Photoelectric Liquid Level Sensor, Stainless Steel, PNP/ NPN

Photoelectric Liquid Level Sensor, Stainless Steel, PNP/ NPN

Stainless steel photoelectric level sensor, 1/4 NPT thread type, is NPN/ PNP signal output directly driving the relay. It is a kind of liquid level controller which detects with infrared ray to avoid inducting wrong action by interference of sun or light. The optical water level sensor is easy mounting and can be used in impure or adhesive liquid. The maximum current consumption of the liquid level sensor is less than 15mA, with low power consumption and fast response.

Overview

Photoelectric liquid level sensor can be widely applied in water purification, sewage treatment, electrical industry, hydraulic machinery and so on. It provides protection of antipole, overvoltage, short circuit and transient. This optical liquid level sensor has the functions of lack of liquid reminder and full liquid overflow prevention to ensure the safe operation of the equipment.

Applications of Photoelectric Liquid Level Sensor

Tips: What are the advantages of photoelectric liquid level sensor?

Accurate liquid level detection, high repeatability and fast response.
The output of liquid level is only related to whether the photoelectric probe contacts the liquid level, and has nothing to do with other characteristics of the medium, including temperature, pressure, density and electrical parameters, so the detection of the photoelectric liquid level switch is high accurate and repeatable.
It can be made into multi-point liquid level sensor.
Because the volume of photoelectric probe is relatively small, multiple photoelectric probes can be installed on a measuring body to make multi-point liquid level sensor and controller.
Strong adaptability to the environment.
Photoelectric level switch can be used in vacuum and pressure environment, flammable and explosive occasions, as well as special liquid environment such as turbulence, bubble, vibration and steam, etc., or used in combination with other sensors (such as pressure sensors, etc.).
It is suitable for special container installation.
The photoelectric probe can be installed separately in a small space and is suitable for special tank or container.
