The ESM-DC Advanced Motorized Force Measurement Test Stand offers all the mechanical specifications of the ESM motorized test stand, including 200 lb (1 kN) force capacity, modular design, stepper motor design that prevents speed variation with load, and more. The ESM-DC offers expanded capabilities, including an extended speed range, PC control capability, programmable cycling, auto return, overload protection, and other features.

• Speed accuracy: ±0.2% of setting, ±0% variation with load
• Remote controller
• Manual travel knob
• Mounting holes for bench mounting
• Removable base plate with 25 #10-32 threaded holes for fixture mounting
• Base may be removed for alternative mounting
• Universal power supply: 80-250 VAC
• CE mark

* Computer Control

An RS-232 port is provided to interface with a PC. The ESM-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 BG force gauge
- 09-1056 serial cable (see Optional Equipment)
- 09-1143 multi-function cable (see Optional Equipment)

* Overload Protection

Protects a force gauge against overload (requires a Series BG force gauge and 09-1143 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 BG 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 BG 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 UP / DOWN Button Functions
UP and DOWN 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 Up and Down Speeds
Programmable independent speeds for up and down 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 ESM001 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 ESM301.


* A wide range of force gauges and gripping fixtures

* Digital travel display
6" [150 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.

* Limit switch kit
Set of upper and lower adjustable solid state limit switches. Repeatable to within 0.001" [0.03 mm].

* Column extensions
Available in 6", 12", 24", and custom lengths

* Multi-function cable, BG gauge to controller
Connects a Series BG 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.

* Serial cable, gauge to PC
Connects a Series BG force gauge with a PC. Bypasses the controller.

* Competitor force gauge mounting kits available
