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.


  • Maximum load
    Standard: 100 lbFin [11.5 Nm]
    Optional:  200 lbFin [22.0 Nm]
  • Digital display of angle
  • Programmable angle limits
  • Angle dial with 2° resolution
  • Computer Control
    An RS-232 port is provided to interface with a PC. A command set is provided to allow for full control from a PC.
    The following are required with PC control:
    - Model 7i or 5i force/torque indicator (more info)
    - AC1108 multi-function cable (see below)
    - AC1104 serial cable (see below)
  • Digital Angle Indication
    Rotational travel is indicated in degrees or revolutions, with RS-232 output of angle data.
  • Programmable Angle Limits
    The TSTM-DC can stop at or cycle between programmable upper and lower angle limits. Programmable in degrees or revolutions.
  • Overload Protection
    Protects the torque sensor against overload (requires a Model 7i or 5i force/torque indicator and AC1108 multi-function cable). The user programs the desired percentage of full scale of the sensor.
  • Auto-return
    The torque table rotates to an angle limit or torque set point (requires a Model M7I or M5I force/torque indicator and AC1108 cable), stops, and reverses direction at full speed to the other angle limit or torque set point.
  • Cycling / Dwell Time
    Same as auto-return, but with the ability to program up to 100,000 cycles. Programmable dwell time for upper and lower limits (set independently) can be set up for up to 10,000 seconds. Independent CW and CCW speeds may be programmed.
  • Programmable Button Functions
    Programmable CW and CCW button functions - momentary motion, maintained motion, or auto.
  • Independent CW and CCW Speeds
    Configurable speeds for CW and CCW directions
  • Selectable speed units of measurement (RPM and °/s)
  • Password protection
    Prevents unauthorized changes to controller settings.

* Maximum torque is 100 lbFin [11.5 Nm] until 15 RPM, then decreases proportionately with speed, as follows:
- Maximum torque at 30 RPM = 50 lbFin [5.6 Nm]
- Maximum torque at 60 RPM = 25 lbFin [2.8 Nm]


  • 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].
