1. Working Principle of Trumsense XKC-Y28-RS485 (  DC 24 V ) Contactless Liquid / Water Sensor or Liquid Detector or Fluid Monitor :

Intelligent non-contact liquid level sensor produced by Shenzhen Trumsense Technology Co.,Ltd. uses the inductive capacitance of water to detect whether there is liquid. When there is no liquid approaching the sensor, due to the presence of distributed capacitance on the sensor, there is a certain static capacitance on the ground of the sensor. When the liquid level slowly rises and approaches the sensor, the parasitic capacitance of the liquid will be coupled to the static capacitance, so that the final capacitance value of the sensor becomes larger, the changed capacitance signal is then input to the control IC for signal conversion, the changed capacitance is converted into a certain amount of change in electrical signal, and then a certain algorithm is used to detect and judge the degree of this change, when this change exceeds a certain threshold value. The capacitance signal is then input to the control IC for signal conversion, and the changed capacitance is converted into a certain amount of change in electrical signal, and then a certain algorithm is used to detect and judge the degree of this change, when this change exceeds a certain threshold value It is considered that the liquid level has reached the sensing point.

2. Brief Introdution of Trumsense XKC-Y28-RS485 (  DC 24 V ) Contactless Liquid / Water Sensor or Liquid Detector or Fluid Monitor :

The intelligent non-contact liquid level sensor (hereinafter referred to as the liquid level sensor) adopts advanced signal processing technology and high-speed signal processing chip, which breaks through the influence of the wall thickness of the container and realizes the true non-contact detection of the liquid level height in the closed container.The liquid level sensor (probe) is installed above and below the outer wall of the container under test (the high and low levels of the liquid level). There is no need to open holes in the non-metallic container, the installation is simple, and the production is not affected.It can realize the detection of various toxic substances, strong acids, strong alkalis and the liquid levels of various liquids in high-pressure airtight containers.The liquid level sensor has no special requirements for the material of the liquid medium and container, and can be widely used.

XKC-Y28-xxx series products are specially developed for liquid level detection in non-metallic pipelines or flat surface water or liquid tank. XKC-Y28- products are specially developed for liquid level detection of non-metallic pipelines (pipeline outer diameter D≥11MM) or flat containers.

This series of liquid level sensors is divided into two signal output interfaces, which are the normally open output of the relay and the normally closed output of the relay and RS485 output:

● Normally open output interface-model: XKC-Y28-NO (5v), (12V), (24V)

4. Application Prerequisites of XKC-Y28-RS485 (  DC 24 V ) Contactless Liquid / Water Sensor or Liquid Detector or Fluid Monitor:

a. Viscosity of measured liquid medium

Dynamic viscosity < 10mPaS normal measurement. 10mPaS < dynamic viscosity < 30mPaS may affect the detection. Dynamic viscosity > 30mPaS due to a large number of liquid attached to the container wall, can not be measured.

b.With the increase of temperature viscosity decreases, most of the high viscosity of the liquid is more affected by temperature, so pay attention to the liquid temperature effect when measuring liquid viscosity.

c. Pay attention to keep the sensor clean, as far as possible to achieve anti-corrosion and avoid other objects violent collision, hit.

d. Outdoor installation should avoid direct sunlight and rain direct flow to the sensor body, and away from the high heat source and pay attention to ventilation, if the ambient temperature exceeds the rated temperature, the corresponding cooling protection measures should be taken.

e. When the ambient temperature is lower than the normal operating temperature range of the sensor, the instrument protection box or other protective rain cap device can be used for antifreeze protection, and pay attention to keep the sensor dry. Sensors should be regularly maintained. ( The detection time interval is determined by the user according to the specific situation ).

5. Application Environment of Trumsense XKC-Y28-RS485 (  DC 24 V ) Contactless Liquid / Water Sensor or Liquid Detector or Fluid Monitor:

1. This product is suitable for pipes with an outer diameter above 11mm.

2. The liquid hose or water container material should be non-metallic one

3. The liquid with hose or tank should has conductivity,because XKC-Y28-Rs485 working principle is capacitive.

※ If your liquid hose or container is metal ,please refer to the below product, which is specially designed for the metal material contaner or hose because its working principle is ultrasonic:
