Standard models are available for front wheel, rear wheel, and all wheel drive vehicles. Applications include characterisation of road load driving conditions and coastdown, emissions correlation, braking and chassis dynamometer tests.
Installation is made without vehicle rework. Mounting the torquemeter on a standard wheel produces a small offset. The offset can be eliminated with a modified wheel. Torquemeter weight and inertia emulate a conventional wheel.
Excellent temperature compensation and a unique sensor design provide intrinsic immunity to temperature gradients and radial and cornering loads. These torque wheels are constructed of corrosion resistant materials and waterproofed to permit operation in shallow water. They also exhibit unprecedented tolerance to inevitable cable shunts caused by salt or other contaminants.
These models require strain gage, AC carrier style amplifier with capable of providing 3 - 6 volts rms at 3 kHz ±10%.
