Detailed Introduction
1. Core Identity & Purpose
The CA202 144‑202‑000‑205 is a rugged piezoelectric accelerometer from Vibro‑Meter (Meggitt Sensing Systems), designed for continuous vibration monitoring in heavy‑duty industrial applications. It delivers reliable charge‑mode output for precision measurement of dynamic forces in turbines, compressors, and rotating machinery, supporting predictive maintenance and machinery health management while withstanding extreme temperatures and mechanical stresscatalogue.meggittsensing.com.

2. Key Hardware & Performance
Sensing Element: Symmetrical shear‑mode polycrystalline piezoelectric element with internal case insulation and differential output for stable, low‑noise charge signalscatalogue.meggittsensing.com.
Output & Sensitivity: 2‑wire charge output, 100 pC/g (±5% tolerance), requiring an external charge amplifier (e.g., IPC704) for voltage/current signal conversion.
Frequency Response: ±5% from 0.5 Hz to 5,000 Hz; mounted resonant frequency 20 kHz nominal, enabling broad‑bandwidth vibration capture.
Dynamic Range: 0.01 g to 400 g peak (random), 500 g peak overload capacity; linearity ±1% (0.01–20 g), ±2% (20–400 g).
Mechanical Design: Austenitic stainless‑steel housing, hermetically welded with 3m integral low‑noise cable (135 g/m) and flexible stainless‑steel protection hose for leak‑tightnesscatalogue.meggittsensing.com.
Mounting: Four M6×35 Allen screws with M4 spring‑lock washers; 15 Nm torque; no electrical insulation needed for mounting surface.
Weight: Accelerometer 250 g nominal; cable 135 g/m.

3. Environmental & Operational Ratings
Temperature: Operating -55°C to 260°C; storage -55°C to 260°Ccatalogue.meggittsensing.com.
Insulation: Internal insulation resistance ≥10⁹ Ω for long‑term stability.
Transverse Sensitivity: ≤3% for minimal cross‑axis interference.
Version: Standard (non‑Ex) with 3m cable; Ex‑certified variants available separately.
4. Integration & Usage
Signal Conditioning: Requires external charge amplifier to convert charge output to usable voltage/current for PLC/DCS integration.
Accessories: Compatible with JB105/JB106 junction boxes and MA133 thermal insulation kits for extended installation flexibility.
