The 100 lbF (500 N) capacity ESMH-DC Advanced Motorized Force Measurement Test Stand offers all the mechanical specifications of the ESMH motorized test stand, including smooth top surface ideal for coefficient of friction testing, integrated limit switches, stepper motor design that prevents speed variation with load, and more.

The ESMH-DC offers expanded capabilities, including PC control, programmable cycling, auto return, and other features.

Optional Equipment


Digital travel display

12" [300 mm] travel, 0.0005" [0.01 mm] resolution, 0.001" [0.03 mm] accuracy, SPC output for automated data collection. For output of travel data to a PC, the following items are required: 09-1066 cable and MRS100A communication adapter. Note: continuous data output rate is limited to 2 Hz.





Multi-function cable, gauge to controller 
Connects a Series 4, 5, or 7 force gauge to the controller. This single cable is used to transmit set points, overload signals, and force data.

Serial cable, controller to PC
Bi-directional communication with a PC for computer control. Also sends force data from the controller to a PC.

RS-232 to USB adapter
Converts RS-232 to USB output. Includes USB cable and installation CD.



Eye End Adapters

Allow for quick grip installation and removal, and prevent grip rotation. Mount to common test frames, load cells, and force gauges




Controller Features/Specifications

Computer Control
An RS-232 port is provided to interface with a PC. The ESMH-DC accepts a number of commands pertaining to test stand motion and force gauge functions*. The following additional items are required for PC control:

• Series 5 or Series 7 force gauge
• 09-1056 serial cable (see Optional Equipment)
• 09-1162 multi-function cable (see Optional Equipment)

Overload Protection
Protects a force gauge against overload (requires a Series 4, 5, or 7 force gauge and 09-1162 multi-function cable). The user programs the desired percentage of full scale of the gauge. Adjustable analog output voltage setting allows the test stand to interface with virtually any force gauge with analog output.

Auto-return 
The crosshead moves to a limit switch or force set point (requires a Series 4, 5, or 7 force gauge), stops, and reverses direction at maximum speed to the other limit switch or set point.

Cycling / Dwell Time 
The crosshead moves up and down between limit switches or force set points (requires a Series 4, 5, or 7 force gauge). Configurable up to 99,999 cycles. Dwell time allows the operator to program the amount of time, up to 9,999.9 seconds, in 0.1 second intervals, for which the crosshead pauses at limits.

Programmable LEFT / RIGHT Button Functions
LEFT and RIGHT 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 Left and Right Speeds 
Programmable independent speeds for left and right directions

Selectable speed units of measurement (in/min & mm/min)

Password protection
Prevents unauthorized changes to test parameters

* Contains no integrated travel measurement. Travel information available only through the external ESMH001 digital travel display, requiring an additional serial port on the PC. For an integrated solution with full PC control, including travel distance, see test stand model ESM303.
