Gauge Vs Instrument

You may wonder about the differences between the gauge and instrument. Both of them we use in many times and many places. In this post, we will briefly break down their differences. 1. Gauge A gauge comes in a fixed dimension which has only single readout. For example, a single feeler gauge comes in a … Read more

What is Power Supply?

unregulated power supply circuit

A power supply is a critical part of a particular measurement instrument. Almost all parts of a particular measurement instrument require electricity to run. The power supply in this case provides electricity to energize the system right from the transducer (sensor); we mean the passive one, goes to the microcontroller, and all the way down … Read more

What is Display?

Almost every single human in the world carries a display that is embedded into such a device called a cellphone or smartphone at this very moment. However, we might have no idea what type of display that is and how the mechanism works behind it. In this article, we are trying to bring the best … Read more

What is Microcontroller?

The question might arise from you when trying to determine what is actually controlling the daily appliances you often meet, such as a printer, microwave, or even a simple line-following robot. Well, the answer you have been seeking is right here in this article. The thing that controls those devices called a microcontroller. By reading this … Read more

What is DAC (Digital to Analog Converter)?

We do agree that almost every aspect of our life is processed by the digital processing system. It’s the reality that most of us already at least have a laptop, PC, or smartphone. However, the world we are living in at the moment is the analog world. It is logical that the data conversion from … Read more

What is Transducer?

A transducer is an electronic device that functions to convert the energy from a certain form into another form. The process to convert the energy from one form into another is called transduction. The conversion is going through two processes, which are sensing and transducing the physical quantity (units) such as length, pressure, temperature, sound, … Read more

Repeatability in Measurement

Repeatability is a term in metrology that is an important aspect to consider when you are going to use a certain measuring tool if you demand a high degree of precision. It also indicates the quality of measurement provided by your tool. What is Repeatability? Simply, repeatability is a condition of how consistent the measuring … Read more

What is ADC (Analog to Digital Converter)?

An ADC (analog to digital converter) is an electronic circuit that converts the analog data (continuous) from nature into digital data (binary). The ADC circuits can be found as a stand-alone ADC IC module or embedded into microcontrollers. The following features are best for you to understand before you go deeper about ADC. ADC Features … Read more

Uncertainty in Measurement

The first thing that you have to know is that there is not exactly accurate measurement. Error is anywhere. As a human, we cannot realize the hidden error that is caused by the environment and also the internal system of the measuring instrument. Because we cannot spot the error, it’s reasonable we doubt the reading. … Read more

What is Measurement Traceability?

Traceability in measurement or measurement traceability is the condition where no links are missing to the real agreed reference standard. The real agreed reference standard means a particular reference that the nations over the world agree to establish it as standard. For example, the nations over the world establish the path traveled by light in … Read more
