Piezoelectric Accelerometer

Description

San Juan Capistrano, CA: Model 2010A piezoelectric accelerometer, with integral electronics (IEPE) provides general vibration measurements on structures and objects. It features a high signal-to-noise ratio, high output sensitivity, and a wide bandwidth up to 10 kHz. Low impedance voltage output is transmitted through the same cable that supplies the constant current power. VIP Sensors
