The TSTM-DC is an advanced motorized torque test stand offering all the mechanical specifications of the TSTM. The test stand is designed for a wide variety of applications requiring up to 100 lbFin of torque, including closure torque testing, fasteneer torque testing, and more. Modular design allows the stand to be configured for a variety of torque sensors and gripping fixtures while a lever-operated slider with travel stops makes engaging and disengaging samples quick and efficient. The stand includes a torque loading plate with tapped holes for grip and fixture mounting. Stepper motor design eliminate speed variation with load. The TSTM-DC's controller adds a significant amount of sophistication, including integrated angle display and output, programmable angle travel limits, an extended speed range, PC control capability, programmable cycling, auto return, overload protection, and other features.

Computer Control A bi-directional 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 BGI force/torque gauge
• 09-1056 serial cable (see Optional Equipment)
• 09-1143 multi-function cable (see Optional Equipment)
Digital Angle Indication Rotational travel is indicated in degrees or revolutions, wtih 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 overlaod (requires a Model BGI force/torque gauge and 09-1143 multi-function cable). The user programs the desired percentage fo full scale of the sensor.
• Auto-return The Torque table rotates to an angle limit or torque set point (requires a Model BGI force/torque gauge and 09-1143 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 the number of cycles up to 99,999 cycles. Dwell time allows the operator to program the length of time, up to 9,999.9 seconds, in 0.1 second intervals, for which the torque table pauses between cycles. Independent CW and CCW speeds may be programmed.
• Programmable CW/CCW Button Functions CW and CCW button operation can be configured in three user-configurable modes: Maintained: a short push produces continuous motion until STOP is pressed, Momentary: crosshead moves only while the button is pressed, and Auto: short push produces maintained motion, while holding down the button will produce momentary motion.
• Independent CW and CCW Speeds Programmable independent speeds for clockwise and counterclockwise directions
• Selectable Speed Units of Measurement (RPM and deg/s)
• Password Protection Prevents unauthorized changes to test parameters
