Himmelstein MCRT®环亚27000T Series Torque Wheels accurately measure wheel torque and speed during driving, braking and coastdown. Standard models are available for front wheel, rear wheel, and all wheel drive vehicles. Applications include characterization of road load driving conditions, and coastdown, emissions correlation, braking and chassis dynamometer tests.

环亚Installation is made without vehicle rework. Mounting the torque transducer on a standard wheel produces a small offset. The offset can be eliminated with a modified wheel. Torque transducer weight and inertia emulate a conventional wheel.

环亚Excellent temperature compensation and a unique sensor design provides 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.

环亚These models require strain gage, AC carrier style amplifier with capable of providing 3 - 6 volts rms at 3 kHz ±10%.
