Torque Station Pro TS-8700

Previous slide
Next slide

TS-8700 Torque Station Pro is torque measurement system for motor basic property with high precision and high response.
In combination with the motor torque detector MT series with the TH series torque detector, it is possible to perform high-precision, high-response motor torque measurement with up to 5.12 kHz sampling and ± 0.1 % of accuracy.
In addition, the high rigidity compact torque detector RH series (10 N・m/ 20 N・m) can be mounted on the MT series. It has achieved more highly accurate measurement with ±0.05 %/F.S.
This system is ideal for measuring torque fluctuations of motors on-board such as EPS motors.

  • Switching function of motor torque detector is built-in.
  • 2 channels as standard, up to 4 channels as options
  • Link function with OC-1300 series, OS-2000 series to help effective data processing from measurement to data organization
  • Various types of detectors (MT series) for the TS-8700 are available to support various motor characteristic measurement
  • Selectable from three series according to the purpose; for high speed rotation motor, large capacity motor, and torque ripple/cogging torque. There are three types including general, high performance and high precision, and 58 models in total.


High precision/ high response

When combined with the MT detector with the TH type torque detector, the torque measurement accuracy is ± 0.1% and the maximum sampling frequency is 5.12 kHz.
In addition, a new compact high-rigidity torque detector RH type can be mounted. The RH type torque detector (10 Nm / 20 Nm) is a torque detector that achieves high accuracy (± 0.05% F.S.) and high rigidity (4.5 times that of our existing models). It enables to measure torque fluctuations of motors in a higher frequency range with higher accuracy.


Temperature measurement*, temperature trigger measurement*

8ch temperature measurement with a T-type thermocouple, and temperature trigger function are optionally supported. They allow starting measurement automatically after warm-up operation.


Rotation angle measurement*, rotation angle sampling*

>Rotation angle and angle sampling are measured by using the pulses from encoder built-in a target motor. When an encoder is optionally added to the MT-82 T/M (except certain models) detector for cogging torque/torque ripple measurement, rotation angle and angle sampling can be measured in units of 0.1°.

Link function to OC-1300 series Graph creation software, and OS-2000 series Time series data analysis software

Data of measurement result can be transferred to OC-1300 series and OS-2000 series immediately by link function. You can transfer data of measurement results by the link button.
•Efficient and speedy report creation by using a template of OC-1300 series, such as a calibration certificate or others.
•Data evaluation in same time axis by OS-2000 series
The torque data measured by TS-8700 and the sound/vibration data recorded by DS-3000 can be evaluated in the same time axis on the OS-2000 series with this link function.
•Further analysis including FFT analysis can be performed as a secondary processing with the OS-2000 series.

Link function to DS-3000 series

Using this function, you can make measurement start/stop the DS-3000 synchronizing with those timing of TS-8700.
(Using EXT SEQUENCE2 as a DS synchronization signal can reduce the influence of the delay in recording start due to communication, compared to Link measurement on a LAN connection.)

Data communication with a power meter made by other company*

The measurement data of the following four specified power meters made by other companies can be saved digitally via LAN connection.
