Key points for selection
Focus on checking the 205×76×40mm, five-hole four-wire, and compatibility with existing weighing indicators or sensors.
Product overview
MV-WA0004 is a stainless steel weighing junction box. The page is organized based on this single product information page and is used for procurement preliminary selection, replacement verification and project interface confirmation. Product type: Stainless steel weighing junction box; overall dimensions: 205×76×40mm; structure: 304 stainless steel shell, signal adjustment; five holes and four wires for wiring.
Applicable scenarios and purchasing value
It is used to adjust the convergence and angle difference of multiple analog load cells, and is suitable for platform scales, hopper scales and multi-support weighing systems. The shell material, number of connections, and excitation or signal adjustment methods must be consistent with the system.
This page is organized according to a single product. The parameters and pictures are from the corresponding information page of the product and are not spliced with other models. Items with unclear information will be marked as order confirmation items.

Selection steps
- First determine the purpose of the attachment in the system
- Check the number of interfaces, wiring or communication protocols
- Confirm the overall dimensions, openings and installation space
- Confirm material, shielding, explosion-proof or environmental requirements
- Confirm compatibility with target instrument or sensor
Installation and commissioning suggestions
- Construction according to wiring diagram and retain wire numbers
- Keep signal lines away from power cables and inverters
- The printer and large screen must first complete the protocol joint commissioning.
- Increase rain protection, grounding and surge measures for outdoor equipment
FAQ
What problems does MV-WA0004 mainly solve?
It is a stainless steel weighing junction box, used for the convergence and angle difference adjustment of multiple analog load cells, and is suitable for platform scales, hopper scales and multi-support weighing systems. The shell material, number of connections, and excitation or signal adjustment methods must be consistent with the system.
Can I replace it only by appearance size?
No. Also check the interfaces, number of connections, adjustment methods, materials, mounting cutouts and supporting instrumentation protocols.
Do accessories need to be consistent with the instrument brand?
Not necessarily, but the electrical interface, communication or printing protocol, wiring definition and power supply must be compatible, and key functions should be jointly tested and confirmed before placing an order.
What is the difference between adjusting the excitation and adjusting the signal in the junction box?
Both methods are used to adjust the fulcrum angle difference, but the circuit methods are different and should be matched with the sensor and on-site maintenance habits, and cannot be selected based on the shell alone.
Why does the weighing signal line emphasize shielding?
The load cell output is usually a low-level millivolt signal. Frequency converters, motors and power cables may introduce interference. Shielding and proper grounding can help with stability.
How to check printer compatibility?
Check the serial port or other interface, baud rate, printing protocol, paper specifications, installation space and power supply. It is best to jointly debug with the target instrument before leaving the factory.
Is bigger screen size better?
It should be selected according to the observation distance, ambient brightness, installation height, viewing angle and communication distance. If it is too large, it may increase the installation and power supply costs.
What should you pay attention to when using it outdoors?
When the protection level is not specified in the data, rainproof boxes, sunshades, sealed joints and reliable grounding should be added, and the temperature and humidity range should be confirmed.
How to check and accept after installation?
Check wiring and fixing, verify zero point, loading, communication, display or print results, and keep interface parameters and wiring records.
What is needed for the request for quotations?
In addition to the purpose, please provide supporting instruments, interfaces, installation dimensions, cable length, environment and quantity. The verified product information on this page includes: product type stainless steel weighing junction box; overall dimensions 205×76×40mm; structure 304 stainless steel shell, signal modulation; wiring with five holes and four wires.
Ordering instructions
When ordering, please indicate the supporting instruments or sensors, interface/wiring method, size, cable length, printing paper or display specifications, installation environment and quantity; if there are explosion-proof requirements, the applicable scope must be confirmed separately.
