SmarTrack Data Logger: How Our Thermal Profiling System Has Evolved

If you’ve been profiling furnaces, ovens or heat-treatment lines with a SmarTrack data logger for a while, you already know why thermal profiling matters — you can’t control what you can’t measure inside a closed, hot process. What’s changed recently is how well the logger measures it. After several rounds of field feedback and product development, the SmarTrack data logger and software have moved on quite a bit from the original SmarTrack 10. This post walks through what’s different, and why it matters if you’re validating heat-treatment cycles, running TUS surveys, or just trying to get a clean furnace profile without babysitting the equipment. Over the last couple of development cycles, we made a lot of changes to the logger and the software around it. Some were small. A few change how you’d actually plan a furnace temperature profiling job. This post explains what’s different, in plain terms, without turning it into a spec sheet you have to decode.

Why Thermal Profiling Matters in the First Place

A thermal profile tells you three things about a process: what temperature was reached, how long the product stayed there, and where in the furnace or oven that happened. It’s used across soldering and reflow, heat treatment, glass and ceramic manufacturing, food processing, and paint curing — anywhere product quality depends on a temperature curve rather than a single reading. The logger travels through the process (shielded by a thermal barrier box), records continuously, and the data gets pulled apart afterward in software to confirm the process did what it was supposed to.

The logger and the software are really one system. If either one falls short, you either lose confidence in the data or you lose time re-running the process. That’s the part we focused on improving.

What Changed in the Data Logger

The table below lines up the original SmarTrack 10 (as documented in our earlier catalogue) against the current SmarTrack 10/20 series.

A few of these are worth calling out specifically, since they change how you’d actually use the logger day to day.

Memory stopped being a limiting factor. 50,000 readings per channel overall 5 lakh readings sounds like a lot until you’re running a slow, long-duration profile — a kiln car cycle or an aging furnace run — at a tight sampling interval. The jump to 40 lakh total readings means you’re far less likely to plan a profile around memory constraints rather than process requirements.

Thermocouple flexibility widened considerably. The original model was built around Type K with other types available on order. The current version natively supports nine thermocouple types plus mixed combinations in a single run, which matters if you’re profiling a process with widely different zone temperatures — say, a low-temperature preheat zone and a high-temperature soak zone in the same furnace pass.

One platform, two temperature ratings. 70°C rating (NiMH battery, rechargeable, 20 days of battery life) or a 100°C rating (lithium battery, non-rechargeable, 40 days). You can stretch that further with the logger’s built-in sleep mode, which lowers the scanning rate between readings when you don’t need continuous fast sampling — useful on long, slow runs where you’d rather not carry a spare battery. The barrier box gets matched to whichever rating you pick — dry insulation or PCM-based for 70°C, evaporative-based for 100°C. It’s the same logger family either way, just configured for the job at the time of order.

Battery replacement is also simpler than it used to be. The battery pack sits in a tool-free compartment, so swapping it is about as involved as changing the batteries in a toy.

What Changed in the Software

Software is where a lot of the actual analysis work happens, and this is the area that changed the most.

The older SmarTrack 10 software covered the basics well — multi-channel comparison, Excel export, one-page PDF/Excel/Word reports, offset handling. What it didn’t have was live monitoring, tolerance band analysis, slope calculation, or a dedicated TUS (Thermal Uniformity Survey) workflow. The current Advanced plan adds all of that, along with audit-ready report formatting those lines up with AMS2750 and CQI-9 documentation practices. Worth noting: the software supports the documentation side of these standards — actual certification still sits with your quality system and auditor.

For teams doing routine furnace checks and basic validation, the Basic plan still covers that ground without extra cost. The Advanced plan earns its place when you’re doing TUS surveys, heat-treatment validation, or need reports that go straight into an audit file without manual reformatting.

Should You Upgrade?

If you’re running an older SmarTrack 10 today, the honest answer depends on what’s limiting you. If memory constraints are forcing you to shorten profiles or reduce sampling resolution, or if you’re manually calculating tolerance bands and slopes in a spreadsheet after every run, the newer logger and Advanced software will save real time. If your current setup already covers routine checks comfortably, there’s no urgency — the Basic plan and standard logger still handle that work reliably.

For anything involving audit documentation, TUS surveys, or high-temperature long-duration profiling, the current SmarTrack series and Advanced software are a meaningful step up from the original.

FAQ

What is a thermal profile check?
A thermal profile maps the time-temperature relationship of a product moving through a heating system. Tempsens equipment records and displays this data to help validate and optimise your heating process.

How is a thermograph used to measure temperature?
A thermograph simultaneously captures continuous temperature readings from multiple thermocouple sensors. The SmarTrack 10 Data Logger stores this timestamped data, which is then analysed to generate a complete thermal profile.

How are thermocouples used to measure temperature?
Thermocouples produce a voltage proportional to the temperature difference between two junctions. The SmarTrack 10 converts this voltage into precise temperature readings at 0.1°C resolution, within the thermocouple’s specified range.
