1 Introduction

1.1Description

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.
