Product Introduction
The Bently Nevada 70M303 Ranger Pro Wireless Condition Monitoring Vibration Sensor is a next-generation, high-performance wireless sensor engineered for continuous monitoring of machinery vibration and process health. As a member of the Ranger Pro Wireless family, the 70M303 offers enhanced sensing precision, improved wireless reliability, and expanded dynamic measurement capabilities compared to earlier versions such as the 70M300 and 70M301.
This sensor is specifically designed for industrial-grade asset condition monitoring, providing real-time vibration and temperature data through ISA100 or WirelessHART protocols. It eliminates the need for complex wiring infrastructure, reducing installation costs and enabling scalable deployment across multiple facilities.
Constructed with robust stainless steel housing and fully sealed to withstand oil, dust, and moisture, the 70M303 delivers exceptional performance in extreme industrial environments. It features high-resolution vibration data acquisition up to 10 kHz bandwidth, allowing early detection of bearing wear, imbalance, shaft misalignment, looseness, and other mechanical issues that may lead to unplanned shutdowns.
The 70M303 integrates seamlessly with Bently Nevada System 1† software, enabling centralized monitoring, trend visualization, and automated diagnostic alerts. Designed for both critical and non-critical assets, it supports proactive maintenance strategies that improve operational uptime, reliability, and safety.
