This piezoelectric device provides exceptional accuracy for industrial vibration measurement. The CA202 sensor utilizes a symmetrical shear-mode polycrystalline element to achieve a high sensitivity of 100 pC/g. Because the housing uses austenitic stainless steel, the unit withstands temperatures ranging from -55 to 260°C. Furthermore, the hermetically welded construction protects internal components from 100% humidity, steam, and oil.
Meanwhile, this specific model excels in hazardous areas and potentially explosive atmospheres. The 144-202-000-203 features a leaktight assembly with a flexible stainless-steel protection hose. This hose is hermetically welded to the sensor body to prevent contamination from dust or sea salt. Specifically, the internal case insulation and differential output minimize electrical noise. Therefore, engineers rely on this hardware for long-term monitoring of critical machinery.
The performance of this Vibro-Meter hardware depends on its wide dynamic range and linear response. The 144-202-000-203 measures vibration levels from 0.01 to 400 g peak, with an overload capacity reaching 500 g. The unit maintains a flat frequency response from 0.5 to 6000 Hz, making it suitable for low-frequency structural analysis. Additionally, a high resonant frequency above 22 kHz ensures signal purity during high-speed rotations.
The hardware includes an integral low-noise cable protected by a heat-resistant stainless-steel hose. Besides its core sensing role, the device exhibits minimal transverse sensitivity and low base-strain error. For instance, the sensor maintains high insulation resistance even at elevated operating temperatures. Finally, the robust 250g housing ensures stability when mounted using the standard four-bolt pattern.
Successful integration of this accelerometer requires a compatible charge converter or signal conditioner. The 144-202-000-203 typically pairs with the Vibro-Meter IPC70x series signal conditioner to convert charge signals into voltage or current. This CA202 version comes with flying leads for direct terminal connection in junction boxes. Moreover, the symmetrical two-pin system remains fully insulated from the case ground to prevent ground loops.
Specifically, the "203" variant denotes a specific configuration within the CA202 family, often tailored for unique cable lengths. Therefore, the 144-202-000-203 remains a foundational asset for power generation and chemical processing plants. Its passive design requires no external input power, simplifying the instrumentation architecture for remote monitoring points.
Successful deployment requires correct mounting torque and cable protection. First, secure the sensor using four M6 x 35 Allen screws with a nominal torque of 15 Nm. Next, route the flexible protection hose to avoid excessive mechanical stress or sharp bends. Specifically, you should ensure the mounting surface is clean and flat to maintain optimal frequency response.
Additionally, verify the insulation resistance of the 144-202-000-203 before connecting it to the IPC70x conditioner. You should also check the integrity of the hermetic welds on the protection hose in high-humidity zones. Meanwhile, monitor the differential output during machine startup to confirm a stable 100 pC/g sensitivity. Finally, ensure all flying lead connections are moisture-sealed to prevent signal degradation in harsh climates.
