Liquid Level Control Display Box: Integrated Solution for Real-Time Industrial Level Monitoring and Sound-Light Alarm
Product Overview
The Nexisense liquid level control display box is an intelligent control terminal specially designed for industrial field level monitoring. It integrates real-time level display, sound-light alarm and automatic water level control functions into one unit. It can be directly used with various level transmitters (submersible, capacitive, differential pressure, etc.), providing a concise and efficient level monitoring solution for engineering projects.
Core Functions and Features
Real-time Display: High-brightness LED digital tube displays the current level value (PV), while the intuitive level bar graph shows the level height change in real time.
Sound-Light Alarm: High and low level alarms are set independently, equipped with red warning lights and buzzers for double reminder.
Water Level Control: Can output switch signals to directly control water pump start/stop or solenoid valves, realizing automatic water replenishment/drainage.
Convenient Operation: Panel buttons support upper/lower limit setting, alarm delay adjustment and manual/automatic mode switching.
Signal Compatibility: Standard 4-20mA input, supports 24VDC power supply, with strong anti-interference capability.
Rugged Structure: Industrial-grade housing with high protection rating, suitable for wall-mounted or cabinet installation.
Good Expandability: RS485 communication interface can be added according to requirements to realize remote monitoring.
The product has no complex programming. It can be put into use quickly after installation, greatly reducing system integration difficulty and debugging time.
Typical Application Scenarios
Water Treatment and Environmental Protection: Level monitoring and automatic control in sewage treatment tanks and clean water tanks.
Municipal Engineering: Water level management in fire water tanks, storage tanks and high-level water tanks.
Petrochemical Industry: Storage tank level monitoring and high/low level alarms.
Power Industry: Level control in boiler feedwater tanks and cooling tower water ponds.
Agriculture and Aquaculture: Automatic level control systems for water towers, wells and fish ponds.
System Integration Projects: As a supporting terminal for level transmitters, linked with PLC, DCS or IoT platforms.
This display control box is particularly suitable for medium and small engineering projects that require local intuitive display and local sound-light alarms, while also requiring simple automatic control.
Selection Guide and Installation Precautions
Selection Points:
Confirm the input type (standard 4-20mA) according to the output signal of the level transmitter.
For projects requiring remote communication, choose the version with RS485 interface.
When the on-site environment is harsh, it is recommended to use a housing with higher protection rating.
For batch engineering projects, contact Nexisense for OEM customization, including panel layout, alarm logic and communication protocol adaptation.
Installation Precautions:
The display box should be installed in a position that is easy to observe and operate, avoiding strong vibration and high-temperature environments.
Use shielded cables for signal lines and ensure good grounding to reduce interference.
When wiring alarm outputs, pay attention to load capacity and avoid directly driving high-power equipment.
After initial power-on, set the high and low alarm values and control logic according to the actual level range.
Regularly check the tightness of wiring terminals and the clarity of the display screen.
Nexisense supports OEM/ODM customization and bulk supply of liquid level control display boxes, and can provide personalized development services according to the control logic, on-site installation methods and system requirements of engineering companies.
