❓ Frequently Asked Questions (FAQ)
Q1: What type of liquid can FS-SDOL-0448 detect?
A1: The sensor works with both transparent and opaque liquids, including water, saline, and most organic fluids, as long as they are not corrosive to the sensor housing.
Q2: Is the sensor affected by ambient light?
A2: No, it is designed to resist high ambient light up to 100 kLux, ensuring accurate detection even in bright environments.
Q3: Does the FS-SDOL-0448 require calibration?
A3: No calibration is needed. It is factory-calibrated and ready for direct integration upon installation.
Q4: Can this sensor detect the level of viscous fluids?
A4: Yes, it can detect viscous fluids as long as the fluid can make optical contact with the sensing surface.
Q5: What is the typical lifespan of the sensor?
A5: The solid-state design ensures a long lifespan, typically exceeding 10 million cycles under normal operating conditions.
Q6: Is the sensor compatible with microcontrollers?
A6: Yes, the digital output makes it easy to interface with microcontrollers, PLCs, or digital I/O modules.
Q7: What is the correct mounting orientation?
A7: The sensor can be mounted in any orientation, but vertical mounting is recommended for optimal fluid detection.
