© Siemens AG 2016 Level Measurement Continuous level measurement - Radar transmitters SITRANS LR260 ■ Overview ■ Configuration Min. clearance: 10 (0.4) Mounting on a nozzle 4 Min. 1 000 (39) Installation SITRANS LR260 is a 2-wire 25 GHz pulse radar level transmitter for continuous monitoring of solids and liquids in storage vessels including extreme levels of dust and high temperatures, to a range of 30 m (98.4 ft). ■ Benefits Emission cone • Graphical local user interface (LUI) makes operation simple with plug-and-play setup using the intuitive Quick Start Wizard • LUI displays echo profiles for diagnostic support • 25 GHz high frequency allows for small horn antennas mounted easily in nozzles • Communication using HART or PROFIBUS PA • Process Intelligence signal processing for improved measurement reliability and Auto False-Echo Suppression of fixed obstructions • Programming using infrared Intrinsically Safe handheld programmer or SIMATIC PDM Beam angle: 2" horn = 15° 3" horn = 10° 4" horn = 8° ■ Application SITRANS LR260 includes a graphical local user interface (LUI) that improves setup and operation using an intuitive Quick Start Wizard, and echo profile displays for diagnostic support. Startup is easy using the Quick Start wizard with a few parameters required for basic operation. Positioning with Easy Aimer SITRANS LR260’s unique design allows safe and simple programming using the Intrinsically Safe handheld programmer without having to open the instrument’s lid. SITRANS LR260 measures virtually any solids material to a range of 30 m (98.4 ft). • Key Applications: cement powder, plastic powder/pellets, grain, flour, coal, solids and liquids bulk storage vessels, and other applications SITRANS LR260 installation, dimensions in mm (inch) Siemens FI 01 · 2016 4/273 © Siemens AG 2016 Level Measurement Continuous level measurement - Radar transmitters SITRANS LR260 ■ Technical specifications Design Mode of operation 4 Measuring principle Frequency Minimum detectable distance Maximum measuring range1) Pulse radar level measurement K-band (25.0 GHz) 0.05 m (2 inch) from end of horn Enclosure • Construction • Conduit entry Degree of protection Solids • 2" horn: 10 m (32.8 ft) • 3" horn: 20 m (65.6 ft) • 4" horn: 30 m (98.4 ft) Weight Liquids • 2" horn: 20 m (65.6 ft) • 3" horn: 30 m (98.4 ft) • 4" horn: 30 m (98.4 ft) Display (local) Output - HART Power 4 ... 20 mA (± 0.02 mA accuracy) Fail signal Nominal 24 V DC (max. 30 V DC) Load 3.6 mA ... 23 mA; or last value 230 ... 600 Output - PROFIBUS PA • Per IEC 61158-2 • 15.0 mA • Profile version 3.01, Class B Performance (according to reference conditions IEC60770-1) Maximum measured error (including hysteresis and non-repeatability) Rated operating conditions Installation conditions Location Ambient conditions (enclosure) • Ambient temperature • Installation category • Pollution degree Flange and horn (easy aimer model) • Material • Horn antenna Process connections • Universal flanges 2) Indoor/outdoor • Materials General Radio Hazardous -40 ... +80 °C (-40 ... +176 °F) I 4 Process temperature r > 1.6, antenna and application dependent -40 ... +200 °C (-40 ... +392 °F) Process pressure • 0.5 bar g (7.25 psi g) maximum • 3 bar g (43.5 psi g) optional with 80 °C (176 °F) temperature max CSAUS/C, CE, FM Europe (R&TTE), FCC, Industry Canada, RCM CSA/FM Class II, Div. 1, Groups E, F, G, Class III ATEX II 1D, 1/2D, 2D Ex ta IIIC T100 ºC Da IECEx/ATEX II 1 GD Ex ia IIC T4 Ga, Ex ta IIIC T100 ºC Da CSA/FM Class I, II, III, Div. 1, Groups A, B, C, D, E, F, G SABS ARP0108 Ex ia IIC T4 Ga Handheld communicator HART communicator 375 PC SIMATIC PDM Display (local) Graphic local user interface including quick start wizard and echo profile displays 2) Siemens FI 01 · 2016 2" NPT (ASME B1.20.1), R (BSPT, EN 10226-1) or, G (BSPP, EN ISO 228-1) 316L/1.4404 or 316L/1.4435 stainless steel PTFE emitter Programming Intrinsically Safe Siemens handheld Infrared receiver programmer • Approvals for handheld programmer IS model: ATEX II 1GD Ex ia IIC T4 Ga Ex iaD 20 T135 °C Ta = -20 ... +50 °C CSA/FM Class I, II, and III, Div. 1, Groups A, B, C, D, E, F, G, T6 Ta = 50 °C 1) 4/274 2 inch/50 mm, 3 inch/80 mm, 4 inch/ 100 mm, 6 inch/150 mm Certificates and approvals Medium conditions Dielectric constant r 304 stainless steel 2" horn 3" horn 4" horn Mechanical (Threaded Connection model) • Threaded connection • 25 mm (1 inch) from minimum detectable distance to 300 mm (11.8 inch) • Remainder of range = 6 mm (0.23 inch) or 0.05 % of spa (whichever is greater) Aluminum, polyester powder-coated 2 x M20 x 1.5 or 2 x ½" NPT Type 4X/NEMA 4X, Type 6/ NEMA 6, IP67, IP68 < 8.14 kg (17.9 lb) including 4" flange and standard Easy Aimer with 4" horn antenna Graphic LCD, with bar graph representing level From sensor reference point Universal flange mates with EN 1092-1 (PN 16)/ASME B16.5 (150 lb)/ JIS 2220 (10K) bolt hole pattern © Siemens AG 2016 Level Measurement Continuous level measurement - Radar transmitters SITRANS LR260 Selection and Ordering data Article No. Selection and Ordering data SITRANS LR260 2-wire, 25 GHz pulse radar level transmitter for continuous monitoring of solids to a range of 30 m (98.4 ft).
