L2631

Widest Range of Applications – the ideal two-wire level transmitter, it will operate in conjunction with process materials which range from low dielectric (insulating) products, such as refined oils, to conductive slurries; even sticky materials that tend to cling to the sensor. NULL-KOTE™ Circuitry – Makes the sensor immune to adverse effects of conductive coating build up. Designed to Survive – RF immune, vibration-proof, and conformal coated (tropicalized) circuit boards for additional protection – at no extra cost. Ten-Year Warranty – The only level instruments available with this unique assurance of quality. Simple Two-Wire Connection – means low installation cost and compatibility with most process control systems. Polarity Reversal Protection	Factory Mutual System Approval Intrinsically Safe – when used with appropriate power source or PRINCO S939 barriers. Explosion-Proof/Weatherproof Housing – Class I, II, III, Div.1, Groups C, D, E, F, & G - NEMA 4. Factory Precalibrated – Field calibration, if needed, is quick and easy. No interaction between span and zero. Easy to Install – Probe and electronics install as single unit. No cable, delicate connectors, or separate enclosure. Built-In Self Diagnostics – provides assurance that the system is working properly. Easy-On Probe Connection – Automatically provides simple, fast installation and reliable operation without wires, connectors, or terminal strips. Simply screw probe into the housing.
PRINCO’s L2631 NULL-KOTE™ two-wire RF level transmitter can be used to measure the level of virtually any process material, from low dielectric (insulating) products, such as refined oils, to conductive slurries – even viscous materials that cling to the probe. Advanced NULL-KOTE™ circuit design means accurate readings even when conductive materials build up on the probe. Superior temperature stability and noise immunity, conformal coated circuit boards, self-diagnostics and factory precalibration means accurate, reliable, easy-to-install level instrumentation.
The L2631’s 4-20 mA dc output signal is proportional to the process level. Zero and span adjustments are non-interacting. Our Easy-On probe gives you reliable, automatic connection when the probe is screwed into the electronics housing. Span Range From 20 pF to 50,000 pF. Probe lengths from 1 inch to 200 feet, depending upon application. Output Signal 4 to 20 mA dc. Power Requirements 24 Vdc typical. 48 Vdc maximum. Operating Temperature Range -30 to 150°F (-34 to 66°C) Temperature Stability ±0.015% per 1°F Intrinsic Safety Model L2631-IS is intrinsically safe when used with an appropriate power source or PRINCO S939 safety barriers.
