Oil Quality and Level Sensors

Oil Level and Quality Sensors

Improve asset health state awareness with Poseidon Systems’ Trident™ LH sensor. The Trident™ LH sensor monitors the oil level, quality, and water contamination in real-time. The device promotes conditioned-based maintenance practices, allowing for the earliest indication of lubricant issues and avoiding costly downtime. Investing in the reliability of the LH sensor eliminates the need for daily or periodic oil lubrication checks. You will be able to optimize oil drain and sampling intervals.

Optimize Lubrication Maintenance Practices

Poseidon Systems’ Trident™ LH sensor is easily installed in place of a typical oil level sight glass and comes in both wired (LH2500) and wireless (LH2600) versions. These sensors utilize capacitive measurements to monitor oil level, a dielectric measurement to track overall oil health, and a water activity measurement to monitor for water contamination.

Trident LH2500/LH2600 sensors support all oil types and identify low or high oil levels.
