CA202 144-202-000-116

CA202 144-202-000-116 is a piezoelectric accelerometer. The suffix “116” in the model number corresponds to the “Ex explosion-proof version with 6-meter integral cable” entry in the ordering table. This means the sensor carries Ex ia intrinsically safe certification and is supplied as standard with a 6-meter-long, integral, low-noise cable, allowing it to be used directly for vibration monitoring of rotating machinery in potentially explosive gas atmospheres.

The sensor employs a symmetrical shear-mode polycrystalline measuring element, features internal housing insulation, and outputs a differential signal. Encased in an austenitic stainless steel housing, it offers a robust overall structure and strong resistance to interference.

The housing and the flexible stainless steel sheath are sealed together via welded joints to form a fully enclosed, leak-tight assembly capable of withstanding exposure to moisture, water, steam, oil, and seawater, as well as contaminants such as dust, mold, and sand particles.

• Sensitivity: 100 pC/g ±5% (at 120 Hz and 5 g)
• Output: 2-pin system, isolated from the housing, charge output
• Signal Processing: Requires a charge-to-voltage converter, such as the IPC70x signal conditioner
• Power Requirements: The sensor itself does not require an input power supply
• Cable: 6 m integral cable with flying leads at the end
• Explosion-proof Version: Ex version, suitable for use in potentially explosive atmospheres
• High Sensitivity: 100 pC/g
• Frequency Response: 0.5 to 6000 Hz
• Wide Operating Temperature Range: Sensor can operate up to +260°C
• Version Options: Available in standard and Ex versions; the Ex version is suitable for use in potentially explosive atmospheres

At a petrochemical plant’s reaction/compression unit, the facility area is classified as a Zone 1/Zone 2 hazardous area. The 144-202-000-116 intrinsically safe sensor (with a 6-meter integrated cable) was selected to monitor bearing housing vibration.

The 6-meter cable can be routed directly to a nearby junction box in a safe area, eliminating the need for on-site wiring and reducing the complexity of explosion-proof wiring. It provides stable output over the long term in high-temperature, oil- and gas-laden environments, supporting the detection of unit imbalance, misalignment, and early-stage bearing defects.
