The company has become a regular supplier of many small and medium-sized enterprises and a partner of domestic merchants, and strives to become one of the companies in the industry.

Below Dongguan Guanglian introduces the working principle of ENS3116 German HYDAC liquid level sensor:

The working principle of ENS series HYDAC liquid level sensor:

Using the principle of static pressure measurement, when the liquid level transmitter is placed at a certain depth in the liquid to be measured, the pressure formula on the liquid surface of the sensor is: Ρ = ρ .g.H + Po where:

P: pressure on the liquid surface ofthe transmitter

ρ: Measured liquid density

g: Local gravitational acceleration

Po: Atmospheric pressure on the liquid surface

H: The depth of the transmitter in the liquid

At the same time, the pressure of the liquid in the overpressure chamber is brought from the sensor through the gas-conducting stainless steel and then the liquid. The atmospheric pressure Po on the surface is connected to the negative pressure chamber of the sensor to compensate for the Po on the back of the sensor, so that the pressure measured by the sensor is: ρ.g.H. Of course, the depth of the liquid level can be obtained by measuring the pressure P.

Features:

Good stability, long-term stability of full scale and zero position can reach 0.1% FS/year. In the compensation temperature range of 0 ~ 70 ℃, the temperature drift is less than 0.1% FS and less than 0.3% FS in the entire allowable operating temperature range.

With reverse protection and current limit protprotection circuit, the transmitter will not be damaged if the positive and negative poles are reversed during installation, and the transmitter will automatically limit the current within 35MA when abnormal.

Sturdy structure, no moving parts, high reliability, long service life.

Easy installation, simple structure, economical and durable.

The device has 1, 2 or 4 switching outputs and an optional analog output signal. In addition to the conventional min and max switching signals, the variant with 4 switching outputs can also set additional warning signal messages, e.g. to prevent the water tank from overflowing or the pump from sucking in air. The ENS 3000 can be used not only in oil but also in water; select the measurement medium in the application-specific menu item. The main application of the ENS 3000 is mainly in hydraulic systems, for example for flow monitoringdust level of tanks. The ENS 3000 comes standard with rod lengths of 250 mm, 410 mm, 520 mm and 730 mm. The device is available to the user with or without a temperature sensor.

ENS series HYDAC liquid level sensor is a pressure sensor for measuring liquid level. The static pressure drop-in liquid level transmitter (liquid level meter) is based on the principle that the measured liquid static pressure is proportional to the height of the liquid. It uses the latest insulated diffuse silicon sensitive element or ceramic capacitor pressure sensitive sensor to convertthe static pressure It is converted into an electrical signal, and then converted into a standard electrical signal (usually 4-20mA/1-5VDC) after temperature compensation and linearity correction.

The HYDAC liquid level sensor of the ENS series is an electronic liquid level switch with integrated display function. The device has 1, 2 or 4 switching outputs and an optional analog output signal. In addition to the conventional small and large switching signals, the variant with 4 switching outputs can also be programmed with additional warning messages to prevent the tank from overflowing or air being sucked in by the pump, for example. ENS 3000 can do that not only for oil, but also for water: Select the measuring medium in the application-specific menu item. The main application of the ENS 3000 is mainly in hydraulic systems, for example for monitoring the liquid level of storage tanks. The ENS 3000 is standard, with rod lengths of 250 mm, 410mm, 520mm and 730mm. Users can use the device with or without a temperature sensor.
