IP68 Capacitive Level Sensor — Submersible Stainless Steel Gauge for Oil & Lubrication Tanks

The WKC1204-L99 is a fully submersible capacitive level sensor engineered for oil tanks, automated lubrication systems, and high-viscosity liquid monitoring. Unlike traditional float-based switches, it features no mechanical moving parts — eliminating clogging, jamming, and false alarms caused by viscous grease or adhesives.

Built with a 316L stainless steel housing and a food-grade PEEK conical probe, it achieves IP68 protection for long-term immersion in oil or water. The integrated LED status indicator and quick-connect aviation plug simplify on-site commissioning and maintenance.

• Extended M12 Stainless Steel Threaded Housing

  Extended threaded section accommodates thick-walled oil cans and lubricant tanks, with adjustable installation depth; made of 316 stainless steel for oil resistance and anti-rust properties, IP68 fully waterproof, capable of long-term operation fully submerged in oil or grease.

• Conical Food-Grade PEEK Probe

  Tapered conical surface prevents oil and viscous lubricants from sticking; grease, hydraulic oil, and lubricants slide off automatically after contact, minimizing material buildup and false alarms.

• Integrated Status Indicator Light

  Housing features a built-in green LED indicator for clear visual monitoring of detection status, eliminating the need for external instruments during on-site commissioning.

• Orange Oil-Resistant M12 Quick-Connect Aviation Connector

  Oil-resistant and anti-aging cable with quick plug-and-unplug connector, enabling convenient equipment disassembly and maintenance—distinct from standard direct-wire models.

• Capacitive Sensor with No Mechanical Components

  No float or spring mechanism, preventing clogging or jamming by viscous grease; specifically designed for oil level monitoring in lubrication systems, also suitable for detecting adhesives, sauces, clean water, and electrolytes.

• Automated Lubrication Systems: Grease lubricator, hydraulic oil tank, and grease reservoir level low alarm
• Industrial Dispensing Equipment: Level detection for lubricants, greases, and high-viscosity adhesives in material tanks
• Food Machinery: Limit control for edible oil, sauces, and syrup storage tanks
• General Hydraulic Equipment: Low-level protection for small oil tanks to prevent dry-running of oil pumps
