Series TSTM-DC

Advanced Motorized Torque Test Stand

Series TSTM-DC advanced motorized torque test stands are designed for a wide variety of applications, including closure torque testing, fastener torque testing, and more. Two torque capacities are available, 100 lbFin (11.5 Nm) and 200 lbFin (22 Nm).

The stands include a torque loading plate with tapped holes for grip and fixture mounting. Stepper motor design eliminates speed variation with load. A lever-operated slider with travel stops makes engaging and disengaging samples quick and efficient. A modular mechanical design allows the stand to be configured for a variety of applications.

The controller features an integrated angle display and output, programmable angle travel limits, PC control capability, programmable cycling, auto return, overload protection, password protection, and more.


  • Configurable clockwise and counter-clockwise speeds, RPM or °/s
  • Digital angle indicator
    Rotational travel is indicated in degrees or revolutions, with RS-232 output of angle data.
  • Angle limits
    Stop at or cycle between configurable upper and lower angle limits, in degrees or revolutions.
  • Angle dial with 2° resolution
  • Auto-return
    The torque table rotates to an angle limit or torque limit (requires a Model M7I or M5I indicator and AC1108 multi-function cable), stops, and reverses direction at full speed to the other angle limit or torque set limit.
  • Cycling
    Same as auto-return, but with the ability to program up to 100,000 cycles. Configurable dwell time for upper and lower limits (set independently) can be set up for up to 10,000 seconds. CW and CCW speeds may be set independently.
  • Configurable button functions
    CW and CCW button presses can produce one of the following motions: (1) momentary (button-hold), (2) maintained (button release) , or (3) automatic (press and hold for momentary, or quick press and release for maintained motion).
  • Overload protection
    Protects the torque sensor against overload (requires a Model M7I or M5I indicator and AC1108 multi-function cable).
  • PC control
    Control the test stand with your own application using a supplied library of motion control and data collection serial commands.
    Note the following co-requirements:
    - Model M7I or M5I indicator
    - AC1108 multi-function cable
    - AC1104 serial cable
  • Password protection
    Prevents unauthorized changes to settings.


  • Maximum torque
    TSTM(H)-DC: 100 lbFin [11.5 Nm]
    TSTM(H)-DC-1: 200 lbFin [22.0 Nm]1
  • Speed range
    TSTM(H)-DC: 0.01 – 15 RPM [0.05 – 90°/s]
    TSTM(H)-DC-2: 0.04 – 60 RPM [0.2 – 360°/s]2
  • Speed accuracy
    ±0.2% of setting, ±0% variation with load
  • Rotational travel accuracy: ±0.7° [0.002 revolutions]
  • Rotational travel resolution: 0.1° [0.01 revolutions]
  • Rotational travel repeatability: 0.1° [0.0003 revolutions]
  • Throat: 4.10″ [104 mm]
  • Manual adjustment: 12° / adjustment knob revolution
  • Maximum slider travel: 15.5″ [394 mm]
  • Slider travel rate: 1.047″ [26.6 mm] / lever revolution
  • Universal power supply: 80-250 VAC

1. Maximum torque is proportional to speed. At 200 lbFin [22.0 Nm], the maximum speed is 7.5 RPM.
2. Maximum speed is proportional to torque. At 60 RPM, the maximum torque is 25 lbFin. [2.8 Nm].
