Cảm biến đo mức Princo Instruments L2631
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 material builds up on the probe. Superior temperature stability and noise immunity, conformally coated circuit boards, self-diagnostics and factory precalibration mean accurate, reliable, easy-to-install level instrumentation.The L2631’s 4 to 20 mA dc output signal is proportional to the process level. Zero and span adjustments are noninteracting. Our Easy-On probe gives you reliable, automatic connection when the probe is screwed into the electronics housing. The need for continuous level measurement is nearly universal in the process industries. Today’s processing plants must operate at peak efficiency, minimize labor and material costs, insure on-time delivery of product and eliminate spills of even marginally hazardous materials. Accurate, reliable, continuous level measurement is a vital part of their operation. In millions of installations, spanning more than 85 years of experience, PRINCO process instruments have provided accurate, dependable, long lived service for all types of industries. • NULL-KOTE™ Circuitry – Makes the sensor immune to adverse effects of conductive coating build up. • Designed to Survive – RF immune, vibration-proof, and conformally coated (tropicalized) circuit boards for additional protection – at no extra cost. • Explosion-Proof/Weatherproof Housing – Class I, II, III, Div.1, Groups C, D, E, F, & G - NEMA 4. • Simple Two-Wire Connection – Means low installation cost and compatibility with most process control systems. • Polarity Reversal Protection • Factory Precalibrated – Field calibration, if needed, is quick and easy.
