A device that converts linear or rotary displacement into digital or pulse
signals. The most popular type of encoder is the optical encoder, which
uses a rotating disk with alternating opaque areas, a light source, and a
photodetector.
All conditions in which a transducer may be exposed during shipping,
storage, handling, and operation.
A liquefiable hydrocarbon product consisting primarily of ethane and
propane.
See Erasable Programmable Read-Only Memory. The PROM can be
erased by ultraviolet light or electricity.
ROM that can be erased using Ultraviolet Light. The EPROM maybe re-
programmed by removing the EPROM from the circuit and using
special equipment to write to it.
A colorless hydrocarbon gas of slight odor having a gross heating value
of 1,773 Btu per cubic foot and a specific gravity of 1.0488. It is a
normal constituent of natural gas.
A colorless unsaturated hydrocarbon gas of slight odor having a gross
heating value of 1,604 Btu per cubic foot and a specific gravity of
0.9740. It is usually present in manufactured gas, constituting one of its
elements and is very flammable.
European Union. Formerly known as the European Community (EC).
Members of this union are replacing individual national regulations of
member countries with a series of Directives. These Directives are
legislative instruments which oblige member states to introduce them
into their existing laws. These directives harmonize a variety of existing
practices, preserve the different legal traditions and settle constraints
for further developments.
Important incident: an occurrence, especially one that is particularly
significant.
Stored records specifying a notable change. The XFC stores up to 200
records, containing: Time, Day, Description, Old Value, New Value.
Signals or interrupts generated by a device to notify another device of
an asynchronous event. The contents of events are device-dependent.
Potential Explosive.
Explosion Proof Integral Multivariable Transducer.
A plug-in circuit board that adds features or capabilities beyond those
basic to a computer, such as a data acquisition system expansion
board.
Correction factor for the change in density between two pressure
measurement areas in a constricted flow.
The spaces provided in a computer for expansion boards than enhance
the basic operation of the computer.
