1. Introduction
1.1 Instruction manual structure
The present manual provides information on installing,
operating, troubleshooting the 266 pressure transmitter. Every
section of the present manual is specifically dedicated to the
specific phase of the transmitter lifecycle starting from the
receipt of the transmitter and its identification, passing to the
installation, to the electrical connections, to the configuration
and to the troubleshooting and maintenance operations.
1.2 Models covered by this manual
The present manual can be used for all the 266 models with
exception done for the 266C (multivariable version).
1.3 Product description
The pressure transmitters model 266 is a modular range of field
mounted, microprocessor based electronic transmitters,
multiple sensor technologies. Accurate and reliable
measurement of differential pressure, gauge and absolute
pressure, flow and liquid level is provided, in the even most
difficult and hazardous industrial environments. Model 266 can
be configured to provide specific industrial output signals
according to 4...20mA with HART digital communication.
