Product Description

product presentation

The weighing module is a standardized component integrating high-precision sensors, mechanical load-bearing structures, and signal processing units. It is specially designed for industrial scenarios and can be directly integrated into equipment such as material tanks, reactors, conveyor lines, and suspended hoppers to achieve weight monitoring and data feedback.
 
Its core features are: compatible with multiple installation methods (fixed/suspended/floating), without the need to modify the equipment body; It features anti-interference, resistance to high and low temperatures, and anti-corrosion (with protection grades mostly IP67/IP68), making it suitable for harsh working conditions such as dampness, dust, and chemical industries. It supports integration with PLC and cloud systems, outperforming precise weighing data (with an accuracy of up to OIML III grade), and is widely used in industrial batching, inventory measurement, trade settlement and other scenarios. It is a cost-effective solution for realizing the weighing function of equipment.

Product Advantage

1.Flexible installation:

Compatible with various equipment such as material tanks and reaction vessels, supports fixed, suspended and mobile installation, no need for large-scale modification of existing equipment, and occupies a small space.
 
2. Stable precision:

Strong resistance to vibration and electromagnetic interference, capable of compensating for equipment displacement and off-center load, with small long-term zero drift, meeting the requirements of industrial-grade weighing.
 
3. Environmental durability:

High protection grade (IP67/IP68), resistant to acids, alkalis, high and low temperatures, and capable of withstanding harsh working conditions such as moisture, dust, and impact.
 
4. Controllable cost:

The purchase price is lower than that of dedicated weighing equipment. No complex foundation is required for installation. Maintenance is convenient and the cost is low, offering high cost performance.
 
5. Expandable intelligence:

 Supports interfaces such as RS485/4G, can be connected to PLC and cloud systems, and is suitable for the requirements of the Internet of Things and secondary development.
 
6. Safety and Compliance:

 Some parts come with explosion-proof certification (ATEX/IECEx), comply with metrology and food-grade standards, have built-in overload protection, and are compatible with special industry regulations.

Maintenance and Care Methods

Maintenance Category	Specific Operations	Cycle	Core Objective
Daily Inspection	1. Wipe the module surface to remove dust, residues and standing water; 2. Check for no rust or deformation on the appearance; 3. Verify if the zero point is stable	Once a day	Eliminate surface hazards promptly and ensure basic functionality
Connection Tightening	1. Check bolts connecting the module to equipment and between the sensor and junction box to prevent loosening; 2. Inspect cable connectors for no oxidation and good contact	Once a week	Avoid uneven force or signal fluctuation
Core Component Maintenance	1. Clean the junction box and check for moisture/dust; 2. Test the sensor's anti-interference performance; 3. Lubricate the guide rods of floating modules	Once a month	Ensure the performance of electrical and mechanical components
Environmental Protection	1. Corrosive environments: Apply anti-rust/anti-corrosion agents; 2. Humid/outdoor environments: Check waterproof sealing; 3. Vibrating environments: Reinforce shock absorption	Once a quarter	Adapt to harsh working conditions and extend service life
Accuracy Calibration	1. Calibrate with standard weights in the range of 20%-100% of the full scale; 2. Calibrate immediately when abnormalities (impact/deviation) occur	Once every 3-6 months	Maintain weighing accuracy and meet metrological requirements
Operation Avoidance	1. Prohibit overloading (≤120% of the full scale); 2. Cut off power before maintenance to avoid cable pulling; 3. Do not rinse the junction box with a high-pressure water gun	Long-term implementation	Reduce man-made damage and lower failure rates

FAQ

Q1:Will weighing modules be damaged if overloaded? How to prevent overloading?
A1: Short-term slight overloading (≤120% of the rated capacity) usually does not cause immediate damage (most modules have overload protection), but long-term/severe overloading (>150% of the rated capacity) can lead to permanent deformation of the sensor and direct damage. 
Prevention methods:
Set up "overload alarms" in the system (e.g., trigger an audible and visual alarm and cut off material feeding when the load reaches 110% of the rated capacity);
Install buffer devices (e.g., chutes, buffer pads) during material feeding to avoid direct impact of materials on the module;
Reserve 10%-20% of the rated capacity during selection (e.g., choose a 600kg capacity module for an actual maximum load of 500kg).

Q2:Can weighing modules be connected to IoT systems?
A2: Yes. Modules with communication interfaces should be selected:
Wired: Support RS485 (Modbus-RTU protocol) for connection to PLC and DCS systems;
Wireless: Support 4G/Wi-Fi for direct data upload to cloud platforms (e.g., MES systems, mobile apps), enabling remote monitoring of weight changes and report generation to meet industrial digitalization needs.

Q3:What should be noted when choosing weighing modules for explosive environments?
A3::Focus on 2 core points to avoid safety risks:
Explosion-proof certification: Modules must have certification suitable for the specific scenario (e.g., Ex d IIB T4 Ga flameproof type for chemical gas environments, Ex tD A21 IP65 for dust environments). The certification must comply with local standards ( ATEX/IECEx internationally);
Installation specifications: Use explosion-proof cable glands and sealed connectors for cables to prevent spark generation; the module must be grounded when connected to equipment (ground resistance ≤4Ω) to prevent static accumulation.
