Roll Stability Tester
Standard Models – Roll stability apparatus for shear stability tests
on lubricating greases. Rotates steel test cylinders at 10 or 165rpm in a
thermostatically controlled environment at temperatures of up to 200°F
(93.3°C). Drive system is powered by a rugged ratio motor, and
interchangeable drive chain sprockets are easily accessible for converting
unit to either operating speed. Microprocessor PID control provides quick
temperature stabilization without overshoot and is protected by an
overtemperature control circuit that interrupts power should temperature
exceed a programmed cut-off point. Dual LED displays provide actual and
setpoint temperature values in °C/°F format. Communications software
(RS232, etc.), ramp-to-set and other enhanced features are available as extra
cost options. A balanced cast aluminum fan and 1200W heater provide
efficient, uniform heat distribution. A dial thermometer in the hinged cover
displays chamber temperature. Heaters and drive chain mechanism are shielded
for operator safety. Insulated steel cabinet and base are finished with a
durable polyurethane enamel finish.
High Temperature Models – A high temperature model is also available
that expands the temperature range to 320°F (160°C). Tests can be conducted
using the high temperature model unit for time/temperature specifications
beyond those listed in existing D1831.
