In addition to commercial systems, there are quite a number of oscillator circuits that can be built from relatively inexpensive components to perform tiie essential measurements without the functions and convenience of a packaged instrument [22-28]. Both the commercial systems and most of these home-built oscillator circuits yield just one piece of information the resonant frequency of the TSM device. While this is sufficient for mass-loading-only applications like vacuum deposition of metal films, for some electrochemical processes, and even for appropriately selected chemically sensitive films, it can fall short when changes in the mechanical properties of a surface layer or contacting medium are significant [29].

Packaged Instrumentation. Most evaporation systems are supplied by specialist companies, and many are in the form of packaged units that include instrumentation. Section 13.5.4 discusses some of the advantages and disadvantages of this approach. The customer must ensure by means of the unit specification that the instruments supplied will be of acceptable quality. Many purchasers specify types of instruments and acceptable vendors in order to conform to practice in other units on the plant As a minimum, the purchaser should retain approval rights on all the instruments.

FEP, fault tree, gvent tree and piping instrumentation diagram (P ID) editor, accesses ihe package of graphical tools for risk assessment. These tools include the event tree, fault tree and P ID graphical editors. The event tree and fault tree editors are in PSAPACK the P ID editor is in FEP. The event tree editor is used for graphical construction and modification of event trees. The fault tree editor does the same for fault trees the P ID editor does the same for construction and modification of P IDs used in a PSA.

Generally, the driver and bullgear speed is 3600 rpm or less and the pinion speeds are as high as 60,000 rpm (see Figure 44.8). These machines are produced as a package with the entire machine-train mounted on a common foundation that also includes a panel with control and monitoring instrumentation. 

The goal of this book is to help you understand the procedures which are necessary to successfully produce and utilize a calibration in a production environment the amount of time and resources required to do so and the proper use of the quantitative software provided with an instrument or commercial software package. This book is not intended to be a comprehensive textbook. It aims to clearly explain the basics, and to enable you to critically read and understand the current literature so that you may further explore the topics with the aid of the comprehensive bibliography. 

The problem of permeability exists whenever a plastic material is exposed to vapor, moisture, or liquids. Typical cases are electrical batteries, instruments, components installed underground, encapsulated electrical components, food packaging, and various fluid-material containers. In these cases, a plastic material is called upon to form a barrier either to minimize loss of vapor or fluid or to prevent the entrance of vapor or fluid into a product. From the designers viewpoint, the tolerable amount of permeation established by test under conditions of usage with a prototype product of correct shape and material is the only direct answer. 

The migration of package ingredients directly into a food product is often difficult to analyze instrumentally because of interference from food ingredients. Some of these analyses have been made, but it is generally preferable to use food simulating solvents listed in FDA regulations and to carry out extraction tests under the conditions described. 

These objective, quantitative tests have shown that nitrile containers should protect the taste and odor of packaged foods and beverages. But the primary consideration in judging overall package performance, once safety is assured, rests on the subjective evaluations of taste, odor, and appearance. It is well known that the animal senses, in many instances, are far more sensitive than the best instruments and also are capable of integrating the individual effects of the several influences on product quality.
