Dynamometer Facility

JE have top quality dynamometer facilities combined with the expertise and staff to maximise this resource. We can carry out a full range of work from simple data logging to advanced project development. Please contact us to discuss your requirements. Commercial and intellectual integrity is, of course, guaranteed.

Dynamometer cells
Currently there are 2 fully computer controlled cells,
And 2 manually operated cells (very quickly upgraded if needed).

Specification of the two cells are as follows:

Cell 1: Froude FO201 hydraulic, 600kW, 1235Nm, 10,000rpm.
Cell 2: Schenk W230 eddy current dynamometer, 250kW, 600Nm, 8,000rpm.

Cell dimensions: 4260mm long, 4500mm wide, 2680mm high.

Control System:
CP Cadet 12 with fully programmable automatic control of dyno speed, throttle and safety backup systems. Programmable test cycles (999 stages per cycle) and self monitoring allowing 24 hour running.

8 Channel engine protection system.
16 bit monitoring of; torque, throttle, speed, fuel flow, 24 thermocouples, 8 PRTS, 10 pressure, 8 voltages, and 16 digital inputs.
