The Endevco® Model 2222D
Product catalog summary
Overview: The Endevco Model 2222D is a miniature piezoelectric accelerometer designed for vibration measurement on small structures. It is renowned for its lightweight design (1 gm) which minimizes mass loading, and it operates without the need for an external power source.
Features: The accelerometer uses Endevco's Piezite Type P-8 crystal element in annular shear mode, ensuring stable output sensitivity over time. It includes a hard-anodized mounting adapter for ground isolation and a low-noise coaxial cable for reliable operation. Removal tools are provided for field use.
Specifications: The Model 2222D conforms to ISA-RP-37.2 (1964) standards. Key specifications include a charge sensitivity of 1.1 pC/g (typical), a resonance frequency of 45 kHz, and an amplitude response range of 3 to 10,000 Hz (±5%). It operates effectively within a temperature range of -67°F to +347°F and is hermetically sealed for humidity resistance.
Electrical Characteristics: The accelerometer has an output polarity where acceleration directed into the base produces a positive output. It features a resistance of ≥10 GΩ and a capacitance of 120 pF.
Environmental and Physical Characteristics: The device can withstand sinusoidal vibrations up to 1000 g pk and shock limits up to 10,000 g pk. It is constructed from titanium alloy and uses adhesive mounting.
Calibration and Accessories: Calibration data traceable to NIST is provided. Accessories include a removal tool, cable assembly, ground isolation mount, and optional items like an adhesive mounting kit and triaxial mounting block.
Recommendations: For optimal performance, use with Endevco signal conditioner models 133, 2775B, or Oasis 2000. Proper cable management is crucial to prevent failure during high g and large displacement scenarios.
Notes: The document emphasizes the importance of using appropriate adhesives for mounting and recommends Endevco's factory calibration services for maintaining precision.
