Dinghua Electronics innovates liquid level measurement case to assist in safe and efficient production

Energy gathering type external liquid level gauge:

By adopting the energy gathering steering technology, the signal strength is increased by 20-50 times, successfully solving the signal attenuation problem caused by the self aggregation deposition of vinyl chloride tanks.

For example, in the VCM single storage tank of Wuhai Junzheng, the product increases the echo signal from 200mV to 10V, reduces the blind spot to 1/10 of traditional level gauges, and achieves continuous and stable measurement.

SA Gpro external liquid level switch:

The SA Gpro external liquid level switch has attracted the attention of many attendees with its design and excellent performance.

In terms of structural design:

The integrated structure is matched with the whole machine inspection before leaving the factory, reducing the number of connecting parts, avoiding rainwater hazards, and improving product reliability.

In terms of performance:

With the technology and algorithm of "micro vibration analysis" and "variable frequency ultrasonic", it can effectively cope with complex working conditions.

During the debugging process:

Simple human-machine interface combined with Bluetooth wireless connection and cloud technology support, easy to operate, even non professionals can easily get started.

The all-new T25 Ultra probe

Innovative self matching magnetic suction technology, with a probe vertical tension of over 800N, horizontal resistance of over 200N, and a stability improvement of 33%.

The front-end dual sealing structure can withstand a water pressure of 10kPa, and the back-end interface has an IP67 protection level, solving the problem of coupling failure.

Intelligent electro-hydraulic actuator: restructuring industrial valve control

At the exhibition site, the DHE-EH series intelligent electro-hydraulic actuator launched by Dinghua Electronics became the focus.

DHE-EH series intelligent electro-hydraulic actuator

The DHE-EH series intelligent electro-hydraulic actuator is a new type of actuator mainly used for valve opening/closing or opening degree adjustment. It can input/output analog signals (4-20mA), opening/closing signals (dry contacts), etc., and achieve linear or angular displacement through servo control system, high-precision displacement sensor, and hydraulic actuator. It has the characteristics of integrated structure, high adjustment accuracy, adjustable segmented speed, multiple fault safety, and easy operation.

The DHE-EH series electro-hydraulic actuator can be matched with various valves such as disc valves, ball valves, plug valves, air doors, gate valves, globe valves, etc., and is suitable for many fields such as power, metallurgy, petrochemicals, pipelines, ships, docks, urban water treatment, industrial equipment, etc.

Core strengths

Integrated structure:

Integrated structural design, with built-in power and oil source, built-in oil circuit, no risk of oil leakage, and easy installation.

■ Servo control system:

The pump control principle adopts a servo motor to directly switch the oil circuit forward and backward, with a compact structure, fast response, high accuracy, and low noise.

Multiple fault safety:

Control shutdown under normal conditions (DCS system); Control rapid shutdown in emergency situations (SIS system); Electromagnetic valve (power-off type) automatically and quickly shuts off; Automatic action and rapid shut-off of fire relief valve, etc

Segmented speed control:

Multi level speed setting, stable and efficient operation, effectively reducing water hammer effect and protecting valves.

■ No opening operation:

Parameter setting and debugging can be completed through magnetic induction or infrared remote control, without the need to open the cover, making it easy to use.

■ User friendly interface:

High brightness and low-temperature resistant OLED screen, suitable for various climates, displaying real-time information such as opening, pressure, temperature, and fault prompts.

Functional safety:

Produced according to the IEC61508 standard, reaching SIL3 level to enhance safety.

Diagnostic protection:

Equipped with fault diagnosis function, it can achieve temperature protection, locked rotor protection, stall protection, pressure protection, over torque/thrust and limit protection, etc.

Main application scenarios

This product has been successfully applied to emergency shut-off valves and control scenarios in tank farms of multiple enterprises, providing users with a full chain solution from "safety, intelligence, cost reduction" to "efficiency improvement".

DHE-FL series ultrasonic flowmeter

Gas ultrasonic flowmeter is mainly used to measure the volumetric flow rate under working conditions, and then obtain the standard volumetric flow rate based on the temperature and pressure values under working conditions. It has a wide measurement range and high measurement accuracy, and can be applied to flow velocity measurement of various gas media such as natural gas, coalbed methane, ethylene, etc.

The DHE-FL-GP segmental gas ultrasonic flowmeter can be applied to the distribution of urban gas pipelines and trade measurement of urban gas under low pressure conditions for end-users. It can also be used for process measurement in other industrial control and fields. At the same time, it can replace traditional mechanical flowmeters, reduce the maintenance cost of flowmeter products, improve the operational management efficiency of gas enterprises, and promote the new development of the metering industry in the urban gas field.

At this exhibition, in the wave of industrial automation, "safety" and "reliability" are eternal topics for Dinghua. Nowadays, Dinghua Electronics is using innovative technology to provide a brand new answer.

At the conference, Dinghua Electronics made a stunning appearance with multiple "hardcore" products, including energy gathering external liquid level gauges, integrated external liquid level switches, new generation liquid level probes, intelligent electro-hydraulic actuators, and ultrasonic flow meters. These products, with their common genes of "zero leakage and high reliability," outline a smarter and safer industrial future for on-site experts and customers.

The display of Dinghua Electronics not only received high recognition, but also clearly pointed out a new path for industry upgrading: choosing innovation is choosing the future.

In the future, Dinghua Electronics will continue to use innovation as the engine, deeply cultivate core technologies in level measurement and intelligent execution, and drive industrial automation to a higher level. We are committed to empowering enterprises with smarter solutions to transition from "equipment automation" to "management intelligence", contributing Dinghua's wisdom and strength to building a better industrial digital future.
