IGSITRPDS3-1
Installation Guide
INSTALLATION
Transmitter mechanical and electrical installation is outlined in this section.
IMPORTANT
Before installing or servicing the transmitter:
•
Read the information on the transmitter’s rating and approval plates and ensure that the correct model
is at hand and that the correct procedures in this guide and User’s Manual UMSITRPDS3-1 are
followed. Refer to the User’s Manual, Section 9.1 Model Designations for an explanation of the
model designation alphanumeric sequence shown on the rating plate.
•
The installation must conform to the National Electrical Code and all other applicable construction
and electrical codes. Refer to the installation drawings in the User’s Manual, Appendix B when
locating a transmitter in a hazardous area.
•
For hazardous area installations, refer to the current revision of the User’s Manual. Refer to Section
9.6 Hazardous Area Classifications for approval agency requirements that affect installation and use
of the instrument and for additional statements concerning installation in a hazardous environment.
•
Refer to Section 2 Installation in the User’s Manual for installation diagrams that show suggested
mounting locations and pipe runs for various transmitter models, measurement methods, and process
fluids. Actual mounting position for a specific application can be important to system performance.
Mechanical Installation
Figures 1 through 4 show the transmitter models and the optional mounting bracket kits. Transmitter
dimensions are given in the User’s Manual. A gauge or differential transmitter can be mounted with an
optional bracket kit or with a user supplied bracket. A gauge transmitter can also be mounted in a PMC-
style process connection, as shown in Figures 9 thru 12, and a differential transmitter can be nipple
mounted on an orifice flange. A liquid level transmitter can be flange mounted directly on a vessel, at the
point of measurement.
Mount a transmitter in any position (orientation). The mounting position can cause a zero shift, however,
any zero shift is simply calibrated out with the transmitter installed in its final mounting position. Refer to
the User’s Manual, Section 7 Calibration and Maintenance for details.
The transmitter enclosure can be rotated relative to the measuring cell to clear an obstruction or to allow
viewing the optional display. The display can then be rotated in 90° increments for ease of reading. Refer
to the following paragraphs for details.
