The PX831 is a durable, accurate, fixed range transmitter designed to give years of stable performance in even the toughest environmental and media conditions. The small size and lightweight of the PX831 eliminates the need for complicated mounting hardware and mechanical supports, thereby reducing installation time substantially. The in-line connection permits simple field wiring without the need for additional hardware, adding to the speed and ease of installation. With its all welded design, the PX831 is weatherproof and capable of withstanding a direct spray with forces up to 200 psi without internal leakage. All 316 stainless steel housing and wetted parts make it compatible with corrosive media and hazardous environments. The PX831 is designed to meet FM explosion-proof ratings and NACE standards for offshore requirements.
