Features
The pressure transmitters of Type 560 combine top performance with Swiss precision. The proven Huba Control stainless steel sensor technology is characterized by a hermetically welded design and high overpressure resistance. Since no seals are installed inside, the risk of internal leaks is eliminated. The 560 is ideally suited for demanding applications in refrigeration, hydraulics, compressed air, and other industries where reliability, long-term stability, and precision are crucial. The stainless steel technology enables the use of natural refrigerants such as R290, CO₂, and ammonia.
•Compact and robust stainless steel design
•Hermetically welded design without seals, no risk of leakage
•100 % inline helium leak test during production
•Compliant with DIN EN 60335-2-40
•Various configuration options
•Easy to install and maintenance-free
R290 Ready: This sensor is VDE Mark Approved according to EN IEC 60335-2-40 and designed for safe use in heat pumps with propane (R290) - observe application limits and media compatibility according to data sheet/certificate.
