266 DDS Digital Diaphragm Seal - HART Version
Pressure transmitters
Introduction
—
266 DDS models
The present manual provides information on
installing, operating, troubleshooting the 266 digital
diaphragm seal (DDS) configuration, a solution
based on the existing 266 gauge and absolute
pressure transmitter models. 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.
The pressure transmitters model 266DDS is a
modular range of field mounted, microprocessor
based electronic transmitters, using multiple sensor
technologies. Accurate and reliable measurement of
gauge for gas ad 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 to 20mA
with HART digital communication.
Engineered solutions for all
applications
Measurement made easy
