TERM DEFINITION
Cavitation
The boiling of a liquid caused by a decrease in pressure rather than an
increase in temperature.
CC
Cubic Centimeters. Measurement
unit for measuring volume or
capacity in one hundredth of a meter.
CC
Acronym for Cubic Centimeter.
C-Code
C language (IEC supported programming language)
CCU
See DosCCU, WINCCU, PCCU or WEBCCU.
CCV
See Closed Circuit Voltage.
Cd
Coefficient of Discharge factor.
CE
European Community Certification Bureau.
Cell
The basic electrochemical unit used to generate or store electrical energy.
Celsius (centigrade)
A temperature scale defined by 0°C at the ice point and 100°C at boiling point
of water at sea level.
CENELEC
European Committee for Electro-technical Standardization. Also known as the
European Standards Organization.
Centimeter
Acronym c. Metric measurement equal to .3937 inch.
Central Processing Unit
The central part of a computer system that performs operations on data. In a
personal computer the CPU is typically a single microprocessor integrated
circuit.
Ceramic Insulation
High-temperature compositions of metal oxides used to insulate a pair of
thermocouple wires The most common are Alumina (Al2O3), Beryllia (BeO),
and Magnesia (MgO). Their application depends upon temperature and type of
thermocouple. High-purity alumina is required for platinum alloy thermocouples.
Ceramic insulators are available as single and multihole tubes or as beads.
Certification
The process of submitting equipment to specific tests to determine that the
equipment meets the specifications or safety standards.
Cf
A standard abbreviation for Cubic foot.
CFG
Configuration File. When saving new configuration files, the file is saved as a
*.cfg file.
CFM
The volumetric flow rate of a liquid or gas in cubic feet per minute.
Character
A letter, digit or other symbol that is used as the representation of data. A
connected sequence of characters is called a character string.
Characteristics
Detailed information pertaining to it’s description. The XFC stores this
information in the PROM chip. A feature or quality that makes somebody or
something recognizable.
Charge
The conversion of electrical energy, provided in the form of a current from an
external source, into chemical energy within a cell or battery.
Chip
Another name for integrated circuit or the piece of silicon on which
semiconductors are created.
Chromatograph
An instrument used in chemical analysis, to determine the make-up of various
substances, and often used to determine the Btu content of natural gas.
Chromatography- A method of separating gas compounds by allowing it to
seep through an adsorbent so that each compound is adsorbed in a separate
layer.
CIM
Communication Interface Module. Totalflow’s version is called TFIO
Communication Interface Module.
