Auto Sensor Measure Brake Pedal Effort, Preamps Operate Up to 120 C

March 12th, 2008

PCB Piezotronics’ new series of pedal effort load cells are aimed at automotive test applications, including brake development, drivability, vehicle handling, and legislative & safety testing. Designed to measure the force required to operate a vehicle’s primary brake, clutch, or floor-mounted emergency brake pedals, the Series 1515 brake pedal effort sensor with integral cable is compact, with a 1.19” (3.02 cm) overall height. It is designed to be easy to install and remove, and is temperature-compensated for +30 to +130 °F (-1 to +54 °C).

The brake pedal effort sensor is designed with high overload protection (500% of FS), and an integral loading surface that rejects off-axis loading errors. These sensors are offered in a broad range of capacities, and provide good resolution, linearity, and repeatability in both static (constant force) and dynamic (panic stop) loading events.

PCB’s new high-temperature preamplifier is designed to overcome high temperature testing challenges associated with NVH powertrain and vehicle underhood testing applications, and to broaden options for NVH test engineers collecting acoustic data in high temperature areas. Model HT426E01 is a 1/2” preamplifier operating from ICP sensor power, terminating with a BNC connector and utilizing standard coaxial cables. The model also features a low attenuation factor (-0.06 dB) and low noise characteristics, 4.9 µV, based on an A-weight scale.
