Torque Detector TH-3000

TH-3000 series is a torque detector designed for very low torque (less than 2 N· m) with high response and high accuracy. Two types are available depending on your applications.

 

The TH-3000 series is standard type, and the TH-3000H is for high speed rotation.

It enables accurate torque detection from small precise machines and other machineries with high resolution. Excellent at response, torque ripple produced in actual rotation speed can also be measured.

 

The TH-3000 series works for development of a small rotating object which is required energy efficiency and noise-free. Selectable from rated torque 0.05 N· m, 0.2 N· m, 0.5 N· m or 2 N· m.

TH-3000/3000H series is used in combination with the TS-2800 Digital Torque Meter.


Features

· High speed response
Up to 5 kHz of torque variation can be detected. (*1)

· Available up to 25,000 r/min of rotation speed. Best suited to performance test of small motors
TH-3000H series: High-speed type, 25,000 r/min of rated torque
TH-3000 series: Standard type, 15,000 r/min of rated torque

· High accuracy
Measurement in high accuracy of ±0.2 %/F.S. (*2)

· Overload-resistant mechanism
The original overload-resistant mechanism is adopted to protect the high sensitive detector from overload torque. It can withstand against up to 3 Nm of overload torque. (*3)

· Line driver output having great noise resistance
Line driver output with strong noise immunity. Suitable for in-line use.

· Matching is not necessary at changing cable length
The matching is not required when the cable length is changed. Up to 50 m of cable can be used.

· Compatible size with MD series
Easy replacement from Ono Sokki’s long selling torque detector MD series. It has same outer dimensions to the TH-3000/3000H series.

· Easy coupling
Easier to mount coupling because the shaft length to be used has become longer than the previous models.

· High durability
Non-contact detection. No moving part brings ease of maintenance and less trouble.
(*1) Due to output characteristics of torque meter. The TH-0511 High-speed analog output function (option of the TH-5100 torque meter) is required. The value can be restricted by torsional resonance of equipments.
(*2) Static calibration (average per second)
(*3) The value is maximum overload that the TH-3000 series can withstand when an instantaneous torque is applied, not the maximum value to be used continuously.

Application example

Testing torque characteristics of small motors (T-N characteristic, torque ripple, cogging torque, pull-in/pull-out torque)
Measuring torque ripple at actually used rotation speed.
Measuring high precision motor efficiency
Measuring transient torque at start-up and stop
Measuring constant/changing torque of driving sections such as motors or rollers in precision equipments. (O.A. equipment or camera etc.)

Application

Tracking analysis of torque ripple from a small motor
