The BENTLY 350045 excels in precision and adaptability, making it ideal for mission-critical applications. Its advanced signal conditioning delivers ±0.2% measurement accuracy, ensuring reliable detection of even subtle deviations from baseline conditions . The module’s wide operating temperature range (-40°C to +70°C) and IP65 rating safeguard against dust, moisture, and extreme environments, while electromagnetic compatibility (EMC) minimizes interference in high-noise settings like steel mills or petrochemical plants .

The BENTLY 350045 plays a pivotal role in industries where thermal expansion and axial movement pose significant risks. In oil refining, it monitors compressor casing expansion to prevent seal failure during start-up/shutdown cycles, ensuring compliance with API 617 standards. Similarly, in power generation, the module tracks turbine rotor axial position to avoid blade-to-stator contact, protecting multimillion-dollar assets from catastrophic damage .
