Description

PRINCO’s model L2000S 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 L2000S 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 L2000S incorporates Princo’s user-oriented features - reliability, true coating cancellation capability, explosion-proof/weatherproof enclosures, RFI

immunity, heavy duty relays, easy-on Teflon/304 SS probes and our unique 10-yeqr warranty.

The L2000S 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.

• Special 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 8A, 250 Vac resistive contacts

• High or Low Fail-Safe – Field selectable.

• Heavy-Duty Cast Aluminum Housing – Weatherproof: IP65

• 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.
