Instrumentation diagnostics

Advantages of this analytical instrument include (1) analysis can be confined to very small (microsamplcs) amounts of materials (2) the particular material to be analyzed need not be physically separated from its surrounding materials, as is often required with many analytical methods and (3) through the development of associated instrumentation, diagnostic techniques, and information displays, the method can be quite fast. Limits of detection in solid solution are from approximately 0,005 to 0.5%, depending upon the elements and sample matrixes involved. See Fig. 5. Concentrations as low as 10-16 gram may be measured. 

Specialty membrane devices used as sensing elements and electrode components are often built permanently into instruments. Diagnostic or medical devices are often single-use disposable items.

Another feature of a well-constructed instrument diagnostic package is information about the unit, such as camera type, grating information, what optics are used, and so forth, stored in ROM (read-only memory) as part of the instrument s electronics. This allows the control system to query the analyzer and automatically configure to it, as well as providing service technicians with valuable information, which can translate into a quicker repair.

Now days the problem of establishing of regional diagnostic centers, their well instrumentation with all types of diagnostics technologies and devices is very actual. Only such approach will help to solve the regions safety issues.

Figure 18.24(b) illustrates the use of a leakage current monitor. The instrument can be used to display or monitor on a computer remotely and store data at intervals as required to provide diagnostic information. Now it is easier to take corrective measures in time. The instrument can also be programmed to give an alarm at a preset value of I, when the actual operating conditions exceed this. 

The diagnostics applied to shock experiments can be characterized as either prompt or delayed. Prompt instrumentation measures shock velocity, particle velocity, stress history, or temperature during the initial few shock transits of the specimen, and leads to the basic equation of state information on the specimen material. Delayed instrumentation includes optical photography and flash X-rays of shock-compression events, as well as post-mortem examinations of shock-produced craters and soft-recovered debris material. 

To achieve effective monitoring and diagnostics of turbomachinery, it is necessary to gather and analyze both the mechanical and aerothermal operating data from the machines. The instrumentation and diagnostics must also be custom tailored to suit the individual machines in the system, and also to meet the requirements of the end users. The reasons for this are that there can be significant differences in machines of the same type or manufacturer because of differences in installation and operation. 

The monitoring of turbomachinery mechanical characteristics, such as vibrations, has been applied extensively over the past decade. The advent of the accelerometer and the real-time vibration spectrum analyzer has required a computer to match and utilize the extensive analysis and diagnostic capability of these instruments. 

Much present electronic equipment deals with signals which are not sinusoidal and which may not even be periodic in nature. However, these signals can be divided into a series of components, each of a single specific frequency, and each can then be studied in turn in order to determine its characteristics. Where plant instrumentation is concerned, this technique can be particularly useful for diagnostic purposes.
