The daq dictionary continues with B-C part with a goal to get you closer to data acquisition.
Backbone
The main multi-channel link in a network that branches into smaller links.
Background noise
Inessential signals someone may confuse with measured signals.
Batch process
Any procedure on which processes is carried out on a limited number of articles.
Bathymetry
Measuring of the depths of geographies at the bottommost of the sea, especially by echo-sounding.
Bipolar
A signal that varies between a negative and a positive value.
Bluetooth
Short-range wireless communication.
B-Type Thermocouple
Platinum-rhodium thermocouple with a temperature variation of 600 to >1700 C.
Bus
Sends data from the data acquisition system to a computer. Network systems like ethernet are not generally regarded as buses.
Cable Gland
Locks electric cable entering equipment and provides a closure between the external and internal exteriors of the gear.
Calibration
Calibration compares a data acquisition device’s performance to an accuracy standard and adjusts the performance as necessary.
Celsius
A scale for temperature measurement in which the freezing point of water is 0 and the boiling point 100 degrees. The symbol is C.
Cold Junction
The reference junction of a thermocouple which is kept at a constant temperature.
COM port
A connection on a computer into which a serial device may be plugged.
Common-Mode Signal
A signal smeared simultaneously to both inputs of a differential amplifier.
Contact Rating
Refers to the power that can be safely switched with a relay. Quoted for non-reactive load, that is without capacitance or inductance.
CMOS
Complimentary metal-oxide semiconductor.
Crosstalk
When one channel’s signal causes an undesired effect on another.
Current
Current is used to transmit signals in noisy environments.
