EDDY
CURRENT DYNAMOMETERS
(PEC RANGE)
25 – 530 BHP / 58 – 1450 lb/ft.
The PEC range of dynamometers provide a range of Eddy –
Current machines designed for testing engines from 25 to 530 BHP.
Eddy current dynamometers are well known for their stability and
suitability to operate in a closed loop mode.
The
rugged design of the power absorbing unit ensures a long operating
life,even in the most demanding production and endurance testing
environments. This long life is further enhanced by the nickel
plating of critical components in contact with the water.
Speed is measured by a pulse sensor mounted adjacent to a 60
tooth wheel on the coupling while torque is measured by a high
accuracy strain gauge load cell mounted between the trunnion bearings,
supported casings and bedplate. Control is achieved by varying
the excitation current to the coils. When used in conjunction
with feed back signals for torque from the load cell and speed
sensor closed loop can be provided.
In addition to the PDD (Digital Dyno Drive) and the PETA (Engine
Throttle servo Actuator and drive), additional performance channels
can be monitored by integrating the Piper P9,
P10,
P11,
P12, P15,
P15EDA or
P15EDAC
instrumentation. These instruments are available with computer
interface and Piper display software.
Numerous options are available such as drive shafts, guards,
calibration systems, engine mounting frames, circulation pumps
and cooling towers. See our System accessories pages for additional
details.
