Product details
Apex FMM Optical Level Sensor OS-1 With Magnetic Mount is a replacement optical level sensor for the Apex Fluid Monitoring Module (FMM). It detects a change from wet to dry (and back again) by using reflected infrared light, then signals your Apex controller when the sensor state changes. In an aquarium setup, this makes it useful for water-level monitoring and alerts, such as a high-level or low-level warning sensor in a sump or water storage area, or as part of a DIY auto-top-off (ATO) approach.
Features:
- Designed to plug into your Apex FMM for fluid-state monitoring
- Detects wet-to-dry and dry-to-wet conditions using reflected infrared light
- Provides a state-change signal to your Apex controller when conditions switch
- Can be mounted into custom brackets for flexible installations
- Can also be mounted through a hole in a vessel or tank component
- Useful for level warnings in a sump or water storage container
- Can be used as part of constructing a custom ATO (auto-top-off) setup
- Included mounting hardware supports secure installation: a fastening nut and silicone washer
