The 144-201-000 stands out as a premium industrial vibration sensor within the renowned Vibro-Meter product line. Specifically, this CA 201 model provides high sensitivity and a wide frequency response to ensure accurate data collection. Because the device features a hermetically welded austenitic stainless-steel case, it maintains exceptional durability against corrosion and humidity. Furthermore, the internal case insulation effectively prevents ground loops and electrical interference during sensitive measurements.
Meanwhile, this piezoelectric device operates efficiently across a broad temperature spectrum, making it ideal for monitoring rotating machinery in power plants. Additionally, the symmetrical sensor design utilizes a differential output to enhance signal-to-noise ratios in electrically noisy environments. Specifically, the integral cable and protective hose assembly provide a leaktight seal that resists steam and oil contaminants. Therefore, engineers frequently choose this specific model for critical monitoring tasks in refineries and gas turbines.
The core of the 144-201-000 lies in its impressive measurement capabilities and robust electrical characteristics. First, the unit delivers a nominal sensitivity of 100 pC/g, which allows for the detection of even minor mechanical imbalances. Additionally, the dynamic measurement range extends from 0.01 to 400 g peak, accommodating both steady-state and transient vibration levels. Specifically, the frequency response spans from 0.5 to 6000 Hz, ensuring comprehensive coverage of most machinery fault frequencies.
Furthermore, the internal insulation resistance exceeds 109 Ω, which guarantees minimal signal loss during long-distance transmission. Besides the primary sensor capacitance of 5000 pF, the integral cable adds a specific capacitance of 105 pF per meter. For instance, the CA 201 unit maintains excellent linearity within 1% for standard dynamic ranges. Finally, the resonant frequency of the device is greater than 22 kHz, preventing interference with low-frequency monitoring signals.
Regarding physical construction, this accelerometer utilizes high-grade austenitic stainless steel (1.4441) for its housing. Specifically, the flexible protection hose is crafted from heat-resistant stainless steel to ensure longevity in harsh conditions. Meanwhile, the 144-201-000 can withstand a continuous operating temperature range from −55 to +260°C. In addition, the assembly remains impervious to 100% relative humidity, salt spray, and various industrial chemicals.
Specifically, the CA 201 model features an integral cable that survives short-term exposure up to 250°C. Moreover, the unit demonstrates high shock resistance, tolerating accelerations up to 1000 g peak without damage. Therefore, it remains functional even during sudden mechanical impacts or extreme structural stress. Furthermore, the base-strain sensitivity is remarkably low, ensuring that mounting surface deformations do not compromise the accuracy of your vibration data.
Proper mounting of the CA 201 is essential for achieving the rated frequency response and data accuracy. First, prepare a flat, clean surface on the machinery housing to ensure optimal contact with the sensor base. Next, use four M6 x 35 Allen screws to secure the 144-201-000 to the target equipment. Specifically, you should apply a nominal tightening torque of 15 Nm to achieve the required structural rigidity.
Additionally, the sensor does not require electrical insulation of the mounting surface due to its internal case isolation. Furthermore, you must connect the flying leads of the integral cable to a compatible charge converter, such as the IPC70x signal conditioner. Meanwhile, ensure the protective hose is routed away from sharp edges to prevent mechanical wear over time. Finally, verify the wiring polarity to maintain the integrity of the differential signal output.
