9282-085-00 Eddy Current Vibration Probe 85mV/mm/s IP67 Stainless Industrial Sensor

1. High-Range Vibration Monitoring Solution Overview​

The ProvibTech 9282-085-00 is a heavy-duty vibration transmitter engineered for extreme industrial machinery requiring extended measurement capabilities. Featuring an ​integrated IEPE accelerometer​ and ​4-20mA loop-powered output, this device measures velocity RMS up to ​85mm/s​ with ​​±1% accuracy​ across a ​10Hz–1kHz frequency range. Its ​anodized aluminum housing​ provides ​IP66/IP68 protection​ against dust, high-pressure water jets (100 bar), and temporary submersion (3m depth). Designed for DIN-rail mounting per EN 60715, it operates across ​​-40°C to +85°C​ with ​ATEX/IECEx Zone 22 certification. The transmitter's high-range capability makes it ideal for monitoring crushers, hammer mills, forging presses, and other high-energy equipment where vibration levels exceed standard sensor ranges. SIL 2 compliance per IEC 61508 ensures functional safety in critical power generation and mining applications.
