Why you need this sensor Prevents unnoticed low oil or water levels by providing a clear visual alarm when the set threshold is reached. Reduces risk of damage or service interruptions on vehicles and equipment that rely on proper fluid levels. Simplifies maintenance with a design that is easy to disassemble and clean. Key features and benefits Visible alarm: When the alarm threshold is reached the indicator icon switches to a red backlight, making lowlevel conditions immediately obvious. Clear emptylevel specification: When oil or water level is empty, the float leaves a gap of 3–15 mm between the sensor float and the bottom of the sensor — a defined tolerance that supports consistent lowlevel detection. Wide compatibility: Designed for use in Marine Boats, Trucks, Buses, Motor Homes, Hot Rods, and Generators. Easy maintenance: The unit is simple to disassemble and clean, allowing fast servicing and reducing downtime. How it solves common problems Detects low fluid levels visually so you can act before pumps run dry or engines overheat. Fits a broad range of vehicles and equipment so you can use the same type of sensor across multiple assets. Simple cleaning reduces the risk of false readings caused by debris or buildup. Practical use scenarios Marine boat: Monitor bilge or fuel tanks so the red backlight alerts crew to refill or address a leak before engine damage occurs. Generator: Keep an eye on oil levels during extended operation; the red alarm alerts operators to add oil before performance is affected. Commercial vehicle: Install in trucks or buses to provide drivers and technicians with a straightforward visual warning of low fluid levels. What to expect Reliable visual indication at the configured threshold (red backlight). A clearly defined emptylevel gap of 3–15 mm between float and sensor bottom. Straightforward disassembly for routine cleaning and inspection. Compatibility and use Suitable for Marine Boats, Truck, Bus, Motor Home, Hot Rod, and Generator installations. Follow your vehicle or equipment guidelines for mounting and threshold settings. Easy upkeep Disassemble for cleaning without special tools, helping maintain correct operation and extend service intervals.
