Computer Numerical Control allows the control of motion in an accurate
and programmable manner through use of a dedicated computer within a
numerical control unit, with a capability of local data input such that
machine tools are freed from the need for "hard-wired" controllers.
a physical network medium that offers large bandwidth and the ability to support high data rates with immunity to electrical interference and a low incidence of errors.
Common Business Oriented Language is a programming language commonly used for data processing.
The ANSI established colour code for thermocouple wires in the negative
lead is always red. Colour Code for base metal thermocouples is yellow
for Type K, black for Type J, purple for Type E and blue for Type T.
Component object model
Predictable normal random variation present in every process due to the combination of existing inputs.
The output form or type of control action used by a temperature
controller to control temperature, i.e. on/off, time proportioning, PID.
|Common Mode Rejection Ratio||
The ability of an instrument to reject interference from a common voltage at its input terminals with relation to ground. Usually expressed in db (decibels).
the mechanism for information transmission.
Sequential excitation of motor windings to maintain the relative phase angle between the rotor and stator magnetic fields, within specified limits, to control motor output. In brush dc motors, this function is accomplished by a mechanical commutator and carbon brushes; in brushless motors, it's done electronically using rotor position feedback.
the ability for two devices to communicate together of software to run on a particular hardware platform.
Alloys used to connect thermocouples to Instrumentation. These alloys
are selected to have similar thermal electric properties as the
thermocouple alloys (however, only over a very limited temperature
An addition of specific materials or devices to counteract a known error.
A program that translates a high-level language program into a computer's machine code or some other low-level language.
The restructuring of the engineering process so that the input of all
concerned parties, including manufacturing, sales and even customers,
are heard from during a project's conception.
