TH-3000 Series Torque Detector
Features
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
