CLB UFI Electrical Level Indicators

Description

CLB Series Electrical Level Indicators: Precision and Control for Tanks

The CLB series by UFI Filters offers an effective solution for electrical monitoring of fluid levels in hydraulic tanks. These devices (float switches) activate an electrical signal when the liquid reaches a predetermined threshold (minimum or maximum), enabling the automation of alarms or safety procedures.

Operating Principle and Technology

The heart of the system is a Reed SPDT (Single Pole Double Throw) switch, magnetically actuated by the movement of the float along the rod. This technology ensures precise and long-lasting operation, with no direct mechanical contacts subject to wear.

Design Features and Materials

CLB indicators are built using durable materials suitable for industrial environments:

• Tank connection: Made of anodized aluminum, offering lightness and corrosion resistance.
• Rod: Made of stainless steel, ensuring rigidity and long service life.
• Float: Made of polyamide, a robust and chemically stable material.
• Seals: Standard NBR (Nitrile), suitable for most hydraulic fluids.

Electrical and Operating Specifications

• Contacts: Reed SPDT switch.
• Maximum load: AC up to 48 V – 0.5 A; DC up to 48 V – 0.5 A.
• Electrical connection: Via standard DIN 43650 connector.
• Protection: IP65 protection rating according to DIN 40050.
• Operating temperature: From -10°C to +90°C.

Installation and Variants

Installation requires a minimum distance of 50 mm from ferrous walls to avoid magnetic interference. The maximum supported oil viscosity is 150 cSt. The tank connection is of the “Universal” (U) type, combining a 1″ BSP thread with a 2- or 3-hole flange, offering maximum mounting flexibility.
