  SITRANS P pressure transmitter with supplementary electronics for 4-wire connection

  Direct connection of the supplementary electronics to a SITRANS P pressure transmitter from the DS III HART series produces a transmitter for four-wire connection.

  The supplementary electronics cannot be attached to explosion-protected pressure transmitters. The supplementary electronics is fitted in a light metal housing which is mounted on the left side of the pressure transmitter.

  Note on ordering:

  The supplementary electronics has to be be ordered through the supplementary options of the pressure transmitter in question.
