HUBA

400 Series Low Differential Pressure Transmitter

OEM Use, F.S. ranges 3 mbar (1.2” w.c.), 5 mbar (2.01” w.c.), 8 mbar (3.21” w.c.)

DESCRIPTION

The type 400 series pressure transmitters, with its unique proven ceramic fulcrum lever technology, has adjusted, temperature compensated sensor signals, available as a voltage output.

The (VDC) voltage output is an amplified, linear signal suitable for direct processing in electronic control systems.

They are for use with air and non-corrosive gases.

1. Pressure connection P1 (higher pressure)
2. Pressure connection P2 (lower pressure)
3. Electrical connection
4. Diaphragm
5. Ceramic fulcrum lever with amplified electronics
6. Over pressure stop
