Key Features and Engineering Advantages

• Comprehensive Triaxial Sensing: Captures vibration data in three axes (X, Y, and Z) simultaneously. This provides a complete 3D "picture" of machine health, allowing for the detection of complex faults like misalignment and imbalance that single-axis sensors might miss.

• Integrated Temperature Monitoring: Correlating vibration spikes with temperature changes is essential for identifying bearing failures. This dual-sensing capability reduces the number of required nodes per asset.

• ISA100 Wireless Connectivity: Utilizes the robust, mesh-capable ISA100 protocol, ensuring reliable data transmission even in environments with high metal density and electromagnetic interference.

• Hazardous Area Certified: Built to Class I, Division 1 standards, this sensor can be safely deployed in explosive atmospheres typical of oil refineries, gas processing plants, and chemical facilities.

• Extreme Long-Life Battery: With a lifespan of up to 5 years, this sensor significantly reduces maintenance overhead. The battery is easily replaceable, ensuring the sensor housing remains a long-term asset.
