Description

PRINCO’s model L2000 radio frequency (RF) point level controller is truly an outstanding value. It combines rugged construction, quick, easy installation  and all the features you need for years of effective, accurate performance.

Operating on the RF impedance sensing principle, the L2000 will detect the   presence (high level) or absence (low level) of a wide variety of materials. It may be made fail-safe in either high or low mode. It will operate in conjunc- tion with process materials that range from low dielectric  (insulating) prod-  ucts such as refined oils, to conductive slurries.

The L2000 incorporates Princo’s user-oriented features - reliability, true

coating cancellation capability, explosion-proof/weatherproof enclosures, RFI immunity, heavy duty relays, easy-on Teflon/316 SS probes and our unique   10-yeqr warranty.

The L2000 has everything you need at a price no higher than the “also rans”

Princo, one of the pioneers of RF level sensing technology, has provided

accurate, dependable, long lived service for thousands of applications in all types of industries, worldwide for more than 4 decades.

Applications

•          Water-based liquids

•          Acids

•          Hydrocarbons and solvents

•          Powders and granulars

•          Oils

Features

 Economical – Low in cost, yet packed with all the features needed for accurate, dependable service.

 NULL-KOTE? Circuitry – Negates effects of conductive coating build-up.

 Designed to Survive – RF immune, vibration-proof, all circuit boards are conformally coated (tropical- ized) for extra protection.

 Easy-On Probe Connection – Automatically provides simple, fast installation and reliable operation without wires, connectors, or terminal strips. Simply screw probe into the housing.

 Unique Status Indicator – Red / green LED shows presence or absence of material and also indicates power “on”

 Heavy Duty Relay – 2 sets of form C contacts rated at 5A, 115 Vac resistive contacts

 High or Low Fail-Safe – Field selectable.

 Heavy-Duty Cast Aluminum Housing – Weatherproof: NEMA 4

 Wide Temperature Range – Standard process temperature: -300 to 500°F (-184 to 260°C).

ROLLOCK PROBES – No part of the probe can fall into the process or be blown from the mounting. No re-tightening of seals required.

Time-Delay – 0 to 30 second delay minimizes relay chatter

                       Ten-Year Warranty – The only level instruments available with this unique assurance of quality.
