Applications
• Water-based liquids
• Acids
• Hydrocarbons and solvents
• Powders and granulars
• Oils
Features
• Remote Sensor Mounting – Eliminates the need to work in high places, hazardous locations, or inclem- ent weather. Control unit can be up to 3000 feet from sensor and used ordinary twisted pair cable.
• Universal – Wide range of point level applications. Detects the level of powders, granules, conductive or non-conductive liquids … even the sticky ones.
• NULL-KOTE™ Circuitry – Negates effects of coating build-up.
• High Sensitivity and Temperature Stability – For critical low response applications.
• 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.
• 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.
