Product Description

The HYDAC FSK-0127-2.4C-00000/O-/M12.000-LED is an FSK series capacitive level sensor/gauge, specifically designed for hydraulic system oil level monitoring. It combines level detection and status indication functions. The following is a detailed overview based on official specifications:

Capacitive Sensing Principle

Level detection is achieved by detecting the difference in dielectric constant between oil and air. Non-contact measurement avoids probe wear and is compatible with most industrial hydraulic oils, lubricating oils, and other insulating media.

Accurate & Stable Detection

High measurement accuracy and good repeatability, minimally affected by medium viscosity and temperature fluctuations (refer to FSK series general standards, temperature compensation range -20℃~+80℃), ensuring reliable level data.

Intuitive Status Feedback

Built-in LED indicator allows for quick assessment of equipment operating status. A 4-20mA analog signal output supports remote level monitoring, catering to both on-site operation and system integration needs.

Compact & Protective Design

Small in size, suitable for confined installation spaces, with an enclosure protection rating meeting industrial standards (estimated IP67), capable of withstanding harsh environments such as industrial dust and humidity.

Typical Applications:

  • Suitable for level monitoring in industrial hydraulic power units, lubricating oil tanks, and hydraulic actuator tanks.
  • Can be installed on the side wall or top of the tank for real-time monitoring of oil levels, preventing system idling and component wear due to insufficient oil.
  • Suitable for industrial automation scenarios requiring remote level data acquisition and on-site status visualization, especially suitable for the level protection needs of compact hydraulic systems.
