The rear of the crosshead is attached to a vertical linear rail assembly that accurately defines
the crosshead alignment. This system ensures minimal sideways movement of the crosshead
together with minimal vertical "rocking" of the crosshead under all loading conditions.

LS machines are bench mounted, microprocessor controlled, single column loading
frames. The high stiffness frame incorporates a crosshead guidance system to prevent side
loading of the sample under test. The crosshead is driven by single leadscrew, motor and DC
pulse width modulated system to achieve a wide speed range over the full load range.
These machines are capable of running full load at full speed
The basic 1KN Model (LS1), shown at left can run simple tests without software.  However, using Nexygen Plus Software greatly enhances test capabililty, reduces human error and enables conformance to many industry standard tests (ASTM, BIN, etc.).  The table below gives the force range, speed and maximum travel of the LS1, LS2.5 and LS5 machines:

Load cells are easily changed for light duty testing.  Electronics in the load cell connectors retain the Load Cell information (size, calibration points & serial number) along with history of overloads.  To change, turn off power to the machine. Next, simply disconnect the Load Cell's electircal connectcion and loosen a single bolt to remove.  Install another load cell in it's place (electrical connector and bolt connection is the same for all load cells). 

Load cells for lower range testing are recommended according to need.  The following table shows available load cell sizes for the LS series machines.  Note, we recommend keeping back up load cells in case one is accidently damaged or overloaded.

Important notes on POGO configured machines:  The LD and LS Series machines can be configured for POGO testing.  Please indicate when ordering if a POGO conversion is required and we will be happy to help with application.  We sell lower frames with Powder Coating or Paint.  The machine is bolted to the lower frame. POGO conversions can be for Tension or Compression testing.  We also make Splinter & Safety Sheilds with electronic interface.  Click here for Grips & Accessories.

FT1 Friction Tester
Special LS1 with Friction Table
Coefficient of Friction, static and kinetic, is used in a variety of materials from lubricants, to films to household items (ceramic tiles) to determine the frictional characteristics of a material.

The FT1 is a bench mounted, single lead screw dedicated friction tester. A friction table is mounted directly on the machine, with a full set of accessories included to perform tests conforming to the requirements of ASTM D1894, ISO 8295 and TAPPI T549. The tester includes these standards as user configurable tests, with a further seven available for user custom configuration. User configurable test screens allow for final movement limits, calculation limits (relative and absolute), sled weights and dimensions.

Works with or without a Computer!  Computer advantages are many (Contact Us for details)

Note:  This system provides Static and Kinetic Coefficients even when used in stand-alone mode (without a computer).  However, adding Nexygen Plus software greatly expands test capability.  Add Nexygen Software for networking, advanced automation and much more.  Contact Us for expert application assistance.
