Remote Sensor Mounting -Eliminates the need to work in high places, or inclement weather. Control unit can be up to 3000 feet from sensor and uses ordinary twisted pair cable.
Designed to Survive – RF immune, vibration-proof, all circuit boards are conformal coated (tropicalized) for extra protection - at no extra cost.
Excellent Temperature Stability –Less than 0.1pF thermal drift per 20°F (less than 1.0 pF/200°F of ambient temperature change).
Wide Temperature Range –Standard process temperature: -300 to 500°F (-184 to 260°C).
Heavy Duty Relay – 10A 115 VAC resistive contacts.
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 – Indicates both presence or absence of material and power "on" with two color LED.
Universal – Wide Range of Point Level Applications – detects the level of powders, granules, both conductive or non-conductive liquids … even the sticky ones.
High Sensitivity – Extremely sensitive plus very high turn-down: 0.15 pf to 1000 pf.
ROLLOCK™ PROBES – No part of the probe can fall into the process or be blown from the mounting. No re-tightening of seals required.
NULL-KOTE™ Circuitry – Makes the sensor immune to adverse effects from conductive coating build-up.
Hi-Lo Fail-Safe - Field selectable.
Time-Delay Included – 0-30 second delay - no extra cost
Ten-Year Warranty – The only level instruments available with this unique assurance of quality.
Factory Mutual Approval – Class I, II, III, Div.1, Groups C, D, E, F, & G/NEMA 4.
PRINCO’s High-Perform-X L3540 remote level controller provides the right combination of features, reliability, convenience, sensitivity, and cost.
