Precision Filters, the leader in signal conditioning technology, designs and produces products used around the world for automotive test applications including testing engines and powertrains, aerodynamics in wind tunnels, NVH, wheel balance, and more.
With the need for test engineers to better understand conditioning strain, pressure and vibration sensors operating in high temperatures, sometimes exceeding 500°C, PFI just released Signal Conditioning for Exhaust System Measurements, a comprehensive technical note discussing the problems and solutions of testing in harsh conditions.
For additional reading on measuring strain, pressure, and vibration under the harshest conditions please visit our Automotive Testing Solutions webpage.
Precision Filters’ range of products support any installation, large or small, including in-vehicle, test-cell, and lab environments.
28000 Signal Conditioning System
Ideal for test cell applications, our versatile 28000 system features a built-in NIST traceable self-test for performing annual calibrations and automated pre-test go/no-go tests for run-time system verification. The 28000 includes a complete line of signal conditioners suitable for dynamic or static measurements and able to accommodate any transducer: voltage, charge, static, or dynamic strain, as well as bridge-type transducers such as pressure sensors, piezoresistive accelerometers, load cells, and more.
C Series Signal Conditioning Modules
When you need a rugged, portable system, our high-performance C Series signal conditioning modules integrate seamlessly with National Instruments’ CompactRIO™ and CompactDAQ™ chassis, making them ideal for in-vehicle installations or installations close to the DUT.
For low channel count labs, choose the economical two-channel PFA-2 filter/amplifier or the eight- or sixteen-channel PF-1U-FA filter/amplifier. Both are compact, highly programmable, and offer flat/pulse low-pass filter technology for time- or frequency-domain measurements.
