Basics of 4-20mA Current Loop
The 4-20 mA current loop is a very robust sensor signaling standard. Â Current loops are ideal for data transmission because of their inherent insensitivity to electrical noise. In a 4-20…
Rotary Level Switch Working principle Animation
Animation Credits : KANSAI Automation Working Principle: During normal operation (no material present) a synchronous motor rotates the paddle at 1 RPM. When this paddle rotation is impeded by material,…
Basics of Differential Pressure Level Transmitters
The importance of level measurement cannot be overstated. Incorrect or inappropriate measurements can cause levels in vessels to be excessively higher or lower than their measured values. Low levels can…
Rotameter Working Principle and Animation
A rotameter is a device that measures the flow rate of liquid or gas in a closed tube. It is one type of variable area flow meter.
Working Principle of Flow Switch with Animation
Flow Switch operating principle is based on a free-floating magnetic piston that responds only to the motion of fluids within the pipeline.
Working Principle of Pressure Gauge
The Bourdon pressure gauge uses the principle that a flattened tube tends to straighten or regain its circular form in cross-section when pressurized. Although this change in cross-section may be…
