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. - 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.
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. This optical water level sensor is easy mounting and can be used in impure or adhesive liquid.
