Application Flexibility with Guided Wave Radar
Press release date: January 15, 2014
Four basic versions and wide-ranging configuration options cover a particularly broad application spectrum in all process industries
Also suitable for use in hygienic applications and in harsh environments
With its new Sitrans LG series, Siemens is offering a flexible portfolio of guided wave radar transmitters suitable for virtually any type of industrial application. The modular design of the four basic versions Sitrans LG240, Sitrans LG250, Sitrans LG260 and Sitrans LG270, with numerous configuration options, allows for level measurement in the oil and gas, chemical, pharmaceutical as well as food and beverage industries. The modular radar transmitter covers a broad application spectrum for the measurement of liquids and interfaces, from aggressive materials to hygienic conditions and complies with SIL2 safety standard.
Sitrans LG240 was specifically designed for hygienic applications in the pharmaceutical or food and beverage industries and has the required EHEDG, FDA and 3A certificates. The Sitrans LG250 is ideal for the wide range of liquid level measurement such as those in water treatment applications. The Sitrans LG260 version accurately measures levels of solids, granulates and powders even with extreme dust. In particularly harsh environments with high temperatures up to 450 degrees Celsius (842 °F) or high pressures up to 400 bar (5800 psig), such as those in the chemical or petrochemical industry, the Sitrans LG270 is the best choice.
Sitrans LG's high frequency microwave pulses are transmitted down a rod or cable, offering reliable measurement with up to two millimeter (0.08 inch) accuracy in applications with corrosive vapors, steam, foam, surface agitation and/or liquids with high viscosity, low level, and varying dielectric or density.
Installation is simple with the device's range of pre-configured options, such as customized enclosure materials, process connections, approvals and communication options. Users will be operational in minutes with four-button programming directly at the instrument or through remote configuration with Siemens Simatic PDM (Process Device Manager) via HART communications protocol.
