What is Torque Boosting in Variable Frequency Drive (VFD)?
High inertial motor loads can be started by programming the V/f pattern in VFD. This feature is known as Torque Boosting.
What is SAMA Diagram?
SAMA is an acronym of Scientific Apparatus Makers Association. SAMA diagram sometimes referred to as control functional diagrams.
What is a Head Mount Temperature Transmitter? – Advantages
Head mount temperature transmitter converts the signal from RTD or thermocouple into 2 wire loop powered 4 to 20 mA signal.
Polarization Index (PI) Test and DA Test
Polarization Index (PI) and DA Tests are used to check the insulation resistance value of insulating materials used for electrical system.
Why 4 wire RTD Measurement Accuracy is better than 2 and 3 wire RTD?
The 4 wire RTD accuracy is better than the 2 or 3 wire RTD’s as temperature measurement based on voltage signal instead of resistance.
Purpose of Gateways, Bridges & Routers in Networking
Let’s Learn the purpose, advantages, disadvantages of gateways, bridges, and routers in communication networks.
Why 4-20 mA Current Signal is used instead of Voltage Signal?
Learn why 4-20 mA current signal is used in industrial automation plants instead of a voltage signal 0-5v, 0-10v etc.
