What is Magnetic Tape Recorder ?
A recorder is used to produce a permanent record of the signal that is measured. A record is used to
Seismic Displacement Sensing Accelerometer
When a spring – mass – damper system is subjected to acceleration, the mass is displaced, and this displacement of
Electrical Torsion Meter Principle
Torque Measurement using slotted Discs Due to the applied torque, there is a relative displacement between the two slotted discs.
Types of Control Valves Noise
Noise is the result of energy dissipation in the control valve. Types of Control Valves Noise The major sources of
Control Valves Chemical attack Problems
Corrosive chemicals may attack the metal components of control valves if those components are not carefully selected for the proper
FF Function block Modes
All FF function blocks must support multiple modes of operation, describing how the block should execute its intended function. Several
FF Signal Status
FF function block programming bears a strong resemblance to analog function block circuit design, where specific tasks are divided up
Foundation Fieldbus Standard Function Blocks
The FF standard specifies many different function blocks for the construction of control algorithms. Ten of them are considered “basic”
H1 FF Data Link layer
Like so many other industrial data networks, FOUNDATION Fieldbus is an “unswitched” or “broadcast” type of network. This means all
H1 FF Physical layer
Layer 1 of the OSI Reference Model is where we define the “physical” elements of a digital data network. The
