Pressure transmitter

Relative pressure transmitter
Type 525

The pressure transmitter type 525 has a compact and robust
design and a very high measurement accuracy.
The pressure transmitter with it’s large variety of pressure andelectrical connection has also pressure ranges from 50 mbar
full scale.
The compact 525 pressure transmitter is based upon the wellproven ceramic technology developed by Huba Control over
20 years ago.
