One of the tendencies in measurement technology development is the development
of measurement systems. By the measurement systems, we refer to a set
of material and organizational resources, as well as programs for information
processing, aggregated in order to obtain, transmit, and process measuring data,
and to display and store them. The measurement system is equipped with a PC
computer or a microprocessor chip; its task is to control information flow in the
system, to process measuring data, and sometimes to store them. The computer or
the microprocessor chip is a system controller, that is to say, a device managing
the system. The measurement systems described in this book are exclusively
digital systems. Measurement systems with the personal computer (PC), named
computer-based measurement systems, are of great importance. Considering the
widespread use of PCs in both industrial and research measuring laboratories, the
building of a computer measurement system usually does not imply the purchase
of a separate computer, but allows the utilization of the existing ones. This is
especially important and economically effective in the case of building up computer
measurement systems for the realization of temporary measuring tasks.
Separate classes of computer measurement systems are the simplest two-component
systems, composed of one measuring instrument plus one computer as the
system controller. It is self-evident that the possibility of applying an existing
computer for setting up the simplest measurement system decreases construction
expenses of such a system considerably.
Measurement systems and the role of the sensors within these systems is of critical importance to engineers involved with the monitoring, control, and development of equipment and processes in a wide range of high-tech industries. This hands-on book serves as a one-stop resource in this evolving and increasingly complex area. Coverage of new wireless measurement systems and wireless GSM interfacing makes this title unique, providing in-depth, practical knowledge professionals won't find in any other book. Moreover, the book introduces new, cost-effective measurement technology utilizing www servers and LAN computer networks. From computer-based measuring systems, electrical thermometers and pressure sensors, to conditioners, cassette measuring systems, and virtual tools, this authoritative volume is an essential professional reference and an excellent information source for academics studying in related areas. |
