Term Definition
Switch An electrical device for connecting and disconnecting power to a circuit,
having two states, on (closed) or off (open). Ideally having zero impedance
when closed and infinite impedance when open.
Synchronous (1) Hardware - A property of an event that is synchronized to a reference
clock. (2) Software - A property of a function that begins an operation and
returns only when the operation is complete.
Syntax Comparable to the grammar of a human language, syntax is the set of
rules used for forming statements in a particular programming language.
System Noise A measure of the amount of noise seen by an analog circuit or an ADC
when the analog inputs are grounded.
TankMaster Totalflow Control System for LevelMaster Tank Units.
Tap To cut threads in a round hole so that other fittings or equipment can be
screwed into the hole. Also to make an opening in a vessel or pipe.
TBUS Communication abbreviation for Transmit Bus.
TCP/IP TCP/IP – This is the basic communication format for the Internet, and for
much of what happens on a corporate network. Virtually all networked PCs
and other computers have an “IP address” having the format
xxx.xxx.xxx.xxx (xxx can range from 0 to 255 in most cases). You can see
the ip address of your PC by going to the start menu, selecting run, and
entering cmd. A “DOS Box” will be displayed on your screen. Type
ipconfig to get the ip address. When you enter a URL (e.g.,
www.TotalFlow.com) in a browser, a DNS server (on the network)
resolves this into an IP address and directs your request to the machine
with that address.
TDS32 Totalflow DDE Server that allows Microsoft Windows applications with
DDE capabilities to communicate with Totalflow’s equipment. For example
data can be retrieved and placed in an Excel spreadsheet.
Temperature Coefficient An experimental number used to modify the calibration of a device
(Totalflow transducer) to account for changes in environmental
temperature.
Temperature, Ambient The temperature of the air, atmosphere or other fluid that completely
surrounds the apparatus, equipment or the work piece under
consideration. For devices which do not generate heat, this temperature is
the same as the temperature of the medium at the point of device location
when the device is not present. For devices which do generate heat, this
temperature is the temperature of the medium surrounding the device
when the device is present and generating heat. Allowable ambient-
temperature limits are based on the assumption that the device in question
is not exposed to significant radiant-energy sources such as sunlight or
heated surfaces.
Temperature, Flowing Temperature of the flowing fluid. Usually gas and measured by an RTD.
Terminal Mode Man-Machine interface tool used as and engineering interface with
equipment.
Termination Placement of a connector on a cable.
Termination Panel A circuit board with screw terminals or other connector system that allows
convenient connection of field signals to a data acquisition or
communication system.
