Hydraulic dynamometer (10 inches)

The braking load of a hydraulic dynamometer is directly related to the amount of fluid entering the device, which is controlled through an inlet valve. The amount of force applied to the fluid raises the temperature of the cooling water. The maximum temperature of the output water from the dynamometer is 70°C. In essence, the dynamometer operates like a faulty water pump, exchanging the applied force with heated water.

Rotor speed is measured using an inductive sensor inside the dynamometer, and the required power is calculated by multiplying torque by speed. The characteristic curve of the dynamometer varies with speed and is detailed as follows. The device features a touchscreen display panel, which allows for data input as well as display and storage of information. Additionally, it is equipped with an oil pressure sensor and an exhaust temperature sensor.

The device can support additional data logging cards and displays, based on customer request. Data can also be recorded in the device’s internal memory or an external memory. This data can later be viewed and analyzed on a computer.
