Pressure transmitter

Relative pressure transmitter
Type 526

The compact type 526 pressure transmitter is based upon thewell proven ceramic technology developed by Huba Control
over 20 years ago.
The pressure transmitter with it’s large variety of pressure- andelectrical connection has also pressure ranges from 100 mbar
full scale. These units are available in high quantities for OEM
customers with an excellent price to performance ratio.
