Continuous level and interface measurement for critical conditions SITRANS LC500 Answers for industry. SITRANS LC500 Power Max. 33 V DC (30 V DC with Intrinsically Safe operation), min. 12 V DC at 3.6 mA, min. 9.5 V DC at 22 mA Performance Measurement range 1 to 3300 pF as standard (1 to 330 pF and 1 to 6600 pF options available*) SITRANS LC500 Span Minimum 3.3 pF Accuracy Deviation < 0.1% of measured value SITRANS LC500 is an inverse frequency shift capacitance level or interface transmitter with active shield for critical applications, such as high-pressure coalescers, FPSO ships, LNG processing plants, and offshore oil and gas platforms. It performs in liquids, solids, interfaces, and foam and is unaffected by vapors, product deposits, dust, or condensation and is highly resistant to toxic and aggressive materials. SITRANS LC500 is the right solution if you’re looking for high-precision level or interface measurement under extreme conditions. Non-linearity and repeatability < 0.1% of range and actual measured value respectively Temperature stability 0.15 pF (0 pF) or < 0.25% (typically < 0.1%) of actual measured value, whichever is greater over the full temperature range Safety • Galvanically isolated inputs / outputs • Fully potted Diagnostics with fault alarm when: • Primary variable (PV) out of limits • Watch dog • System failure in measurement circuit • Self-checking facility • Deviation between A/D and D/A converter • Check sum Process connections • Threaded: NPT [(Taper), ANSI/ASME B1.20.1], R [(BSPT), EN 10226/PT (JIS-T), JIS B 0203], G [(BSPP) EN ISO 228-1/PF (JIS-P), JIS B 0202] • Flange: ASME, EN 1092-1 • Full function diagnostics comply with NAMUR NE 43 Process material • 316L (1.4435 or 1.4404) stainless steel* Probe diameter • Rod version: 16 mm (0.63"), or 24 mm (0.95")** • Cable version: 9 mm (0.35") with PFA jacket, 6 mm (0.24") without PFA jacket Probe length • Rod version: max. 3.5 m (138") with 16 mm (0.63") diameter rod, max. 5.5 m (216") with 24 mm (0.95") diameter rod • Cable version: 35 m (1378") Probe insulation PFA (standard), enamel • Polarity-insensitive current loop • Integrated safety barrier Interface Output Galvanically isolated 4 to 20 mA / 20 to 4 mA • Loop current 3.6 to 22 mA / 22 to 3.6 mA (2-wire current loop) • Solid state switch 30 V peak AC / 30 V DC, 82 mA Mechanical • Integrated local display to facilitate on-site commissioning and inspection • Standard version handles temperatures from -50 to 200 °C (-58 to 392 °F) and pressures up to 150 bar g (2175 psi g).
