9 Different Types of Calibration You Should Know

Image default

When you get a new tool, it’s important to calibrate it. Calibration is the process of making sure that a device or machine is accurate. When you calibrate something, you’re testing its precision and accuracy. You can learn additional about this topic in our post on how to calibrate your tools! In this post we’ll discuss some common types of calibration: temperature, pressure, flow rate, torque force and electrical currents along with frequency & time (that might not sound like fun).

Temperature Calibration

Temperature Calibration

Temperature calibration is the process of measuring the temperature of a device and comparing it to a known value. It is used to ensure that the device is operating within its specified range. For instance, if you have a thermometer that reads in Celsius degrees, you will need to calibrate this device at room temperature and then again when it gets cold outside. This way you can say with certainty how many degrees it is outside without having to rely on your own estimation or guesswork!

Pressure Calibration

The pressure calibration or pressure gauge calibration is used to check the accuracy of pressure sensors. It is the most important calibration in a system. The pressure sensor and pressure switch will be checked against an external reference pressure source and compared with the internal setting of that sensor. This can be done either manually or automatically by using an electronic device called a calibrator, which sends air into a sample chamber and then measures the resulting output signal from its electronics or software.

The following are some key considerations when doing this type of calibration:

  • The level of accuracy required for your application (e.g., within 0-5% range)
  • Whether you want to perform only one or multiple steps (i.e., dry/wet versus wet/wet)

Flow Calibration

Flow Calibration is used to measure the flow rate of a fluid through a pipe or duct. It can be used to ensure that equipment is operating correctly, and it also ensures that the flow rate of a fluid complete a pipe or duct is within acceptable limits. For example, if you have an oil pipeline running under your home and want to find out how much oil has been lost into your yard, you would need a flow meter for this purpose.

Torque Calibration

Torque calibration is the process of determining how much resistance to put on a tool when turning it.

It’s important because you can use torque calibration to make sure that your tools are calibrated properly and working at their best. If they aren’t calibrated properly, they may not work as well as they should or could cause damage to other parts of your machine. You may have already been performing torque calibration without even knowing it! When you tighten a bolt, screw, or nut by hand with a wrench, that force is an example of torque calibration—you apply more or less force based on what kind of bolt/screw/nut it is and whether or not you have enough space in which to work with them (e.g., if there’s only one hand available). If a bolt feels loose after being tightened by hand then chances are there wasn’t enough applied force during calibration so we recommend using an electronic-type device like this one instead.”

Electrical Calibration

Electrical calibration is the process of measuring the accuracy of an electrical measurement device. It can be performed by measuring the output of a device with an electrical standard and comparing it to the known value.

Electrical calibration is usually required for instruments that measure voltage, current, or resistance.

Force Calibration

Force Calibration is the process of calibrating force sensors. It’s used to measure the amount of force being applied by the sensor and ensure that it meets a certain level of accuracy.

Force calibration is used for testing products that require high levels of precision, such as surgical instruments or aircraft components.

Acceleration Calibration

Acceleration is the rate at which an object accelerates. The faster an object moves, the more gravitational force it experiences. This means that there is less time for it to keep up with its own momentum—it’s like being stuck in a sand trap when you’re trying to run in place on a treadmill (which I find hilarious). Accelerate too quickly and you’ll get bogged down by gravity; accelerate too slowly and your body may not be able to save up with what’s happening around it or even worse, stop altogether!

Acceleration calibration determines how fast a device can move without getting stuck by gravity. It also helps determine how much time is needed between steps so that they don’t feel like they are running into each other due to their proximity on screen.

Humidity Calibration

Humidity Calibration is a procedure wherein you can calibrate your humidity instrument.

Humidity calibration requires two things: the first one is that your device must be at constant temperature and humidity conditions before you start your calibration process; the second requirement is that your device must be in good working condition with no leaks or other problems that may affect its accuracy.

This process will verify how well your instrument performs under various environmental conditions so it’s important that you follow all protocols correctly if you want accurate measurements from your instrument later on when used in actual operations.

Frequency & Time Calibration

Frequency & Time Calibration is used to check the accuracy of a frequency signal. A device that generates a signal is connected to the oscilloscope, and then the oscilloscope checks if it is emitting an accurate signal. If there is any deviation, then it can be corrected by adjusting the setting on this particular device. In most cases, Time & Frequency Calibration requires an external source for calibration. For example, you can use a frequency generator for this purpose or simply a clock that has been synchronized with other clocks in your city/state/country/universe (whatever works best for you).

Frequency & Time Calibration can be done with a frequency generator. This is because there are times when we need to know how fast our tools are running before we do anything else with them; therefore, they must be calibrated first so they don’t malfunction later on during their job process or performance time frame.

Ultrasonic Calibration

NDT ultrasonic testing is a non-destructive testing method that uses sound waves to inspect the internal structure of materials. This method can be used to detect cracks or flaws in many different types of materials, including metals, ceramics and polymers. It is one of the most common forms of NDT because it is fast and inexpensive compared to other methods.


When you’re looking to calibrate your instrument, it can seem like a daunting task. There are so many different types of calibration and they all have their own unique qualities. The key thing is that you choose the right type for your needs.
