0911472255The Nivovent 77-XP Series Combined Level & Temperature Switch with Breather Filter is engineered and manufactured by Bühler Technologies GmbH – a leading German technology company globally recognized for advanced fluid control solutions and hydraulic reservoir automation. The Nivovent 77-XP series introduces a breakthrough "All-in-One" design that integrates three essential functions into a single tank mounting port: liquid level monitoring, hydraulic oil temperature control, and air breather filtration.
In traditional hydraulic power unit designs, drilling multiple mounting ports on reservoir lids to individually fit breather caps, float switches, and temperature sensors increases machining costs, introduces potential oil leak paths, and consumes valuable tank top surface area. The Bühler Nivovent 77-XP resolves these engineering challenges through its ultra-compact unified housing, significantly simplifying assembly workflows, reducing bill-of-material costs, and optimizing reservoir space.
Key technical highlights of the Bühler Technologies Nivovent 77-XP:
- Precision Multi-Parameter Monitoring System: Equipped with a sensor stem housing a magnetic float for min/max fluid level detection, alongside integrated temperature sensors (PT100 or bimetallic switches) to deliver immediate alerts for oil level drops or thermal overheating.
- High-Efficiency Integrated Air Breather: Features a top-mounted breather filter assembly with high-quality filter elements (3 µm - 10 µm rating) that purifies air entering and exiting the reservoir during cylinder actuation, effectively preventing fine particulate dust and atmospheric moisture from contaminating hydraulic oil.
- Heavy-Duty Industrial Materials: Sensor stems and floats are crafted from 316L Stainless Steel or premium Brass, while breather housings are constructed from UV-resistant and high-temperature engineering polymers, guaranteeing reliable performance in harsh environments.
- Modular & Flexible Configuration: The 77-XP series supports multiple stem lengths, customizable switching contact points (1 to 4 limit switches), various output signal formats (Analog 4-20mA / IO-Link / Potential-free contacts), and optional visual level sight glasses.
The Bühler Nivovent 77-XP combined sensor is the ideal choice for hydraulic power packs in plastic injection molding machines, steel rolling mills, CNC machine tools, cement plants, thermal power stations, metallurgical facilities, and heavy industrial lubrication systems.
