireless radio telemetry, eliminating mechanical signal transfer and ensuring low-noise, maintenance-friendly operation.

Constructed from hardened Stainless Steel 17-4 PH, the sensor operates on the strain gauge principle with built-in measuring circuit, ADC, microcontroller, and RF transmitter. The torque shaft houses a rechargeable Li-Ion battery (approx. 20 hours runtime), transmitting real-time torque data to a stationary receiver with LED display.

It supports speeds up to 5000 RPM and offers capacities from 20 Nm to 50 kNm, making it suitable for high-speed dynamic torque testing in industrial and automotive environments.

Frequently Asked Questions (FAQs)

1. What makes this torque transducer non-contact?

It uses radio telemetry transmission instead of slip rings or brushes, eliminating mechanical contact for signal transfer.

2. What is the working principle?

It operates on the strain gauge principle, where torsional strain in the shaft is converted into an electrical signal. The built-in electronics convert and transmit the signal wirelessly.

3. What is the maximum rotational speed?

It supports speeds up to 5000 RPM, depending on capacity.

4. What is the battery backup?

The inbuilt rechargeable Li-Ion battery provides approximately 20 hours of runtime per charge.

5. What is the transmission distance?

The transmitter can send signals up to 15 meters to the receiver.

6. What is the operating temperature range?

• Operating Temperature: 0C to 50C

• Temperature Compensated Range: 10C to 50C
