Designation which states that the contacts of a switch or relay are
normally open or not connected. When activated the contacts close or
become connected.
Norwegian Certification Bureau
Negative-Positive-Negative (Transistor).
National Pipe Thread.
Nationally Recognized Testing Laboratory.
A condition, such as balance, which results in a minimum absolute
value of output.
American Gas Association Report referring to a specific method to
calculate the Supercompressibility factor.
A standard abbreviation for oxygen.
A hydrocarbon (Alkane) flammable colorless liquid with eight carbon
atoms. Is the 100 point on the Octane Rating Scale.
See Open Circuit Voltage.
See Open Database Connectivity.
Optional Equipment Unit.
The difference in temperature between the set point and the actual
process temperature. Also, referred to as droop.
The unit of resistance usually shown as the symbol "R". One thousand
ohms is written "k" and one million ohms is written "M". Resistance is
measured with a multimeter, set to the "ohms range".
An instrument used to measure electrical resistance.
Object Linking and Embedding. A set of system services that provides
a means for applications to interact and interoperate. Based on the
underlying Component Object Model, OLE is object-enabling system
software. Through OLE Automation, an application can dynamically
identify and use the services of other applications, to build powerful
solutions using packaged software. OLE also makes it possible to
create compound documents consisting of multiple sources of
information from different applications.
This is a data interchange format and supporting software. Typically,
vendors (such as ABB) write OPC server drivers which can talk to their
devices. SCADA system vendors (again like ABB) write OPC clients
that can gather data from OPC Servers. The idea is to provide a
universal way to collect data into a SCADA system regardless of the
equipment vendor. This standard was developed and is maintained by
the OPC Foundation. The Totalflow Driver, TDS32, supports OPC.
A programming interface to databases. Supports the OLEDB interface.
