Open Water Propeller Dynamometers

Product Description

Open Water Propeller DynamometersThe propeller dynamometers are new designs to replace earlier dynamometers only adjustments to the inclination of the propeller shaft could be made, but with the introduction of the adjustment of propeller shaft height can also be achieved.Apart from the different arrangement possibilities,the technical details of all essential parts of propeller dynamometers are identical, with exception of the capacity of the drive motors and the maximum load ratings in respect of measurement of torque and thrust. The capacity of the drive motors of the same whereas that of less. Depending on the maximum capacity of the drive motors, the maximum torque ratings, and consequently the diameters of the propeller shaft ends, are different.Technical Data of Open Water Propeller Dynamometers: Rated torque, up to: 100 NmRated thrust, up to: 2 kNLoad sensor for torque and thrust measurement Full bridge strain gauge type transducerPermitted overload of the transducers for a short moment inclusive dynamic peak: 25%Temperature compensation: For feeding with constant voltage (not constant current)Input resistance: Approx. 257Output resistance: Approx. 240Recommended supply voltage up to: 10 V DC or ACMaximum supply voltage: 15 V DC or ACOutput voltage at rated load referred to the feeding voltage Approx. 16 mV/VDrive motor: 32 kW at 3000rpmDiameter of propeller shaft end (for taking up the boring in the boss of the propeller to be tested: 22mmRated torque upto: 150 NmRated thrust, up to: 3 kNLoad sensor for torque and thrust measurement Full bridge strain gauge type transducerPermitted overload of the transducers for a short moment inclusive dynamic peak: 25%Temperature compensation For feeding with constant voltage (not constant current)Input resistance: Approx. 257Output resistance: Approx. 240Recommended supply voltage up to: 10 V DC or ACMaximum supply voltage: 15 V DC or ACOutput voltage at rated load referred to the feeding voltage Approx. 16 mV/VDrive motor: 64 kW at 4000 rpmDiameter of propeller shaft end (for taking up the boring in the boss of the propeller to be tested: 25mm
