Sensor Tingkat Air Sensor Tingkat Cairan dengan Xkc-Y25 Alarm Deteksi Cairan

1, Product overview:

The intelligent non-contact liquid level sensor (hereinafter referred to as liquid level sensor) adopts advanced signal processing technology and high-speed signal processing chip, which makes a breakthrough

The influence of the wall thickness of the container is analyzed, and the real non-contact detection of the liquid level in the closed container is realized. The liquid level sensor (probe) is installed on the outer wall of the tested vessel

It is easy to install and does not affect the production. It can be used in high pressure closed container

All kinds of toxic substances, strong acid, strong alkali and all kinds of liquid level detection. The liquid level sensor has no special requirements for the material of liquid medium and nonmetal container

It can be widely used.

Xkc-y25-xxx series products are specially developed for liquid level detection of non-metallic containers. This series of liquid level sensors have four signal output interfaces,

They are high-level and low-level output interface, NPN output interface, PNP output interface and RS485 output interface; the four output modes correspond to the following

Four models:

High and low level output interface model: xkc-y25-v

NPN output interface model: xkc-y25-npn

PNP output interface model: xkc-y25-pnp

RS485 output interface model: xkc-y25-rs485

Liquid, powder and particle can be detected.

6. Open collector electrode output mode, wide voltage range (5-24 V), suitable for connecting various circuits and product applications.

3, Working principle:

The intelligent non-contact liquid level sensor uses the inductive capacitance of water to detect whether there is liquid. When there is no liquid close to the sensor, the sensor will stop working

Because of the distributed capacitance, the inductor has a certain static capacitance to the ground. When the liquid level slowly rises close to the inductor, the parasitic capacitance of the liquid will decrease

 

It will be coupled to the static capacitance to make the capacitance value of the inductor larger, and the changed capacitance signal will be input to the control IC for signal conversion to change the capacitance value

The capacitance is converted into the change of a certain electrical signal, and then a certain algorithm is used to detect and judge the degree of the change, when the change exceeds a certain value

When the threshold value is reached
