Thermocouple Calibrators vs. Thermocouple Calibration
Hey guys, this is Chet from Omega. We get a lot of questions about Thermocouple Calibrators vs. Thermocouple Calibration.
They sound similar but they are vastly different… stick around, and we’ll break it down for you right here.
So Thermocouple Calibrator vs. Thermocouple Calibration… what’s the diff?
First lets talk about Thermocouple Calibrators:
This is a thermocouple calibrator. It’s used for calibrating devices that use thermocouples as an input signal such as:
- Meters
- Transmitters
- Data Loggers
- Recorders
Now let’s talk Thermocouple Calibration:
We know that most of our applications require a high level of accuracy… but if you’re working within the confines of industry standards such as ISO or ANSI among others, any calibration of your equipment must be performed by a certified calibration lab, like Omega’s New Jersey Calibration Center, that provides you with an NIST traceable calibration certificate to the Calibration level that is required by your certifying body.
So what takes place in a typical Thermocouple Calibration?
We set-up this mock calibration to demonstrate the process. And just to drive the point home once more…. Kids, don’t try this at home. like I said, a certified calibration needs to be done by a certified calibration lab.
So here, we’re calibrating a type K thermocouple probe.
We have it inserted into our dry block, and we have it set at 100°C. We’re using this as our reference. We then have our type K thermocouple connected to our reference probe that’s inserted into an Ice bath, maintaining a temperature of 0°C. Then we have the other side of the reference probe connected to a digital multimeter giving us the raw millivolt signal from the thermocouple. As you can see on the multimeter, the millivolt signal matches the temperature of the dry-block. So this thermocouple passes our mock calibration!
