Motorized Tension / Compression Test Stand
To be discontinued October 1, 2023
The ESM303H is a highly configurable horizontal force tester for tension and compression measurement applications up to 300 lbF [1.5 kN], with a rugged design suitable for laboratory and production environments. Sample setup and fine positioning are a breeze with available FollowMe® force-based positioning - using your hand as your guide, push and pull on the load cell to move the crosshead at a variable rate of speed.
With generous travel, clearance, and depth dimensions, a wide range of tests can be performed, including break testing, cycling, limit testing to a load or distance, loadholding, elongation testing, tensile testing, compression testing, and more. Satisfy various test methods through an easy-to-use menu, allowing the configuration of test speed, force and distance limits, cycling, preload, and many other functions, all protected by a password. Save up to 50 profiles to accommodate a range of test methods.
When the ESM303H’s clearance is insufficient for the application, its modular mechanical design allows for frame extensions. Modularity extends to the controller functions as well. Individual functions, such as travel measurement, cycling, loadholding, etc., may be purchased either upfront or enabled in the field through an activation code. This a-la-carte platform allows for custom configuration as appropriate for the application and budget.
Collect force and travel data, plot and analyze the results, and control test stand motion via PC-based MESUR®gauge Plus software. Or, fully control the stand by a PC through a custom-written program in any language supporting ASCII communications.

Any of the below functions may be purchased at time of order or may be enabled in the field at a later date via a code activation process. The only exception is the AF009 travel measurement option, which additionally requires field hardware installation.
A complete options package is also available, including all of the below functions at a discounted price. The test stand is shipped in Demo Mode, during which time all available functions are temporarily enabled for 160 hours of operation.
|FollowMe®||AF008||Crosshead movement responds to manually pushing or pulling on the load cell. Increasing force produces greater speeds. Ideal for setups and quick positioning.||
|Travel indication||AF009||Travel is indicated on the control unit display, with output via USB. An internal scale utilizing Renishaw technology produces significantly higher accuracy than with conventional rotary encoder-based designs. Backlash and nonlinearity are virtually eliminated.||
The ESM303H may be fully controlled by a PC through a program written in any language supporting ASCII communications. Also responds to the legacy Chatillon TCD command set and legacy Nexygen TCD software (not available from Mark-10).
This option is not required for MESUR®gauge Plus software.
|Programmable travel limits||AF011||The stand stops at or cycles between programmable right and left travel distances.||
|Overload protection||AF012||Protects a load cell against overload. Program the desired percentage of full scale of the load cell. Adjustable analog voltage setting allows the stand to interface with virtually any instrument with analog output.||
|Auto return||AF013||The crosshead moves to a limit switch, force set point, travel position, or break, then stops and reverses direction at full speed to the opposite limit.||
|Cycling / dwell time||AF014||Same as auto return, but with the ability to program up to 100,000 cycles. Programmable dwell time for right and left limits (set independently) can be set up for up to 10,000 seconds.||
|Independent right and left speeds||AF016||Configurable speeds for right and left directions.||
|Low speed extension||AF017||Extends the standard speed range down to 0.02 in/min (0.5 mm/min).||
|High speed extension||AF018||Extends the standard speed range up to 45 in/min (1,100 mm/min).||
|Break detection||AF019||Crosshead stops at a sudden drop in force. Programmable percentage of peak force.||
|Loadholding||AF020||Dynamically adjusts the crosshead position to maintain a programmed load for an indefinite or specified period of time.||
|Preload / sample touch||AF021||Stops the crosshead and/or zeroes the travel display at an initial preload - useful in tensile, compression, spring, elongation, and other applications. Preload is programmable as a percentage of force gauge/load cell full scale. Three modes: (1) stop, (2) stop and zero, and (3) zero without stopping.||
|Profiles||AF022||Save and recall sets of test parameters, such as speeds, travel limits, preloads, etc. Up to 50 profiles may be stored.||-|
|Complete options package||AFCOMP-H||Includes all functions listed above, plus AC1115 interface cable and AC1107 USB cable.
Requires a Model M7I or M5I indicator.
