Detailed Description

The Bently Nevada 121M6466 (Ranger Pro Series) is engineered for precise monitoring of industrial rotating machinery. It captures vibration data in three axes and simultaneously measures machine casing temperature, enabling early detection of mechanical faults such as imbalance, misalignment, or bearing wear.

Using the ISA100.11a wireless protocol, the sensor transmits real-time data over distances up to 150 meters and supports secure encrypted communication. The long-life lithium-thionyl chloride battery minimizes maintenance requirements, lasting up to 5 years under typical operational conditions.

The robust housing, constructed from stainless steel and high-performance polymer, provides IP67 protection, making it suitable for harsh and hazardous industrial environments. The sensor operates across a wide temperature range and integrates with Bently Nevada System 1 for trend analysis, alarm management, and predictive maintenance, reducing downtime and improving overall equipment reliability.
