This is a video about thermocouple calibration. This video shows step by step how to calibrate the thermocouple using the transmitter’s compensation circuit. The thermocouple is calibrated by the fluke model 744 calibrator. First look at the fluke, it shows the temperature is 200 F, using the datasheet of the thermocouple, 200F is equal to 4.907mV. Then connect wire to […]

Below is video tutorial about pressure measurement. DP (Differential Pressure) is widely used principle of all type of fluid flow. The overall energy will remain constant, because while the kinetic energy increasing, the pressure energy is decreasing and while the pressure energy increasing, kinetic energy decreasing. The crude oil extraction on the sea bay is using this principle. To increase […]

Below is video tutorial about electromagnetic flow meters. On this tutorial demonstrate the features of electromagnetic flow meters. Electromagnetic flow meters is widely used in conductive liquids such as water, acid and alkalies. Electromagnetic flow meters is using the principle of Michael Faraday 1832 discovery. When any liquid move into the magnetic field, a voltage is produced. How big the […]

Below is video tutorial about PC based control. PC based control is widely used in proses automation, machine controllers, industrial controllers and PLC. PC is developed in early 1990 when the chip processor is very expensive. The chip need special handling like special power supply and cooling. Intel and AMD have realized they can used a standard PC for controlling. […]

Below is video tutorial about basic of level measurement. As we know, we have been measuring level since the days of the Pharaoh, but why is it still so hard? That’s because most process engineer do not think level is control function but process function. Control Editor in Choef Walt Boyes will explain about the basic of measuring level and […]

A R-2R ladder circuit as the binary current divider that is finest application in digital to analog conversion. This video shows how to analyze the R-2R ladder circuit. In this video, the circuit has three nodes. First, this video shows analysis of the resistance on third node. Since the 2R is connected in parallel with 2R, they will give the […]

This is a video about high speed analog to digital converter. Analog to digital converter (ADC) is a device that is used to convert an analog signal into digital. For example femtocharge, it implements the gain trough capacitor scaling, each pipeline stage has its input. Reducing the capacitance will increase the voltage. Here is the video : The femtocharge has […]
