TERM DEFINITION
Baud Rate Serial communications data transmission rate expressed in bits per second
(b/s).
Bbl See Barrel.
Bcf Abbreviation for one billion standard cubic feet or one thousand MMcf or one
million Mcf.
BG Mix A liquefied hydrocarbon product composed primarily of butanes and natural
gasoline.
Bias Term used when calibrating. Amounts to offset the actual measurement taken.
On a LevelMaster, it refers to adjusting the measurement of the float level to
agree with a calibrated measurement. On an RTD (Resistant Thermal
Detector), it refers to adjusting the measurement of the temperature to agree
with a calibrated temperature. This figure maybe either a positive or negative
figure.
BIAS Current A very low-level DC current generated by the panel meter and superimposed
on the signal. This current may introduce a measurable offset across a very
high source impedance.
Binary Number System based on the number 2. The binary digits are 0 and 1.
Binary-Coded Decimal A code for representing decimal digits in a binary format.
BIOS Basic Input/Output System. A program, usually stored in ROM, which provides
the fundamental services required for the operation of the computer. These
services range from peripheral control to updating the time of day.
Bipolar A signal range that includes both positive and negative values.
Bipolar Transistor The most common form of transistor.
Bit Binary Digit - the smallest unit of binary data. One binary digit, either 0 or 1.
See also byte.
Bits Per Second Unit of data transmission rate.
Blue Dot Technology Technological changes to the DC and ACM Modules, decreasing noise by
changing ground. Allows amplification of the results, gains resolution.
Board Common name used to identify the Main Electronic Board. Also called
Motherboard, Engine Card and Circuit Board.
Boiling Point The temperature at which a substance in the liquid phase transforms to the
gaseous phase; commonly refers to the boiling point of water which is 100°C
(212°F) at sea level.
Bounce Bouncing is the tendency of any two metal contacts in an electronic device to
generate multiple signals as the contacts close or open. When you press a key
on your computer keyboard, you expect a single contact to be recorded by your
computer. In fact, however, there is an initial contact, a slight bounce or
lightening up of the contact, then another contact as the bounce ends, yet
another bounce back, and so forth. A similar effect takes place when a switch
made using a metal contact is opened.
BP Mix A liquefied hydrocarbon product composed primarily of butanes and propane.
BPS See Bits Per Second.
Bridge
Generally a short-circuit on a PC board caused by solder joining two adjacent
tracks.
Bridge Resistance See Input impedance and Output impedance.
British Thermal Unit Energy required to raise one pound of water one degree Fahrenheit. One
pound of water at 32 F
°
requires the transfer of 144 BTUs to freeze into solid
ice.
