A Multivariable Transducer that is an integral part of the flow computer,
measuring DP and SP. This refers only to the transducer portion of the
device and makes no assumption whether or not the circuitry is located
as part of the unit, or if the circuitry is located on the Mother Board and
attached via wiring. Also see Multivariable Transducer.
A circuit component consisting of a piece of semiconductor material
containing up to thousands of transistor and diodes. A chip.
An ADC whose output code represents the average value of the input
voltage over a given time interval.
Usually refers to the hardware that provides communication between
various items of equipment.
The area between two liquids that are not easily mixed, i.e. oil and
water.
A disturbance to the signal in any communications system.
An instrument which will not produce any spark or thermal effects under
normal and specified fault conditions, that is capable of causing ignition
of a specified gas mixture.
A circuit in both analogue and digital systems that provides an output
that is inverse to the input.
Converts DC to AC at a high frequency.
Interrupt signal from the I/O modules.
i/o Battery Voltage- Unregulated 13.8 volts. Host supplies 2.5 amps to
the I/O modules.
Unregulated 5.6 volts from the host for I/O modules.

A hydrocarbon of the same chemical formula as butane but different
molecular structure, resulting in different physical properties, notably
lower boiling point. Gross heating value 3261 Btu/cu. ft. gas.
Laboratory technique where gas sample is tested after removing
liquids, therefore not allowing the atomized liquid to return to the
gaseous state, changing the sample accuracy.
The reduction of the capacity of a system to respond to an external
force by use of resilient isolating materials.
A hydrocarbon of the paraffin series having a chemical formula of
C5H12 and having its carbon atoms branched.
