Measure temperature before the furnace in a smart factory
Smart factories don't start with software; they start with a repeatable measurement across every shift.
When the foundry goes digital, most data moves to the system: output, scrap, energy consumption, and order progress. However, pre-furnace temperature often remains on paper because the measuring device is standalone and not connected.
This is the missing link that has kept root cause analysis of scrap at the level of speculation. The article outlines how to collect temperature data across investment levels, from structured manual entry to direct integration.
Key Control Points
Level 1: Handwritten with template
Standardize the number of batches, time, temperature, and measurer; this is a zero-cost step that produces usable data.
Level 2: saved on device
Select a device with result memory that exports data by shift to the computer.
Level 3: system connection
Use communication port devices to input data into the production management software.
Required conditions
Regardless of the level, each number must be linked to a batch, furnace, and detail code; otherwise, the data cannot be used for analysis.
Real-world experience
- Select a pilot production line before scaling to the full factory.
- Establish naming conventions for batch numbers and furnace codes from the start.
- Monitor data for the first few weeks, as entry errors are the most common reason digital projects stall.

Frequently Asked Questions
Do small factories need to digitize right away?
No need. Start with the unified entry form; once data is stable, consider connected devices.
Does the measuring device have a communication port?
Varies by model and configuration; confirmation required at order. Some models include RS485 ports upon request.
