750 – 2000 BHP/2400 – 7300lb/ft
The PB range of dynamometers are basic, robust, manual control
unit where cost is of prime consideration and simplicity of operation
is paramount. They are bi-directional which is achieved by rotating
the whole dynamometer to 180 degrees.
The PB range is not suitable for transient testing and the load
is controlled by varying the quantity of water circulating in
the vortex chamber. This is achieved by a moving sluice gate in
the dynamometer casing.
PB range is available with alternative control options:
1) Manual control for operation local to the dynamometer
2) Remote control via increase / decrease push buttons.
3) Throttle is controlled by push / pull cable arrangement.
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.
The Piper P9,
can be used with the PB range for data monitoring. 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.
