© Siemens AG 2016 Level Measurement Continuous level measurement - Radar transmitters SITRANS Probe LR ■ Overview ■ Configuration Installation Min. 300 mm (1 ft) for every 3 m (10 ft) of vessel wall 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 rod antenna. Beam angle 28° 4 SITRANS Probe LR is a 2-wire, 6 GHz pulse radar level transmitter for continuous monitoring of liquids and slurries in storage vessels with nominal pressure and temperature, to a range of 20 m (66 ft). Mounting unit on vessel ■ Benefits • Uni-Construction polypropylene rod antenna standard • Easy installation and simple start up • Programming using infrared Intrinsically Safe handheld programmer, SIMATIC PDM or HART handheld communicator • Communication using HART • Process Intelligence signal processing • Auto False-Echo Suppression of false echoes Conical Mounting on a manhole cover Flat Parabolic Mounting on a nozzle ■ Application Probe LR is designed for safe and simple programming using the Intrinsically Safe handheld programmer without having to open the instrument’s lid. It has a standard Uni-Construction polypropylene rod antenna that offers excellent chemical resistance and is hermetically sealed. The Uni-Construction antenna includes an internal, integrated shield that eliminates vessel nozzle interference. SITRANS Probe LR incorporates Process Intelligence signal processing. The Probe LR also has a high signal-to-noise ratio leading to improved reliability. Min. 10 (0.4) The Probe LR is ideal for applications with chemical vapors, temperature gradients, vacuum or pressure, such as simple chemical storage or water treatment vessels. SITRANS Probe LR has a range of 0.3 to 20 m (1 to 65 ft). Min. 100 (4) SITRANS Probe LR shield length 100 (4) or 250 (10) standard lengths SITRANS Probe LR installation, dimensions in mm (inch) Startup is easy with as few as two parameters for basic operation. Programming is simple using SIMATIC PDM, HART handheld communicator or the Intrinsically Safe handheld programmer. • Key Applications: chemical storage, wastewater wet well, and drilling mud Siemens FI 01 · 2016 4/197 © Siemens AG 2016 Level Measurement Continuous level measurement - Radar transmitters SITRANS Probe LR ■ Technical specifications Power supply Mode of operation Measuring principle Pulse radar level measurement Frequency 5.8 GHz (North America 6.3 GHz) Measuring range 0.3 ... 20 m (1.0 ... 65 ft) Output Analog output 4 ... 20 mA Accuracy ± 0.02 mA Span Proportional or inversely proportional Communications HART Performance (reference conditions) 4 Accuracy ± the greater of 0.1 % of range or 10 mm (0.4 inch) Influence of ambient temperature 0.003 %/K Repeatability ± 5 mm (2 inch) Fail-safe mA signal programmable as high, low or hold (LOE) Rated operating conditions Installation conditions • Location Ambient conditions (enclosure) • Ambient temperature • Installation category • Pollution degree Certificates and approvals General CSAUS/C, CE, FM, RCM Marine • Lloyd's Register of Shipping • ABS Type Approval Radio FCC, Industry Canada, and European (R&TTE), RCM Hazardous • Intrinsically Safe (Brazil) • Intrinsically Safe (Canada) • Intrinsically Safe (Europe) • Intrinsically Safe (International) • Intrinsically Safe (Russia/Kazakhstan) • Intrinsically Safe (USA) Indoor/outdoor -40 ... +80 °C (-40 ... +176 °F) I 4 Dielectric constant r r > 1.6 (for r < 3, use stillpipe) Vessel temperature -40 ... +80 °C (-40 ... +176 °F) Vessel pressure 3 bar g (43.5 psi g) Design PBT (Polybutylene Terephthalate) PEI (Polyether Imide) 2 x M20 x 1.5 or 2 x ½" NPT with adapter Degree of protection Type 4X/NEMA 4X, Type 6/NEMA 6, IP67, IP68 Weight 1.97 kg (4.35 lb) Antenna • Material Polypropylene rod, hermetically sealed construction Standard 100 mm (4 inch) shield for maximum 100 mm (4 inch) nozzle or optional 250 mm (10 inch) long shield • Dimensions Process connections 4/198 Siemens FI 01 · 2016 INMETRO Ex ia IIC T4 Ga CSA Class I, Div. 1, Groups A, B, C, D; Class II, Div. 1, Group G; Class III ATEX II 1G EEx ia IIC T4 IECEx Ex ia IIC T4 EAC Ex ia FM Class I, Div. 1, Groups A, B, C, D; Class II, Div. 1, Groups E, F, G; Class III Programming Handheld programmer HART communicator 375 PC SIMATIC PDM Intrinsically safe Siemens handheld programmer (optional) • Approvals (handheld programmer) Infrared receiver Display (local) Multi-segment alphanumeric liquid crystal with bar graph (representing level) available in four languages Medium conditions Enclosure • Body construction • Lid construction • Cable inlet • Nominal 24 V DC with max. 550 , maximum 30 V DC • 4 ... 20 mA 1½" NPT [(Taper), ANSI/ASME B1.20.1] R 1½" [(BSPT), EN 10226] G 1½" [(BSPP), EN ISO 228-1] ATEX II 1G EEx ia IIC T4 CSA and FM Class I, Div. 1, Groups A, B, C, D, T6 at max. ambient © Siemens AG 2016 Level Measurement Continuous level measurement - Radar transmitters SITRANS Probe LR Selection and Ordering data SITRANS Probe LR 2-wire, 6 GHz pulse radar level transmitter for continuous monitoring of liquids and slurries in storage vessels with nominal pressure and temperature, to a range of 20 m (66 ft).
