The Bruel-Kjaer VIBROCONTROL 868/1 is a robust and precise vibration monitoring device (Schwingungswächter) designed specifically for horizontal measurement applications. With its +24 V DC power supply and high reliability, it serves as an essential component for condition monitoring and predictive maintenance in industrial environments.
Engineered for accuracy and durability, the provides continuous real-time monitoring of vibration levels, enabling operators to detect early signs of mechanical problems such as misalignment, imbalance, and bearing wear. This early detection helps prevent costly unplanned shutdowns and extends the operational lifespan of critical machinery.
The device’s compact yet durable design makes it suitable for installations in challenging environments where space is limited but performance demands are high. It integrates seamlessly into existing monitoring systems, offering reliable relay outputs for alarms and control functions. The horizontal measurement orientation is particularly suitable for machines such as pumps, motors, fans, and compressors, where lateral vibration levels are a key indicator of operational health.
With an easy-to-install design and compatibility with a range of industrial systems, the simplifies setup while delivering consistent and accurate results. The device’s order code is VC-868/1, and it comes with complete documentation to ensure proper installation and operation, including details on relay terminal connections.
Manufactured in Germany (country of origin: DE), this vibration monitoring unit reflects the high quality and engineering excellence associated with Bruel-Kjaer products. The material number is C103665.001, ensuring precise identification for procurement and spare parts management.
Key benefits of the Bruel-Kjaer VIBROCONTROL 868/1 include:
Reliable horizontal vibration monitoring
Robust design for industrial environments
+24 V DC power supply compatibility
Easy integration with alarm and control systems
German engineering for long-lasting performance
In summary, the Bruel-Kjaer VIBROCONTROL 868/1 is a high-performance vibration monitor built to meet the demands of modern industry. Whether used for continuous machine protection or integrated into a larger predictive maintenance program, it delivers accuracy, durability, and peace of mind for operators and maintenance teams.
Technical Overview
The Brüel & Kjær Vibro VIBROCONTROL 868 ("Schwingungswächter", German for vibration watchdog/monitor relay) is a compact, standalone vibration protection unit from the manufacturer’s legacy VIBROCONTROL 800 series. It is designed as a self-contained field-mountable monitor for continuous casing/bearing-housing vibration surveillance on general rotating machinery, rather than as a rack-based module in a larger monitoring system such as VC-6000. Per Brüel & Kjær Vibro’s own catalogue documentation for the VIBROCONTROL 800 series, this horizontal-direction variant measures vibration velocity across a range of 0–50 mm/s and vibration displacement/amplitude across 0–500 µm, covering machinery operating speeds from 480 to 60,000 rpm.
The unit provides a single high-value (HV) alarm relay with one switching contact, with the alarm limit user-selectable from 0 to 100% of the measurement range and a response time delay selectable at either 1 or 5 seconds — a simple, robust configuration well suited to straightforward overall-vibration trip protection where a full multi-channel monitoring system is not required. Power supply is flexible, accepting 230V AC, 115V AC, or +24V DC depending on the installation’s available supply. The enclosure is a heavy-duty coated cast-aluminium housing rated IP65 for dust and water ingress protection, weighing approximately 1.6 kg, suitable for direct field mounting near the monitored machine without an additional protective cabinet. Seven Star LLC notes that while the base VIBROCONTROL 868 model and its horizontal-direction configuration are confirmed from official B&K Vibro documentation, the exact scope of the "/1" suffix on this specific part number was not independently confirmed from a directly accessible ordering table; customers should confirm this detail against their existing unit’s nameplate or with Seven Star LLC before ordering a replacement.
Applications
This class of compact vibration monitor is used on general industrial rotating machinery — blowers, fans, mills, and centrifuges — where a simple, reliable overall-vibration trip relay is needed to protect the machine from developing bearing or imbalance faults, without the cost or complexity of a full rack-based protection system. It is commonly retrofitted onto older machine trains that were not originally specified with modern multi-channel monitoring.
Why Seven Star LLC
Brüel & Kjær Vibro has since introduced the VIBROCONTROL 950/960 series as its current-generation compact monitor family, occupying the same market position as the legacy VC 800 series. Seven Star LLC helps customers across Oman and the GCC determine whether sourcing a genuine legacy VC 868 replacement or migrating to the current VC 950/960 platform is the better long-term choice for their installation, and supplies genuine Brüel & Kjær Vibro hardware with full documentation either way.
Request a Quote for Bruel-Kjaer -VIBROCONTROL 868/1 SCHWINGUNGSWÄCHTER
Contact Seven Star LLC to request a quotation for the Brüel & Kjær Vibro VIBROCONTROL 868/1 compact vibration monitor, or to discuss migrating to the current-generation VIBROCONTROL 950/960 platform. Our engineers support product identification, ordering-code verification, and reliable delivery across Oman and the wider GCC region.
Ordering Notes
When requesting a replacement quotation, please confirm the exact power supply option (230V AC, 115V AC, or 24V DC) and the mounting orientation of your existing unit, since these details, along with the precise "/1" suffix on your nameplate, allow Seven Star LLC to cross-check the correct configuration against Brüel & Kjær Vibro’s records before shipment.
Reliability and Field Service
Seven Star LLC also assists customers with sourcing recalibration services and spare relay/coil components for older VIBROCONTROL 800-series units still operating in the field, since many plants across Oman and the GCC continue to run this legacy hardware reliably on non-critical machinery. Our team can advise on realistic remaining service life expectations for aging cast-aluminium enclosure units operating in humid or coastal environments, and recommend an appropriate migration timeline where continued reliance on legacy hardware carries increasing risk.
