GLOSSARY

9.0 GLOSSARY

Listed here are terms used in the field of temperature measurement; terms and abbreviations that appear on a Moore XTC Communicator (MXC) screen; and terms relevant to HART networks.

ALPHA - The average percent change in resistance per degree of a pure metal resistance device between 0 and 100 degrees Centigrade. Designated by the Greek letter alpha.

ANALOG SIGNALING - A low current signal of 4 to 20 mAdc from a Field Instrument to a Primary Master or non-signaling hardware.

ANSI - American National Standards Institute

ARCH = ARCHIVE - MXC screen abbreviation

ARCHIVE - A database of user-set parameter values that is stored in an MXC. An archive is usually a complete configuration. Each archive is assigned a unique number (1-99).

AWG - American Wire Gauge

BARRIER - A device whose function is to limit the voltage and current in the hazardous area even if certain types of faults occur on the non-hazardous side of the Barrier.

BARRIER RESISTANCE - The maximum end-to-end resistance of a barrier, as specified by the barrier manufacturer. If both supply and return barriers are used in a network, the barrier resistance is the sum of the end-to-end resistance of both barriers. For active barriers that use resistance to limit current, the barrier resistance is the internal resistance between the hazardous area terminal and the barrier internal node where voltage is regulated.

COMMISSIONING - Testing of a transmitter and loop to verify transmitter configuration and loop operation and wiring.

CONF/CONFIG = CONFIGURE - MXC screen abbreviation

CONFIGURATION - A database (or archive) created using an MXC and downloaded to a transmitter to define transmitter operation.

CONFIGURE/CONFIGURING - The entering of specific parameter data into an MXC to be downloaded to a transmitter to define that transmitter's operating characteristics.

CONNECTION HEAD - An enclosure attached to the head of a thermocouple within which the electrical connections are made.

CONT = CONTINUE - MXC screen abbreviation

CURRENT SENSE RESISTANCE - The resistance in a Network across which the field instrument (Transmitter) signal voltages are developed.
