Piezoelectric Sensor Signal Conditioner for Automotive and Aerospace Component
Depew, NY, USA – PCB Piezotronics, Inc. (PCB®) has introduced Model 482C54, a compact, full-featured, benchtop signal conditioner for ICP®, IEPE, and charge output piezoelectric sensors. The signal conditioner is compatible with accelerometers, microphones, pressure transducers, force sensors and strain sensors. Additionally, it can accept a direct voltage input signal, allowing it to be used with most voltage sensor signals. The unit has been designed for use in general purpose vibration testing, automotive and aerospace component testing, and HALT/HASS/ESS applications.
With no moving parts and solid-state construction, the durability of Series 175 is unsurpassed by any other type of pressure sensor. Frequency response may be adjusted for use during engine load changes on low or high-speed engines. These sensors have measurement ranges up to 3,600 psi (250 bar) and a maximum pressure of up to 4,000 psi (300 bar). They are well-suited for use in high temperatures up to +570 °F (+300 °C), and are packaged in stainless steel housings with rugged cables and connectors. Series 175 features a robust M14 thread, and may be mounted to existing engine pressure indicator valves.
Model 482C54 features four simultaneous operating channels, built-in charge converters, fine gain adjustment (x0.1 to x200 gain in 0.1 increments), fourth-order, 10k Hz low-pass Butterworth filtering (with other filter values optional), a low noise floor, and TEDS sensor support. The unit has a frequency range of 0.05 to 100k Hz, with a ± 10 V input voltage range and ± 100,000 pC input charge range.
User adjustments are accommodated via front panel keypad with menu-driven display, or an RS-232 computer interface. The unit also includes Windows® compatible control software, and is powered directly by DC voltage or by AC line power with an included universal AC power adaptor.
