Basic concept of HART

Looking at a standard loop-powered (2-wire) process transmitter circuit, we see the transmitter, a DC power supply (voltage source), and usually a 250 ohm resistor to create a 1 to 5 volt signal readable by any voltage-sensing indicator, controller, or recorder: The transmitter’s primary function in this...

Transmitter:- 3 valve manifold operation

Manifold Operation :- Improper installation or operation of manifolds may result in process leaks, which may cause death or serious injury.  Always perform a zero trim on the transmitter/manifold assembly after installation to eliminate any shift due to mounting effects. Three valve configurations shown: In normal operation the...

Speed Control OF DC Motors

DC electric motors generate torque by a reaction between two magnetic fields: one field established by stationary “field” windings (coils), and the other by windings in the rotating armature. Some DC motors lack field windings, substituting large permanent magnets in their place so that the stationary magnetic field...
