HYDRAULIC DYNAMOMETERS
FOR LOAD TESTING
PRIME MOVERS
Specializing exclusively in dynamometers and associated
equipment, Kahn introduced the flange trunnion mounted
hydraulic dynamometer over forty years ago. Since then,
significant advances have been continuously incorporated,
particularly in the areas of higher operating speeds and
increasingly sophisticated automatic controls. The result has
been a widely acknowledged leadership in product perform-
ance and reliability. Capable of delivering up to 80,000 hp
(60,000 kW) and operating at speeds up to 60,000 rpm,
Kahn dynamometers provide full power absorption in both
directions of rotation. Depending on individual test needs,
they are equipped with either manual or closed loop automat-
ic feedback controls and are available for a wide range of
applications. Kahn Model 109-200

■ AUTOMOTIVE
Kahn Series 301 hydraulic dynamometers for load-
testing automotive diesel and gasoline engines are now
available with a programmer for fully automatic control of
multi-step engine test cycles. Lightweight, flange trunnion
mounted design permits quick no-alignment-needed
installation directly on the engine flywheel housing. Tough
nickel-aluminum-bronze power elements insure superior
service life. Modular construction permits replacement of
the carbon face seal in less than an hour. Adapters are
available for popular engines. Four models with power
ratings from 400 hp (298 kW) to 1350 hp (1000 kW).
