Installation measurement and monitoring

Measure and monitor. Installation at the test sites will be closely monitored against an established timetable, as well as in terms of our established PSM criteria and goals. Throughout this process, we will solicit feedback and other commentary from the pilot sites for incorporation into ongoing process improvement.

Measuring and monitoring PSM installation helps assure consistency and quality control in addition, effective monitoring helps keep local expenditures and schedules on track. In effect, these activities protect the investment you, your team, and your company have made in the course of your work so fac and for this reason they warrant continuing attention. 

Sensors also enable equipment operating conditions to be measured and monitored. Some types of thermocouples to measure temperature are inherently fragile and may be mounted on a temporary PA film carrier, which is tough, flexible and dimensionally stable with a continuous rating of 230 "C, peeled off prior to installation. Other models are constructed on an insulated PA carrier. Housings may be made from glass-filled PA, PBT, PC, thermoplastic polyester or ABS. 

The number of Sis, present in today s chemical process industry is overwhelming as discussed by Tixier (Tixier et al., 2002). These indicators are categorized in several ways in literature, for example pro-active versus reactive indicators. Many of these categories are not unambiguous. Some authors, like Kletz (Kletz, 1998) define proactive as prior to the operational phase of an installation while other authors, like Rasmussen et al. (Rasmussen et al., 2000), define pro-active as prior to an accident. In this thesis two categories of indicators are used, i.e. pro-active and reactive indicators. Here the definition of Rasmussen (Rasmussen et al., 2000) is adopted, who defined pro-active indicators as indicators before an accident and reactive indicators as indicators after an accident. Moreover, the pro-active indicators are divided into predictive and monitoring indicators. The monitoring indicators use actual events as a measure for the likelihood, while the predictive indicators predict the likelihood. 

The electrical circuit, Figure 17.2 (b), consists of two 1.5 V dry cells that provides a voltage applied to the above titration cell. It is duly controlled and monitored by the potential divider (R) and is conveniently measured with the help of a digital voltmeter (V). Finally, the current flowing through the circuit may be read out on the micro-ammeter (M) installed. 

F. Monitoring Impurities. Because of cost and complexity, the automatic monitoring of the glove box atmosphere is not common in academic laboratories, but some industrial and many atomic energy installations employ continuous monitoring. Water is easier to measure than oxygen and fairly simple mois-... 

Instrumentation will include field instruments used in the manufacturing process and other instruments assoeiated with special tasks, such as that of monitoring laboratory or computer room environmental eonditions. The accessibility of instruments must be such as to permit their eleaning and maintenanee. Siting is also important, and instruments should be installed as close to the point of measurement as possible. The placement of flowmeters in piping dead-legs should be avoided. Careful consideration should also be given to the appropriate position of other instruments sueh as thermometers and thermocouples so that they, too, can fulfill their measurement and eontrol functions. Construction materials that come into direct contact with the pharmaceutical or healthcare production process stream must not contaminate or affect the manufactured product in any way. Instrument lubricants and coolants must not come into contact with in-process product or equipment. The reliability of instruments should also be considered for instance, a pressure transmitter that uses atmospheric pressure as its reference may suffer from poor reliability. A draft calibration schedule may also be prepared. 

The measurements on the research facility were carried out at stationary or quasi stationary conditions. The measurements of air flows, gas temperatures, gas composition, and heat output were analysed continously and monitored online. The gas composition was analyzed in the flue gas after the boiler exit with industrial gas analyzers. For the analysis of the hot gas in the reduction zone a suction pyrometer combined with a probe for detection was used. With this probe also short fluctuations could be monitored with extremely short delay. Besides, a hot gas sampling line with different analyzers for measuring the gas in the reburn zone was installed. Table 2 gives on overview over the gas analysis equipment. 

A computer controlled system is designed and installed to automatically measure and control the deposition parameters such as pressure, flow rate, depositing temperature and time. In some cases, a gas analyser is used to monitor the CVD process [15, 16], This subsystem is usually incorporated within the relevant aforementioned subsystems to ensure the quality of the deposition. 

Consequently, our first attempt is to install measuring devices that will monitor T and V directly. For the present system this is simple by using a thermocouple (for T) and a differential pressure cell (for V). 

Pure ethylene oxide for use in conjunction with a diluent gas and 20 80 mixtures of ethylene oxide are potentially explosive all electrical equipment, switchgear, and monitoring and measuring systems used in association with these forms of the sterilant must be sparkproof. Serious consideration should be given to the location and design of gas stores and sterilization suites in relation to other areas within a factory, in relation to other factory buildings, and in relation to the local community. Blow-out roofs, windows, and walls are commonly installed with the intention of channelling the shock waves from an explosion in the direction of least harm. 

In addition to the clay barrier and the heaters, 632 sensors of diverse types were installed. The sensors monitor the different thermo-hydro-mechanical processes that occur in both the clay barrier and the surrounding rock throughout the entire life of the test. A heating stage of more than three years was planned, followed by dismantling of the test. The present paper reports on the measurements recorded during the first 1000 days of operation.
