In summary, the Bruel-Kjaer VS-069 is a dependable and precise stationary vibration velocity sensor that provides critical insights into machinery health. Its robust design, wide temperature range, protective cable features, and compatibility with industrial monitoring systems make it a valuable asset for any facility aiming to improve equipment reliability and operational efficiency.
Technical Overview
The Brüel & Kjær Vibro VS-069 is an electrodynamic (moving-coil) velocity sensor used for absolute vibration monitoring of machine casings and bearing housings. As a self-generating transducer, it requires no external excitation power — the internal moving coil generates a voltage directly proportional to vibration velocity as the machine casing moves relative to the sensor’s internal seismic mass. Per Brüel & Kjær Vibro’s official documentation for the VS-06x/07x velocity sensor family, the VS-069 has a standard frequency response of 10 Hz to 2000 Hz, with internal linearization extending usable sub-resonant measurement down to approximately 1 Hz, and a resonant frequency of approximately 8 Hz (±10%).
Sensitivity (transmission factor) is 100 mV/mm/s at 80 Hz (±5%), with an output impedance of 3.1–4 kΩ. Because the sensor is self-powered, its high-level analog output signal can be read directly by a monitoring system without a separate power supply or signal conditioning amplifier, simplifying installation on machines not already wired for powered proximity-probe systems. The VS-069 is specified for vertical mounting orientation via a central threaded bore (M10 or M8 depending on ordering configuration), and is housed in a stainless-steel casing rated from IP44 up to IP68 (5 bar) depending on the specific variant ordered, with an operating temperature range of −40°C to +80°C (short-term to +100°C). The standard VS-069 variant is not certified for hazardous-area installation; customers requiring ATEX/IECEx certification should confirm with Seven Star LLC whether a certified variant of the VS family is available for their application.
Applications
Electrodynamic velocity sensors like the VS-069 are widely used for absolute casing and bearing-housing vibration monitoring on turbines, pumps, motors, fans, and compressors across general industrial and process plant applications, where a simple, self-powered, reliable overall-vibration measurement is preferred over a powered accelerometer or eddy-current displacement system.
Why Seven Star LLC
Seven Star LLC supplies genuine Brüel & Kjær Vibro velocity sensors to customers across Oman and the GCC, and helps confirm the correct mounting configuration, cable/connector option, and IP rating variant for a given installation before ordering, ensuring compatibility with the customer’s existing monitoring system and mechanical mounting arrangement.
Request a Quote for Bruel-Kjaer -VS-069
Contact Seven Star LLC to request a quotation for the Brüel & Kjær Vibro VS-069 velocity sensor. Our engineering team can help confirm the correct mounting, cable, and IP-rating configuration for your specific machine, and support reliable delivery across Oman and the wider GCC region.
Ordering Notes
When requesting a quotation, please confirm the required mounting thread (M10 or M8), cable termination style (integrated cable or BNC connector), and any hazardous-area certification requirement, so Seven Star LLC can supply the correct VS-069 variant for your installation and machinery protection system.
Installation Considerations
Because the VS-069 is a self-generating sensor, cable length and routing should be considered carefully during installation, since excessive cable length or poor shielding can introduce noise into the low-level analog signal before it reaches the monitoring system’s input. Seven Star LLC recommends confirming the maximum supported cable run for your specific monitoring system input card, and using properly shielded, twisted-pair cable rated for the installation’s ambient temperature range, to preserve signal integrity for accurate absolute vibration measurement.
Genuine Parts Assurance
Sourcing a genuine Brüel & Kjær Vibro velocity sensor rather than a lower-cost unauthorized substitute matters for measurement accuracy and long-term reliability, since counterfeit or gray-market sensors can drift out of calibration or fail prematurely in harsh plant environments. Seven Star LLC’s authorized supply channel ensures every VS-069 sensor delivered to customers in Oman and the GCC is genuine, correctly calibrated, and backed by the manufacturer’s standard documentation.
