SLC

Product catalog summary

General Characteristics
The SLC series level probes feature built-in management electronics, eliminating the need for auxiliary circuits to control alarms or actuators. These static probes, devoid of moving parts, offer precise liquid level control by measuring the liquid's conductivity. The system operates with low potential and alternating currents to prevent electrode incrustation and tank perforation, which are common with direct currents.

Control and Adjustment
ELECTRA SLC-10
To control, open the case and short circuit terminals 1 and 3. The relay should switch on, and the LED should light. For sensitivity adjustment, install the unit on the tank, submerge the electrode, and adjust the trimmer until the relay switches.
ELECTRA SLC-50
For control, short circuit terminals 11 and 13, and 3 and 11, ensuring the corresponding LEDs light and relays switch. Sensitivity adjustment involves submerging electrodes and adjusting the trimmer until the red LED lights and the relay switches.

Nomenclature
The nomenclature includes details such as name, type, process connection, sensitivity, electrode length and coating, degree of protection, and power supply.

Catalog excerpts

GENERAL CHARACTERISTICS The level probes SLC series have the built-in management electronics and do not require auxiliary circuits to control alarms and / or actuators. The probes, being of a static type, without moving parts, allow an extremely precise control of the level of liquid. The system is based on measurement of the conductivity of the liquid to be controlled and works with low potential and with alternating currents, in order to avoid the incrustation of the electrodes and / or perforation of the tank normally caused by the use of direct currents, which cause a galvanic action on materials. The contact of the electrode with the liquid under control determines the actuation of a relay inside the control unit. • AISI-316 Stainless steel electrodes • Built-in electronics • Relay output Electrical connection Internal terminal board Ground Electrode Option Power supply Coating Polyolefin Process connection Dimension 3/8” Male thread UNI 228/1 Material Brass Code Options 1x0100 Length L We reserve the right to change the data without notice
