Coolant Level Sensor Types Product

As a coolant level sensor manufacturer, we are making our contribution to manufacturing coolant level sensor including coolant level switch, radiator coolant level sensor, expansion tank level sensor, coolant reservoir level sensor and coolant tank level sensor.

A coolant level sensor definition is that a device designed to monitor the coolant level in a system. It utilizes various technologies to measure the amount of coolant present and provides accurate feedback to the control system. The sensor is typically integrated into the coolant reservoir or the engine block, depending on the application.
Maintaining the right coolant level is essential for the smooth operation and longevity of engines. The coolant level sensor serves as a vital component in this process, providing real-time information about the coolant level to the vehicle’s or equipment’s control system. By alerting users to low coolant levels, it enables them to take prompt action and avoid potential engine damage.

We will provide our coolant level probe, detection and alarm solutions for your real function requirement. Therefore, if you need coolant level sensor and tank, feel free to ask our coolant level sensor price. Here are the types of the coolant level sensors. Welcome to get a free quote.

Knowledge about Coolant Level Sensor

How does A Coolant Level Sensor Work

Coolant level sensors utilize different technologies depending on the type and application. There are three common types of the coolant level sensor below. 

Float Type Coolant Level Sensors

Float type coolant level sensors are commonly used in automotive applications. They consist of a float connected to a pivoting arm. As the coolant level changes, the float moves, causing the arm to rotate. This rotation activates a switch or a sensor, indicating the coolant level.

Conductivity Type Coolant Level Sensors

Conductivity type coolant level sensors utilize electrical conductivity to determine the coolant level. They feature two electrodes placed at different heights in the coolant reservoir. When the coolant reaches a certain level, it completes the circuit between the electrodes, indicating the presence of coolant.

Optical Coolant Level Sensors

Optical coolant level sensors use light beams to detect the coolant level. They consist of an infrared light emitter and a receiver placed on opposite sides of the coolant reservoir. When the coolant level drops below a certain point, the light beam is interrupted, signaling a low coolant level.
