Specification :

The Lloyd Instruments' FTPlus coefficient of friction tester accurately measures static and kinetic coefficient of friction. These values are of importance in a wide range of industries including blown film, plastic sheet, paper, packaging and coating manufacture.

The FTPlus is a stand alone friction tester conforming to the requirements of ASTM D1894, ISO 8295 and TAPPI T549. The tester is supplied with these three standards pre-programmed, with a total of ten set-ups available for custom configuration.

A wide range of load cells are available in addition to one optional load cell that is supplied with the machine. A friction table is mounted directly on the tester, with a full set of accessories to achieve the ASTM, ISO and TAPPI requirements.

User configurable test screens allow for final movement limits, calculation limits (relative and absolute), sled weights and dimensions.

A high-resolution encoder is used to measure the sample extension and also to provide high accuracy speed control. The crosshead is driven by a high precision servo-motor and DC servo system to achieve a wide range of speeds throughout the full load range.

The machine is microprocessor controlled and is operated from the integral control console, which enables tests to be quickly and easily set up and performed. Large, positive feedback membrane switches with tactile and audible feedback enables test parameters to be established in conjunction with the backlit 4 line liquid crystal alpha-numeric display.

The machine may be programmed to perform up to 10 different tests and the statistics for each type of test are automatically calculated including static coefficient of friction, kinetic coefficient of friction, peak load and average load. Up to 600 samples can be stored in any of the test set-ups.

The FTPlus is a fully self-contained instrument, however an RS232 is provided to allow computer control using Lloyd Instruments NEXYGENPlus material test and data analysis software if required. The FTPlus may also be configured as a universal testing machine to perform tensile, compression, flexural and other mechanical tests up to 1 kN (225 lbf) with the appropriate grips and fixtures.
