Pressure transmitter 525
The pressure transmitters of Type 525 are characterized by their compact and robust design and very high measurement accuracy. In addition to a wide variety of pressure and electrical connections, pressure ranges starting from 50 mbar full scale value can be implemented.
The pressure transmitters are based on the ceramic technology developed by Huba Control, which has been successfully used millions of times for over 20 years.
- Very high measurement accuracy
- Excellent temperature behavior
- Low-pressure ranges possible from a full scale value of 50 mbar
- Compact and robust design
- Variety of pressure and electrical connection options
