Description
TMC100: USB Adapter for Thermocouple, compact and easy to use.
The TMC100, part of the TMC series, is a compact, easy-to-use USB adapter for thermocouples. It allows you to connect a thermocouple to a computer, enabling temperature recording to start in just a few minutes. Compatible with Type K/J/T/N/E thermocouples with 2 or 3 pins, it offers exceptional precision over a wide operating range. The built-in cold junction and thermocouple compensation based on the NIST ITS-90 tables ensure precise and reliable measurements. This lightweight and compact device, with ABS plastic housing, operates on USB power and USB 2.0 communication, offering a convenient and efficient solution for temperature data acquisition with thermocouples.
Like all Dracal measurement instruments, the TMC100 is compatible with free software tools, making it an essential component of a DAQ solution. For those who wish to integrate the TMC100 into their system, there are two options available: command line tools and VCP mode. If you prefer a graphical interface, DracalView is the appropriate choice.

Do you have STEP/CAD files of your instruments?
You can find them on each instrument page under the Datasheets tab if available.
Are your sensors battery-powered?
No, they are not. They are powered via the USB plug; therefore, they must be plugged in to transmit data.
What calibration is performed on the TMC adapter during production?
TMC100: The temperature conversion principles for thermocouples are applied as is. No additional compensation is performed. The accuracy still meets thermocouple standards.
TMC200: Calibration at 0°C is performed to compensate for zero error and improve accuracy.
How do I connect my thermocouple to the adapter?
A two-pin connector is provided with the adapter. Simply open it and plug in the wires of your thermocouple. Then, insert the connector into the USB adapter, and you’re good to go! Removing the connector from the adapter is also challenging, making the construction very robust.
Is an external probe necessary for calibrating the adapter?
No, having a probe to calibrate the adapter is unnecessary. Without a probe, the laboratory will use an instrument that simulates the presence of a theoretical probe. However, if possible, it is preferable to calibrate the device with the final probe to compensate for the probe’s error in calibration and achieve better accuracy.
Is the individual calibration of the measuring instruments done at the Dracal factory
At the Dracal production factory, a pass/fail type of testing is conducted during the production of the measuring instrument. Additionally, the component manufacturer carries out individual calibration at their factory before being shipped to us. These calibrations are not ISO17025 certified, but if your industry does not require this standard, you can confidently use Dracal’s USB adapters upon receiving them.
My temperature probe can be used at more extreme temperatures than the announced housing temperature range (0°C to 50°C). What precautions should I take?
To measure temperature, only the probe should be placed in an environment hotter than 50°C. Additionally, the advertised accuracy for the adapters is optimal at 25°C.
Can I use my own probe with Dracal’s transmitter?
If your probe is compatible with the transmitter, yes! The probes offered by Dracal are just one of a multitude of options.
Are the specifications advertised in the datasheet those of my entire system?
No, they are not. The specifications in the datasheet apply to the transmitter only, with no probe connected. So, for your system (transmitter + probe), you need to “add up” the characteristics not only of the transmitter but also of the probe you choose to connect to it, either the one offered by Dracal or another of your choice.
Why is my transmitter returning data that makes no sense?
If you’ve wired your sensor yourself, you’ve most likely connected the wires to the wrong terminals. Consult the datasheet and check carefully that you’ve followed the connection diagram.
If you disconnected the probe by pulling on the probe wire rather than the connector itself, you may have lost contact between one of the wires and its terminal block. Open the connector and check that all wires are connected.

What are the advantages of choosing a calibratable instrument (-CAL option)?
The devices with the 3-point calibration mechanism have a longer lifetime as it is possible to compensate for the natural drift of the measurements. The cost/lifetime ratio is thus considerably reduced and, just as importantly, this choice is environmental friendly.
These devices can be easily calibrated and certified by external resources (including our ISO17025 certified partner laboratory) and allow you to synchronize your various devices between them.
What are the advantages of using your USB communicating devices over other technologies?
| 1. Connection security. | 6. Continuous power supply. |
| 2. Instant access to data. | 7. Low-power supply. |
| 3. Data confidentiality. | 8. Self-sufficiency. |
| 4. Data reliability. | 9. Technology persistence over time. |
| 5. Fast response time. | 10. Universal access. |
Can I use your measurement devices while maintaining my current software infrastructure?
Yes, you own your data. To integrate your data, you can either use our CLI (command line interface) for which we have plenty of code examples or for more advanced users, by choosing the VCP (Virtual COM Port) option when selecting your product.
How many devices can be simultaneously managed by your software tools?
Unlimited number of similar and different devices, provided your system supports the load.
What is your warranty policy?
Dracal Technologies guarantees the incomparable speed of use and the exceptional quality of its products, that they are made of new materials, assembled and tested in our factory in Canada, in processes that respect human rights and the environment. We guarantee the absolute absence of any form of programmed obsolescence, and that conversely, we deploy sustained efforts on both our electrical and mechanical designs to extend the life of our devices as long as possible so that the results of the efforts invested by our customers last over time but also, and just as importantly, to preserve our planet.
