Overview
Constructed from high-strength glass-reinforced Polyphenylene Sulfide (PPS) thermoplastic, the housing resists corrosion and maintains structural integrity under industrial conditions. Furthermore, stainless steel sleeves, retaining chains, and exterior screws provide added durability. Therefore, engineers can rely on this assembly for turbines, compressors, and other rotating machinery, even when exposed to harsh environmental conditions.
Designed to comply with API 670 standards, this housing assembly supports intrinsically safe installations when paired with approved transducer systems and I.S. barriers. In addition, its CSA and IP66/NEMA 4X certifications confirm suitability for hazardous and wet environments. Consequently, the 31000 series combines reliability, precision, and ease of maintenance for industrial vibration monitoring applications.
