(Alpha LFW-1)
ASTM Specifications :   D-2509, D-2714, D-2782, D-2981, D-3704, G-77
 
Features and specifications
 
Speed and Velocity:
Ten turn variable speed control potentiometer with digital display. Dual speed range from 25 to 900 rpm and 100 to 3600 rpm. Optional ranges from 0.5 to 25, 10 to 600 and 150 to 7200 rpm. All speeds ± 0.5% accuracy*. Linear speed at 7200 rpm: Falex Test Ring - 2536 fpm; Timken test Ring - 3652 fpm.
 
Load:
Applied through 10:1 lever system with dead weights. Bale rod weights supplied from ¼ lb to 80¾ lb. total. Optional extra weights for 130 lbs. Maximum bale load. Optional pneumatic system available using microprocessor control. Optional Microprocessor Data Acquisition and Control System test loads from 50 to 1300 lbs. ± 2% accuracy* using a pneumatic system. With low load option from 10 to 100 lbs. ±2% accuracy*. Optional Dual Load Range Electronic Calibration Device is available to field calibrate.
 
Temperature Control:
Controlled system with digital proportional controller/indicator, heaters, and automatic temperature start-up. Test area environment temperatures: standard machine to 204°C (400°F), maximum, with pressure chamber option to 250°C (480°F).
 
Environments:
Wet or dry. Standard machine has chamber cover for containing test fluids. Pressure chamber option allows pressurisation of chamber to 150 psig and vacuum testing. Optional lubricant recirculation system available. Optional grease feeding attachment for rotational or oscillatory tests.
 
Motion:
Unidirectional or optional oscillatory, both high and low speed.
Low speed from 20 to 600 cycles per minute, 0° - 90°.

* All accuracies are percent of full scale. Equipment can be designed with other specific accuracies if required and are available on special request.
 
Wear:
Continuous display dial indicator. Allows rate of wear and total wear measurement. Each division .0001". An optional electronic wear measuring system is available.
 
Friction Force:
Load cell with a digital panel mounted indicator and digital thermal printer. Automatic friction force cut-off. Built-in field calibration system. Optional low range for greater accuracy in measuring torque from 0 to 25 lb?in, ±2% accuracy.
 
Specimen Temperature:
Panel mounted digital indicator and digital thermal printer. Adjustable automatic temperature limit cut-off. Thermocouple included.
 
Test Time:  Digital timer/controller for automatic start-up or shut-off.
 
Motor:  2 HP, variable speed DC motor.
