Introduction

1.1

Description

The RPT 301 Digital Output Pressure Transducer measures air pressure
applied to the connection port and produces an electrical output.  It
comprises a resonant sensor connected to a printed circuit board to
produce a serial digital output and is contained in a metal enclosure to
IP65 standard.  The instrument is designed to communicate with
compatible equipment using a serial communications system which
can be selected by the user for either RS232 or RS485 standard
communications interface.  The power supply for the instrument is a
wide tolerance DC voltage with a low power consumption  A remote
start-up facility enables the instrument to be remotely switched on and
off to save power.
