MT series Torque detector / TS-8700 Torque Station Pro

TS-8700 Torque Station Pro is torque measurement system for motor basic property with high precision and high response. Using with the motor torque detector MT series which includes the high accuracy and high response type TH series torque detector, up to 5.12 kHz sampling, ±0.1% of accuracy are achieved.

•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 system according to the purpose; for high speed rotation motor, large capacity motor, and torque ripple/cogging torque. Extensive lineup of 52 models including two types, including general and high performance





TH/TQ* type torque detectors supported

The selection of torque detector used with the MT series torque detectors is expanded. TH type detector is added to lineup (existing model: MD/SS type torque detectors) . TQ type torque detector is also supported as a made-to-order.

High precision•high response *
More precise measurement has been achieved by using TH type detector as the detection part in the MT type detector. (when TH-1000/2000 used: ±0.1 %) 1024 Hz of sampling frequency as standard, high speed sampling of 5120 Hz is possible as option

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.

 •WT1800E, WT300E (WTViewerEfree*1Ver1.42 or later used) : made by YOKOGAWA ELECTRIC
 •PW3390, PW3337 (PW Communicator*2Ver1.7.0 or later used) :Made by HIOKI E.E. CORPORATION


Freely selectable system component

You can select devices according to the torque capacity to be tested or setting place. (Desktop type, Floor type stand with caster, XYZ stage, slide base, V block, L bracket etc.)
*Device to be selected may be limited depending on models or torque capacity. Please consult your nearest distributor or Ono Sokki sales office.
