L3522, Level Sentry Point Level Controller

PRINCO’s Level Sentry L3522 level controller is a microprocessor-based, RF impedance level switch. It incorporates Level Sentry, a unique feature that automatically, once every minute, performs a self-test for a potential circuit failure. In many installations, a point level controller could go for an extended period of time without ever being required to detect an alarm condition. Level Sentry ensures that when the unit is called upon, it will detect
the alarm condition.

Conformally coated electronics, NULL-KOTE™ circuitry, explosion-proof/weatherproof enclosures, ROLLOCK™ probe construction and our unique 10 Year Warranty mean the ultimate in reliability. Excellent sensitivity, coupled with stability of 1 picofarad over the entire operating range, gives you a true set and forget installation.
