A liquid level sensor is a proportional sensor used to convert the water level parameter at a measured point into a corresponding electrical signal in real time. They are broadly classified into on/off type, resistance type, and voltage type.

Features of high-precision range liquid level sensors: Compared to older liquid level switches, the main advantages of range liquid level sensors are: precise matching for use in automated control programs; greater energy efficiency and environmental friendliness; lower energy consumption; and higher safety.

1. 5V voltage input, low-voltage operation eliminates the risk of electric shock, and installation is convenient.

2. Segmented feedback voltage percentage display (1/5-5/5) provides real-time reminders to the driver whether the liquid level needs replenishment.

3. Applicable to various media liquids (antifreeze, oil, etc.).

4. Applicable to various expansion tanks, fuel tanks, and new energy product industries (various new energy vehicles and new energy storage products, passenger and freight vehicles, various types of construction machinery, ships, etc.).

Normally open level switches are primarily used for monitoring and alarming low liquid levels in containers, providing real-time feedback on the container's liquid level percentage. They feature fast response, high sensitivity, and easy installation, making them suitable for expansion tanks of various sizes and models. They are widely used in the automotive, marine, new energy storage, and engineering vehicle industries.
