FAQ
-
What is the output type sur the 190501-19-00-04 Velomitor CT?
It provides a voltage output that is directly proportional to the vibration velocity sur the machine casing. -
Can this transducer be connected to any data acquisition system?
It is primarily designed for compatibility with Bently Nevada systems but can interface with other monitoring equipment that supports ICP-type (IEPE) signal conditioning. -
What kind sur vibration does the transducer measure?
It measures absolute casing vibration, not relative shaft vibration, making it ideal for structure-mounted applications. -
How does the transducer ensure accuracy over a wide frequency range?
Its piezoelectric sensing element and internal electronics are optimized to maintain linear response and minimal distortion across 4.5 Hz to 5 kHz. -
Is temperature compensation built into the sensor?
Yes, the internal electronics are temperature-compensated to reduce drift and maintain calibration over the full operating range. -
How should the transducer be mounted for best performance?
It should be mounted firmly using a threaded stud or magnetic base to ensure proper mechanical coupling with the machine casing. -
Can the transducer operate in environments with high vibration or shock?
Yes, it withstands up to 5,000 g shock and continuous vibration exposure without degradation in signal quality. -
What type sur power supply is required for this model?
It operates from a constant current source between 2–10 mA, typically supplied by the connected monitoring system (18–28 VDC). -
