ESM301/ESM301L Motorized Test Stands With PC Control

The ESM301 and extended length ESM301L are highly configurable motorized test stands for tension and compression testing applications up to 300 lbF (1.5 kN) for laboratory and production environments.

The stands can perform a wide range of tests, including break testing, cycling, limit testing to a load or distance, load holding, 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. The stands can be controlled via its console or PC.

Functions are offered individually through a unique "build-your-own" configuration platform. Order any combination of functions to customize the stand to specific requirements. Functions not ordered originally can be activated in the field.

A password can be set to protect against unauthorized changes. Modular mechanical design allows the test frame and controller to be separated for various mounting configurations.

  • A wide range of force gauges and gripping fixtures
  • Multi-function cables, gauge to controller (09-1162)

  • Column extensions (ESM301-002-1, -2, -3)
    A spacer is supplied between the base and the column, increasing clearance between the force gauge and base (does not increase travel distance). Available in 6" (150 mm), 12" (300 mm), and 24" (610 mm), and custom lengths. Bench mounting kit is recommended
  • Frame-Controller connection cables (09-1137, -1, -2, -3)
    Permit the removal of test frame from controller for alternative mounting configurations.
  • Competitor force gauge mounting kits
  • Eye end adapters
    Allow for quick grip installation and removal, and prevent grip rotation. Mount to common test frames, load cells, and force gauges


Most of the below functions may be purchased at time of order or may be enabled in the field at a later date though a simple activation process. A complete options package is also available, including all of the below features at a discounted price. The stands are shipped in Demo Mode, during which time all available features are enabled for 160 hours of operation.

Feature Part No. Description Requirements
Travel indication ESM301-001
Travel is indicated on the front panel, and an RS-232 port is supplied. Position indication is provided via an internal linear scale, producing significantly higher accuracy than with conventional rotary encoder-based designs. Backlash and nonlinearity are virtually eliminated.
  • Order upfront, not field installable
EF010 A bi-directional RS-232 port is provided to interface with a PC. Users can write a custom program utilizing a library of ASCII commands or control the stand via a PC using legacy Nexygen TCD software (not available from Mark-10).
  • Series 5 or 7 force gauge
  • 09-1056 serial cable
  • 09-1162 cable
  • ESM301(L)-001 integrated travel indication
  • EF011 programmable travel set points
travel limits
EF011 The ESM301 can stop at or cycle between programmable upper and lower travel distances.
  • ESM301-001 or
    ESM301L-001 travel indication option
EF012 Protects a force gauge against overload. Program the desired percentage of full scale of the gauge. Adjustable analog output voltage setting allows the ESM301 to interface with virtually any gauge with analog output.
  • Series 7, 5 or 4 force gauge
  • 09-1162 cable
Auto Return EF013 The crosshead moves to a limit switch, force set point, travel position, or break, then stops and reverses direction at full speed to the other limit.
  • Reversing at force set point: Series 7, 5 or 4 force gauge and 09-1162 cable
  • Reversing at travel limit: EF011 programmable travel limits option
  • Reversing at break: EF019 break detection option and 09-1162 cable
Cycling / dwell time EF014 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.
  • Same as auto-return. Requires EF016 for independent up and down speeds.
Independent Up
and Down Speeds
EF016 Configurable speeds for up and down directions. -
Low Speed
EF017 Extends the speed range to
0.02 - 13 in/min (0.5 - 330 mm/min).
High Speed
EF018 Extends the speed range to
0.5 - 45 in/min (13 - 1100 mm/min).
Break Detection1 EF019 Crosshead stops at a sudden drop in force. Programmable
percentage of peak force.
  • Series 7 or 5
    force gauge2
  • 09-1162 cable
Load Holding1 EF020 Dynamically adjusts the crosshead position to maintain a
programmed load for an indefinite or specified period of time.
  • Series 7 or 5
    force gauge2
  • 09-1162
  • If a specified time is required, order EF014 cycling option
Preload / Sample Touch EF021 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 full scale. Three modes: (1) stop, (2) stop and zero,
and (3) zero without stopping.
