Photo (TS-2800 Torque Meter)




The TS-2800 is a torque meter for phase difference type torque detectors. Can be used with our long-selling torque detectors SS/DD series and high accuracy, high response type TH series. Since all signals are digitally processed, torque measurement can be performed with great stability, reproducibility and linearity.


The TS-2800 can output analog voltage, rotation pulse*, BCD*, and RS-232C as well as displaying measurement values digitally. Compact and space-saving design is enough to fit your measurement system yet the installation space are limited.

*: option


· Can be connected all of phase difference type torque detectors by Ono Sokki.

· Analog output response (time constant) can be selected depending on your application.

· 4th order butterworth low-pass filter can be selected for analyzing frequency of torque ripple. (TH mode, option)

· F.S. voltage of torque output can be selected according to the input range of a recorder or other devices to be connected.

· Output of rotation pulse signal required for rotation tracking analysis of torque ripple

· Easy to read, easy to operate with LCD.

Measuring torque ripple for each rotation speed of a small motor. (Tracking analysis of rotation speed)

Motor torque varies repeatedly with constant period and constant width due to interlinkage magnetic flux. The difference between the maximum and the minimum torque compared to the average torque is defined torque ripple. Measuring torque ripple arrives at solution for sound and vibration problems, and less ability to control caused by electromotive force.

Checking hinge torque characteristics of OA equipment, cell phones etc.

This example shows how to measure the torque characteristics of hinges used in various products such as electric home appliance (rice cooker or microwave), OA equipment (fax or copy machine) and PCs or cell phones. Measuring torque characteristics is used to control product quality. For example, it is effective in checking whether hinges meet specific requirements and characteristics or not.

• Checking the force required to open and close
• Checking the changes of hinge characteristics after tens of thousands of opening and closing tests
