The Digital Transmitter DPH 400 is the latest generation of micro-controller-bas
ed vacuum gauges combining an ionization sensor after the Bayard-Alpert principle with a robust spiral coil filament Pirani to provide a full range pressure measurement from atmosphere to 5 ∙ 10-10 mbar.
Optional display version (DPH 400 D)
0 – 10 V signal and RS485 interface
Bayard-Alpert with double filaments for extended lifetime and high reliability
Automatic control of the ionization sensor
Bake-out up to 180°C without electronics removal
2 setpoint relays as standard
Plug and play sensor replacement
