Digital Torque Meter
TS-2800

The TS-2800 is a torque calculation display device used in combination with our phase difference torque detectors, including the SS series.

It supports both the long-selling SS series torque detectors (potential gear phase difference method) and the TH series torque detectors (electromagnetic induction phase difference method).
Since all signal processing circuits are digitally processed, it enables torque measurement with excellent stability, reproducibility, and linearity.

The TS-2800 can display measurement values digitally and output analog voltage, rotation pulses*, BCD*, and RS-232C externally.

It is compact, so it does not take up much space even when installed on measurement panels. It also fits neatly next to control devices within the panel.
*Optional

Features

  • All of our phase difference method torque detectors can be connected.

  • You can select the responsiveness (time constant) of the analog output according to its intended use.

  • A 4th order Butterworth type low-pass filter can be selected for torque ripple frequency analysis (TH mode, optional).

  • You can select the full-scale voltage of the torque output signal to match the input range of the connected devices or recorders.

  • It can output the rotational pulse signal necessary for torque ripple rotational tracking analysis (optional).

  • The adoption of an LCD screen has made measurement values and settings menus easier to see, improving operability.

Case Studies

Torque ripple of small motors at different rotational speeds (rotational speed tracking analysis)

The torque of the motor fluctuates repeatedly with a constant period and width due to changes in the number of magnetic flux chains in the motor. Torque ripple refers to the range of torque fluctuations during motor rotation. By understanding the torque ripple at different rotational speeds, solutions can be derived for issues related to noise and vibration generated by the motor, as well as deterioration in controllability.

Evaluation of hinge torque characteristics for OA equipment and mobile phones.

We measure the torque characteristics of hinges used in various fields, such as household appliances like rice cookers and microwaves, office equipment like FAX machines and copiers, as well as mobile phones and laptops.

  • Management of the force required for opening and closing.

  • The changes in hinge characteristics after long-term use due to tens of thousands of opening and closing tests are effective for automation and labor-saving.
