Universal PRINCO’s RF Impedance technology is ideal for a wide range of applications, from non-conductive, dielectrics, to highly conductive materials Easy-On Probe Automatically provides simple, fast installation and reliable operation without wires, connectors, or terminal strips. Easy to Configure • Tank shape ~ volume output • Level & volume units • Normal/reverse acting • Level/volume proportional • Damping • Maintenance • Polling address
High Sensitivity & Stability For critical low response applications. | Designed to Survive RF immune, vibration-proof, and factory precalibrated - at no extra cost. Easy to Install Integral electronics install as single unit. No special cable, delicate connectors, or separate enclosure. Operational Modes Stand Alone Operation Easy Calibration Push-Button Empty & Fill Remote Operation Via Hart® Protocol Universal Hart® interface Monitor actual level and volume in engineering units Monitor output current range (% range, level or volume proportional) milliamps or as a percentage. |
Princo’s SMART 2™ (L4620) is a two-wire HART" level transmitter that can be used for most liquid and light bulk solid applications. All features are accessible through the HART" compliant Device Description (DD) using a standard Model 275 HART" hand held or from any HART" protocol compliant system. The SMART 2™ has built-in 20 point linearization for the measurement of level and volume in any shape vessel. The unit is PTB, SEV (CENELEC) approved for intrinsic safety (EEx ia [IC T6) which enables operation in hazardous locations. |
Easy installation, set-up, and maintenance reduces overall operating costs substantially. A complete level system consists of the SMART 2™ used in conjunction with the appropriate L100 series probe as illustrated on PRINCO’s Probe Data Sheet. Span Range Probe lengths from 1 inch to 200 feet, depending upon application. (From 5 pF to 3,000 pF) Output 4 to 20 mA (Point-to-Point) 4 mA (Multidrop)
Hart® Protocol Linearity / Accuracy ± 0.5% typical
Load 250 ... 750 ohms
Hart® Protocol Simultaneous transmission of 4-20 mA dc signal (500 ohm load) and digital FSK signal on one twisted pair. Digital series bit stream permits two-way communication, but does not affect or alter 4-20 mA analog signal.
Electronics Housing Explosion-proof Class I, II, III, Div. 1, Groups C, D, E, F, & G NEMA 4.
