SITRANS LR250 Hygienic Encapsulated Antenna
■ Overview
■ Application
SITRANS LR250 includes a graphical local user interface (LUI)
that improves set-up and operation by including an intuitive
Quick Start Wizard, and echo profile displays for diagnostic
support. Startup is easy using the Quick Start wizard with few
parameters required for basic operation.
The 25 GHz frequency creates a narrow, focused beam allowing
for smaller antenna options and decreasing sensitivity to
obstructions.
SITRANS LR250’s unique design allows safe and simple programming using the Intrinsically Safe handheld programmer
without having to open the instrument’s lid.
The SITRANS LR250 Hygienic Encapsulated Antenna is a 2-wire
25GHz pulse radar level transmitter with sanitary and hygienic
approvals for continuous monitoring of liquids, slurries, and
pastes within the food, beverage, chemical, and pharmaceutical
industries to a range of 20 m (66 ft) (antenna dependent).
Picture shown with accessories sold separately.
■ Benefits
• Fully encapsulated horn antenna design with FDA approved
and USP Class VI compliant, TFM 1600 PTFE lens
• < 0.8  Ra surface finish for maximum cleanability and
hygiene requirements commonly required in sanitary environments
• Chemically resistant TFM 1600 PTFE lens is also suitable for
aggressive or corrosive materials
• Approved device in accordance with 3-A, EHEDG EL Class I
and/or EHEDG EL Aseptic Class I
• Cost effective replacement for transmitters made of exotic
materials
• Graphical local user interface (LUI) makes operation simple
with plug-and-play set-up using the intuitive Quick Start
Wizard
• Industry standard process connections including ISO 2852,
DIN 11851, DIN 11864-1, DIN 11864-2, DIN 11864-3, and
Tuchenhagen Varivent Type F and N
• LUI displays echo profiles for diagnostic support
• 25 GHz high frequency and 2 inch (50 mm) process
connection/antenna allow for easy mounting
• Insensitive to mounting location and obstructions, and less
sensitive to nozzle interference
• Communication using HART, PROFIBUS PA, or FOUNDATION
Fieldbus
• Process Intelligence signal processing for improved
measurement reliability and Auto False-Echo Suppression of
fixed obstructions
• Programming using infrared Intrinsically Safe handheld
programmer or over a network using SIMATIC PDM, Emerson
AMS, or Field Device Tools such as PACTware or Fieldcare via
SITRANS DTM.
• Functional Safety (SIL 2). Device suitable for use in accordance with IEC 61508 and IEC 61511
SITRANS LR250 measures superbly in small vessels and in
tanks/vessels up to 20 m (66 ft) on materials with dk > 1.6.
• Key Applications: applications within the food, beverage,
chemical and pharmaceutical industries where sanitary,
aseptic, or hygienic approvals are required or easy install/
clean flush antennas are preferable such as ice cream, fruit
juice, milk, beer, and pharmaceutical or chemical additives
and ingredients.
■ Configuration
Installation
Note:
• Beam angle is the width of the
cone where the energy density
is half of the peak energy
density.
• The peak energy density is
directly in front of and in line
with the antenna.
• There is a signal transmitted
outside of the beam angle;
therefore false targets may be
detected.
