BPFT: compact pedal force transducer, 2.2 kN
The BPFT is a precision strain gage load cell for the force on a pedal. Its rugged aluminum body is round, Ø 50.04 mm (1.97 in), and 48.26 mm (1.90 in) high. The capacity is 500 lbf (2.2 kN), with high accuracy for on-center and off-center loading. A four-arm bridge of 240 Ω gives an output of 2.25 mV/V nominal at up to 10 V DC or AC rms, with non-linearity of 0.1 % and hysteresis of 0.5 % of full scale. It is temperature compensated from 24 to 93 °C and usable from −40 to 149 °C, and is rated for more than 10⁶ cycles at full load on a single axis. It weighs 119 g and has a 3.05 m cable.
It was designed for the brake pedals of most cars and for parking brake pedals. A clamp holds the body on the pedal; the drawing gives its opening, 34.01 mm fully closed and 62.74 mm fully opened. Other clamping width ranges are available from the factory.
The BPFT is the compact, round model of the three pedal force transducers. The BPFT2, a low-profile plate of 113.03 × 50.8 mm, is for standard brake pedals, and the BPFT3, a plate of 69.0 × 56.3 mm, for smaller pedals.
