    The DI35 Powered Process Indicators are advanced instruments which have been designed and manufactured to stringent specifications.

    The instruments have been designed to accept all the standard analogue process signals. The input measurement is shown on a high contrast LED display. The DI35 incorporates an LSI CMOS 2000 count dual slope integrating analogue to digital converter which is designed to reject electrical interference that normally abounds in industrial environments. The front panel of the DI35 series are sealed to IP65 and the instrument includes screw terminal electrical connection.
