Pressure transmitter 520
The compact Type 520 pressure transmitters are based on Huba Control’s advanced thick-film technology, featuring a hermetically welded, seal-free stainless steel measuring cell. They provide precise measurement of relative pressures up to 1000 bar and offer high burst pressure resistance, reliability, and long-term stability.
Type 520 pressure transmitters are suitable for use with liquids and gases, including all common refrigerants and ammonia. This makes them a reliable solution for a wide range of applications, from industrial processes or HVAC systems to railway components. Comprehensive approvals- including EMC with enhanced noise immunity, shock and vibration resistance, as well as certifications such as UL, EN 45545-2, ATEX and IECex confirm its suitability for diverse and safety-critical environments.
- Compact and robust stainless steel design
- Hermetically welded construction without seals, no risk of leaks
- High variety of connector options
- Time-saving, fast customer-side cable assembly with quick cable screw connection
- No elastomer seals
