Overview

SITRANS LR500 series are 80 GHz radar level transmitters for continuous monitoring of liquids, slurries, and solids in storage and process vessels including high temperature and pressure, to a range of 120 m (393 ft).

Benefits

Continuous level measurement up to 120 m (393 ft)
Easy installation and simple startup
Programming using 4-button HMI, mobile IQ app using Bluetooth, or SIMATIC PDM
IQ Guard for health monitoring, NE107 diagnostic messaging and quality verification report
Communication using HART 7
Graphical HMI with echo profile display and backlight
Near Range Suppression for automatic detection and suppression of material build up noise
Process Intelligence signal processing
1 mm accuracy in accordance with IEC 60770-1
Suitable for API 2350
Auto False Echo Suppression for fixed obstruction avoidance
Low power consumption with EPD (environmental product declaration)
Optional SLOD (second line of defense) for toxic material safety
100 000 points of data logging memory for process control analysis and optimization

Application

SITRANS LR500 series radar level transmitters include a graphical local user interface that improves setup and operation by including an intuitive Quick Start Wizard, and echo profile displays for diagnostic support.
The 80 GHz frequency creates a narrow, focused beam allowing for smaller antenna and decreasing sensitivity to obstructions. SITRANS LR500 series radar level transmitters measure superbly on low dielectric media with high accuracy and repeatability. A very fast measurement response is ideal for process control applications.

Key Applications: SITRANS LR500 Radar level transmitters are available with four antenna types for level measurement of liquid, slurry, and solid materials:
- Threaded lens antenna
- Flanged encapsulated antenna
- Polymeric horn antenna
- Flanged lens antenna
