Ø21.3 (¾ thread) Ø42.4 (1½ thread) probe length mm ( inches) ØD Function Features Measurement independent of density, temperature and dust Measurement also possible with foam on the surface Simple, menu-guided on-site operation with four-line plain text display On-site envelope curve on the display for easy diagnosis Easy operation, diagnosis and measuring point documentation with the supplied operating program Optional remote display and operation With coax probes the measurement is completely independent of internals in the tank and of the installation in the nozzle Up to SIL2 acc. to IEC 68 The Pulscon LTC performs continuous level measurement of powdery to granular bulk solids e. g. plastic granulate and liquids. Probes are available with threaded process connections from ¾ and flanges from DN40/1½ : Rope probes, above all for measurement in bulk solids, measuring range up to 35 m/1378 in Rod probes, above all for liquids Coax probes, for liquids The following interfaces are available for system integration: HART (standard), 4 ma ma PROFIBUS PA FOUNDATION Fieldbus Electrical connection Example: 2-wire connection IH More connection types see section electrical connections. 4 ma ma Auxiliary voltage 1 2 L- L+ alternative 3 I+ I- HART modem Communication resistor ( 250 Ω) 4 Test socket (output current) Pepperl+Fuchs Group Tel.: Germany USA Singapore Internet 1 Application Function principle Function and system design Measuring principle Equipment architecture Input characteristics Measured variable Measurement range Blocking distance Measuring conditions Output characteristics Output signal Signal on alarm Linearisation Auxiliary energy Electrical connection Supply voltage Power consumption Current consumption Overvoltage protection Residual ripple Terminal assignment Load Performance characteristics Resolution Response time The Pulscon LTC is a transmitter for continuous level measurement in powdery to granular bulk solids and liquids. The distance from the reference point (process connection of the measuring device) to the product surface is measured. High-frequency pulses are injected to a probe and led along the probe. The pulses are reflected by the product surface, received by the electronic evaluation unit and converted into level information. The Pulscon LTC is a measuring system that functions according to the time-of-flight method. The distance from the reference point (process connection of the measuring device) to the product surface is measured. The Pulscon LTC is usable as single measuring cell or integrated in PROFIBUS PA or FOUNDATION Fieldbus systems. distance between a reference point and a reflective surface (e. g. medium surface) max. 35 m (115 ft), dependent on the medium, the probe type and the probe length - rod probe 6 mm: m ( ft) - rod probe 16 mm/coax probe: m ( ft) - rope probe: m ( ft) for details see technical information The upper blocking distance (= UB) is the minimum distance from the reference point of the measurement (mounting flange) to the maximum level. The lower blocking distance (= LB) is the range of the probe from the lower edge calculated upwards, in which exact measurement is not possible. The utilisable measuring range amounts between lower blocking distance and upper blocking distance the empty distance value and the measuring range value can be tuned independent from it. - rod probe 6 mm: 0.2 m (8 in) - rod probe 16 mm: 0.2 m (8 in) - coax probe: 0 m - rope probe: 0.2 m (8 in) for details see technical information used frequency spectrum: GHz ma with HART protocol PROFIBUS PA FOUNDATION Fieldbus (FF) error information can be accessed via the following interfaces: - local display with error symbol, plain text display - current output - digital interface The Pulscon LTC linearisation function enables conversion of the measured value into any desired length or volume unit, mass or %. Linearisation tables for volume calculation in cylindrical tanks are pre-programmed. Any other table from up to 32 value pairs can be input manually or semi-automatically. connection IH: ma with HART, 2-wire connection AH: ma with HART, 4-wire active, AC version connection DH: ma with HART, 4-wire active, DC version connection PA: PROFIBUS PA connection FF: FOUNDATION Fieldbus connection IH: V DC; Ex version: V DC connection AH: V AC connection DH: V DC mw connection AH: approx ma connection DH: approx. 100 ma connection PA: max. 11 ma connection FF: max. 15 ma If there is the risk of differences in potential forming when installing the Pulscon LTC to measure the level of flammable liquids, the device can be fitted with a T12 housing and integrated overvoltage protection (600 V gas tube surge arrester), see ordering information.
