Industrial Accelerometer
Model 5220-HF
* * * * High Frequency Vibration Measurement API 670 Compatible Ground Isolated with Faraday Shielding Resonance Suppression Circuitry
ENDEVCO
MODEL 5220-HF
DESCRIPTION
The ENDEVCO(R) Model 5220-HF series accelerometer complies with the requirements of API 670 and is designed specifically for wide bandwidth vibration measurement in the rugged environments of industrial machinery monitoring. This accelerometer incorporates internal signal conditioning to provide a low impedance output. Model 5220-HF offers a very wide dynamic range and an extremely low noise floor. The Model 5220-HF incorporates an active 2-pole low-pass filter for resonance suppression. Signal ground is isolated from the mounting surface and outer case to prevent ground loops, and the sensor is hermetically sealed to ensure long-term operation with excellent stability. The Model 5220-HF incorporates faraday shielding to limit sensitivity to ESD to a minimum. The Model 5220-HF features ENDEVCO's PIEZITE(R) Type P-8 crystal element, operating in shear mode, in an electrically isolated sensor and charge amplifier unit. Model 5220-HF is provided with a 1/4-28 UNF mounting stud and M8 x 1.25-6g metric adaptor mounting stud. The following performance specifications conform to ISA-RP-37.2 (1-64) and are typical values, referenced at +24C (+75F), 24 Vdc supply, 4 mA constant current and 100 Hz, unless otherwise noted. Calibration data, traceable to National Institute of Standards and Technology (NIST), is supplied.
