This level controller with a 3-wire connection can be used in the water of ponds, swimming pools and spas.
It is not suitable for measuring the level in a chemical tank (pH dosing liquid, liquid chlorine, etc.). For this, we offer level indicators in a tube filled with protective resin.
The dimensions of the level switch are 55 x 22 mm, the contact is “normally open”, but the signal can be reversed by releasing the float and turning it 180°. Maximum operating temperature: 85 °C.
This switch is usually used to integrate a skimmer, buffer tank, etc.
Manufacturer specifications
The FS-IR02 single-point water level sensor operates on infrared technology and can fully replace the traditional float switch. The sensor controls the liquid level using a high or low voltage.
When the measured level is in air, reflection from the prism allows most of the light to reach the receiver LED, causing the optical level sensor to output a high voltage.
When the measured level is in water, refraction of the liquid allows less light to reach the receiver LED, causing the optical level sensor to output a low voltage.
