The ESM303 motorized force test stand is designed for tension and compression measurement up to 300 lb / 1500 N. Its rugged design is suitable for laboratory and production environments. With generous travel, clearance, and depth, a wide range of tests can be performed, including destructive testing, cycling, limit testing to load or distance, load-holding, elongation testing, tensile testing, compression testing, and more. A simple menu allows the user to program 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. If the ESM303’s clearance is insufficient for the application, its modular mechanical design allows for single and double-column extensions. The ESM303 offers and range of optional functions to extended its capability 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. Force and travel data can be output to a PC for graphing and analysis using MESUR™gauge software. Or, fully control the stand by a PC through a custom-written program with ASCII communication.
Key Features
Simple controller interface Rugged aluminum up/down/stop keys are designed for industrial environments. Zero Travel and FollowMeTM keys add convenience. Removable for remote use. See the following page for a full list of available functions. | |
Limit switches Adjustable upper and lower solid state limit switches stop test stand travel with 0.025 mm repeatability. | |
Adjustable mounting plate with T-slot bas The mounting plate may be repositioned in the X- and Y-directions, for proper sample alignment. Matrix of threaded holes for fixture mounting. | |
Modular design All electronics are installed onto a single panel, easily accessible and removable for updating and service. | |
FollowMe Using your hand as your guide, push and pull on the load cell or force gauge to move the crosshead. Responsive enough for quick positioning as well as fine adjustments. | |
Force gauges Consider a Series 7 or 5 gauge for force vs. time or force vs. travel data output, and to take advantage of all available test stand functions. | |
Grips and eye end adapters Wide range of grips for tensile, peel, compression, and specialized applications. Eye end adapters allow for quick grip installation and removal, and prevent rotation. | |
Indicator / load cell adapter Accommodates any indicator and Series R01 or R03 force sensors. Includes mounting hardware. | |
Single column extensions Increase the vertical clearance for tall samples. Three lengths are available - 150, 300, and 600 mm | |
Double column extensions Accommodate up to a 508 mm wide sample, or ø546 mm round sample. Three heights are available - 150, 300, and 600 mm. Base contains rows of T-slots for fixture mounting. | |
MESUR gauge data collection software Output force vs. time or force vs. distance data from the ESM303’s USB port. MESURgauge graphs, tabulates, calculates statistics, and provides reporting and output tools. | |
Optional Test Stand Functions
Any of the below functions may be purchased at time of order or may be activated in the field at a later date via an activation code. A complete options package is also available at a discounted price. The stand is supplied in Demo Mode, a 160-hour time period in which all functions are temporarily enabled. | Feature | Part
No. | Description |
|---|
| FollowMe™ | AF008 | Crosshead movement responds to manually pushing or pulling on the force gauge shaft or 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. | | Computer control | AF010 | The ESM303 may be fully controlled by a PC through a custom-written program 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). | | Programmable travel limits | AF011 | The stand stops at or cycles between programmable upper and lower travel distances. | | Overload protection | AF012 | Protects a force gauge or force sensor against overload. Program the desired percentage of full scale of the gauge. Adjustable analog voltage setting allows the stand to interface with virtually any gauge 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 upper and lower limits (set independently) can be set up for up to 10,000 seconds. | | Independent Up and Down Speeds | AF016 | Configurable speeds for up and down 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. | | Load Holding | 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 | Includes all functions listed above, plus 09-1214 interface cable and 09-1158 USB cable. Requires a Series 7 or 5 gauge or indicator with load cell. |
