Fluid Level Indicator (Brake) Sensor that monitors the level of brake fluid in the reservoir. When the fluid level drops below the minimum allowed limit, the circuit closes and can activate a warning light or other signal. Ideal for ensuring that the braking system always has the correct fluid level and to avoid driving with low brake fluid, a requirement in e.g. SFRO builds. Installation: The sensor is mounted in the brake fluid cap or at the top of the reservoir. The built-in float moves with the fluid level and closes the circuit when it reaches the bottom position. Technical specifications: Installation depth in reservoir: 51.5 mm Circuit closes at: 50 mm from the top edge of the reservoir Max material thickness at mounting hole : 8 mm Float diameter: 26 mm
