Industrial weighing
In-motion weighing controller
- Our scope
- Hardware, firmware and software
- Outcome
- Field-deployed in weighbridges and in-line checkweighers, with event-wise readout in the cloud.
Engineering service
Testing and Production Support
Bench and functional testing in our lab, field trials at the installation site, and environmental and certification tests arranged through the test plan. Then BOM, cost and volume-production support.
Is this service a fit?
Typical clients
- Prototypes that need validation before production
- Products that behave differently at customer sites than in the lab
- Designs moving from a few units to volume production
Problems it solves
- Last-minute surprises found only at installation
- No evidence that the product meets its requirement
- Parts that become unavailable during production
- A BOM that costs more than the target
Scope
What’s included
- Functional testing against the agreed requirement, in our lab
- Power-rail verification and communication-interface testing, in our lab
- System integration and testing
- Field trials at the installation site
- Environmental testing, with the test location agreed in the test plan
- Units and documentation prepared for certification tests at an external laboratory
- BOM design and cost optimisation
- Support for volume production
Production support
Component selection, BOM design, cost optimisation and support for volume production are part of this service. We prepare the release package (Gerber, NC drill, stack-up, pick-and-place and assembly drawings) and support the first production run.
What we need from you
- Requirement or acceptance criteria
- Prototypes or samples
- Schematics and firmware version
- Expected installation environment
- Production volume and target cost
- Manufacturing partner details, if any
What you receive
- Test plan
- Bring-up summary and action tracking
- Validation report with logged observations
- Field-trial observations
- BOM with cost notes
- Manufacturing release: Gerber, NC drill, pick-and-place and assembly drawings
- Support for the first production run
The exact list, file formats and ownership are confirmed in your project proposal.
At a glance
Where each test happens
Field trials take place at a real site, not in the lab. We are not a test laboratory: certificates and accredited reports come from the external laboratory.
| Where | What is tested | Notes |
|---|---|---|
| In our lab | Board bring-up, functional tests against the requirement, power-rail checks and communication-interface tests | Oscilloscopes, logic analysers, signal generators, power supplies, programmers and JTAG/SWD debuggers; spectrum analyser and VNA support where required |
| At the installation site | Field trials of prototypes or pilot units with the real supply, wiring and network coverage | Sites, dates and who attends are agreed with you |
| At an external laboratory | Certification and compliance tests that need an accredited laboratory, and environmental tests that the test plan places there | The laboratory is chosen with you and issues the report; we do not certify products |

From our engineering notes
What to send with a first engineering enquiry
The short list Sai Agro Tel asks for before a first reply: what the device must do, where it will be used, the stage, and the quantity.
What a six-layer weighing board had to include
Four boards, a six-layer LPC1788 controller, RTOS firmware and cloud readout for weighbridges and in-line checkweighers.

FAQs
Frequently asked questions
Can’t find your answer? Ask the team directly.
What test equipment do you have?
Oscilloscopes, logic analysers, signal generators, power supplies, programmers and JTAG/SWD debuggers, with spectrum analyser and VNA support where required.
Can you certify our product?
No. Certification and compliance tests are done by an external laboratory, which issues the report. We can prepare units and documentation for those tests when that is in scope.
Do you support production?
Yes. BOM design, cost optimisation and support for volume production are part of this service.
Where is your factory?
F-35, Basweshwar Complex, Vishweshwar Chowk, PCNTDA, MIDC, Bhosari, Pune 411026.
