TEMPERATURE AND
PRESSURE RATINGS
Flange Temperature
The temperature at the flange is limited by the antenna, the tank seal, and
O-rings (if applicable). The continuous flange temperature range is presented
for each antenna in section “Dimensional Drawings and Mechanical
Properties” on page A-5.
Figure A-1. Temperature rating
considerations.
NOTE!
Flange temperature depends on process and ambient temperature, as well as
mounting conditions such as nozzle position, distance to maximum product
level, nozzle height, presence of insulation, etc.
Operating Pressure
The pressure in the tank is limited by a combination of the antenna and the
process connection.
The following 5400 Series flanges have the same p/T rating as the
corresponding blind flanges:
ANSI
: according to ANSI B16.5 Table 2-2.3.
EN
: according to EN 1092-1 Table 18, material group 13E0.
The continuous operating pressure range is presented for each antenna in
section “Dimensional Drawings and Mechanical Properties” on page A-5.
Electronics Temperature
There are restrictions on the ambient temperature (see “Specifications” on
page A-1). The ambient temperature may also be limited by the selected
product certificate (see “Product Certifications” on page B-1).
