Frequently Asked Questions
Q: What sizes does this stainless steel float switch come in?
A: This float switch is available in four sizes: 65 mm, 100 mm, 150 mm, and 200 mm. Select the size that best matches your tank or reservoir dimensions and installation requirements.
Q: Can this float switch be installed at the top or bottom of a tank?
A: Yes! The vertical mounting design allows installation at either the top or the base of your tank. Mount it at the top to detect liquid rising to a set level, or at the bottom to detect when the liquid falls below a minimum threshold.
Q: Is this float switch suitable for outdoor or extreme-temperature environments?
A: Absolutely. The stainless steel construction resists corrosion, and the switch operates across a wide temperature range of -30°C to +125°C, making it well-suited for both indoor and outdoor applications, including harsh industrial or chemical environments.
Q: Does this water level sensor require any external power source or battery?
A: No battery is required. The float switch operates on a simple mechanical principle — as the liquid level changes, the float rises or falls, opening or closing the circuit. This straightforward design requires no complex electronics or dedicated power supply.
