CLB electrical level indicators

UFI Filters Hydraulics presents the updated catalogue of CLB electric level indicators, which are designed to ensure accurate and reliable monitoring of oil levels in hydraulic tanks.

This compact, robust solution is suitable for both industrial systems and mobile machinery.

Main features

  • Robust structure: anodised aluminium tank connection, stainless steel rod and polyamide float ensure mechanical strength and a long life, even in harsh operating conditions.
  • SPDT reed switch electrical contact: automatically detects minimum or maximum oil levels and can safely control loads of up to 48 V AC (alternating current) and 48 V DC (direct current). These values are suitable for direct connection to PLCs (programmable logic controllers) and low-power signalling devices.
  • IP67 protection rating: ideal for installations that require reliability in the presence of dust or humidity.
  • Compatibility with different fluids: suitable for HH, HL, HM, HV and HTG oils according to ISO 6743/4.
  • Wide operating temperature range: guaranteed operation from -15°C to +90°C, which is an important advantage for applications subject to temperature changes or challenging environmental conditions.
  • A wide range of lengths are available, from 150 mm to 500 mm, with mounting and configuration options to suit different plant solutions.

Typical applications

CLB level indicators are used in a wide range of hydraulic systems, where controlling the oil level is essential for preventing downtime and damage to components.

The most common applications include:

  • Tanks for industrial and mobile machinery, such as presses, hydraulic power units, lifting platforms, and material handling equipment.
  • Filtration and lubrication systems, where maintaining the correct fluid level is essential for preserving efficiency and operational continuity.
  • Machine tools and process plants, including cooling systems, lubrication and cooling circuits, and fluid treatment units.
  • Pump protection applications, where avoiding dry running is essential to protect the pump and the mechanical components of the circuit.
  • Systems with large-volume tanks, where reliable signalling systems are essential for managing the risk of overflow.

Benefits for the user

  • Constant and automatic oil level monitoring.
  • Prevention of damage to pumps and hydraulic components.
  • Reduction of maintenance costs and operational risks.
  • Simple installation and immediate integration into control systems.
