Monitoring device

Nickel carbonyl should be used in totally enclosed systems or under good local exhaust. Plants and laboratories where nickel carbonyl is used should make use of air-monitoring devices, alarms should be present in case of accidental leakage, and appropriate personal respiratory protective devices should be readily available for emergency uses. Monitoring of urinary nickel levels is useful to help determine the severity of exposure and identify appropriate treatment measures. Some large-scale users of nickel carbonyl maintain a supply of sodium diethyldithiocarbamate, or Antabuse, a therapeutic agent, on hand for use in case of overexposure. 

Symposium on Toxicology, Carcinogenesis, and Human Health Effects of 1,3-Butadiene (265). Detailed comparisons of various personal monitoring devices are available (266), and control of occupational exposure to 1,3-butadiene has been reviewed (267). ... 

Microbiauy induced corrosion (MIC) probes. Devices are available to measure the amount of microbial activity in some environments. MicrobiaUy induced corrosion is known to be an actor in many corrosion-related problems in processing plants. The monitoring devices for MIC are limited in their range and, at present, are available only for a few specific environments. This is an exciting area for development of corrosion probes and monitoring systems.

Self-audit is a monitoring device used to establish any vaiyiiig degrees of detail or performance of an organization to define areas of deficiency and to correct such deficiencies before they cause further problems. 

They are basically temperature monitoring devices and can indicate the temperature on a temperature scale. They may be one of the following types. 

To detect the above, sensing and monitoring devices can be installed in the motor. Some of these are built-in during the manufacturing stage and others are fitted at site during installation. 

Several types of sensing and monitoring devices are available that are embedded at a motor s vulnerable locations and the hot spots at the manufacturing stage...

The cells of the monitoring devices are very small (ca 5 pi) and the detection is very good. The volumes of the analytical columns are quite small (ca 2mL for a 1 metre column) hence the result of an analysis is achieved very quickly. Larger columns have been used for preparative work and can be used with the same equipment. Most... 

In cooperation with United Technologies Research Center, Elliott has developed a monitoring device dial detects solid particles entrained in gas streams. This device, which Elliott has named Laser Sentry, ... 

All permits must include a cap on emissions which cannot be exceeded without an approved revision of the permit. Permitted sources must periodically test and monitor their emisisons and report on these activihes every 6 months. Civil penalties include fines of not less than 10,000 per day for permit violahons and criminal penalties for deliberate false statements or representations, or for rendering inaccurate any monitoring device or method required in the permit. 

A Btu meter may be used in the fuel-quality system as an aid in determining turbine system efficiency. A water capacitance probe is used for detection of water in the fuel line. A water-detecting device can be incorporated into the corrosion monitoring system. This monitoring device is based on detection of changes in the dielectric constant of unknown fluid components... 

Personal monitoring devices (sometimes referred to as "dosimeters") are carried or worn by individuals and are used to measure that individual s exposure to particular chemical(s). Devices that include a pump are called "active" monitors devices that do not include a pump are called "passive" monitors. Such devices are currently used for research purposes. It is possible that sometime in the future they may also be helpful in lAQ investigations in public and commercial buildings. 

Heaters and furnaces should also be designed in accordance with standards and codes. Boilers and heating units must be inspected periodically in accordance with codes, insurance requirements and state regulations. Proper controls, interlocks and fail-safe instnunentation must be provided. The heaters should also be provided with sight glasses for flame observation, monitoring devices for flame-out detection, and temperature alarms.

Corrosion potential measurement is increasing as a plant monitoring device. It has the very big advantage that the plant itself is monitored rather than any introduced material. Some examples of its uses are ... 

Where possible, some form of continuous monitoring should be employed, although it must be remembered that the results from monitoring devices, probes, coupons etc., refer to the behaviour of that particular component at that particular part of the system. Nevertheless, despite this caution, it must be recognised that the monitoring of the corrosion condition of an inhibited sysem is a well-established procedure and widely used (10 26-10 32). 

Monitoring devices can be installed via standard gate-valves but these are only suitable for low pressures. 

The initial requirement is for the equipment to be fitted with sufficient pressure gauges and other monitoring devices to indicate the conditions under which it is working. It is helpful to mark these with the normal working limits when commissioning the plant. 

Training courses are available in analytical methods of fault-tracing. Computers are also in use which monitor a number of parameters and draw attention to any observed abnormality. The control/ monitoring device may then make a judgement as to the cause, or this may rely on the interpretation of the operator. Considerable use is now made of logic control/monitoring devices which can oversee the operation of a large number of installations from a central computer/observation terminal. 

Additionally, and despite its name, NDT may in fact still require boiler components to be drilled or cut in order to install monitoring devices prior to using the test equipment. 

Carefully follow manufacturer s instructions because blood glucose monitoring devices vary greatly. 

Before starting an IV infusion containing ritodrine or terbutaline, the nurse obtains the patient s vital signs. The nurse auscultates lung sounds to provide a baseline assessment. The nurse places the patient on a monitoring device to determine uterine contractions and the FHR before and during administration.

But reliable, portable monitoring devices are only one element in the equation. The second is the network across which the data they collect can be sent—and here two new technologies are particularly relevant third-generation (3G) mobile telephony and a wireless network protocol known formally as 802.11 and colloquially as Wi-Fi. 

Linking TLC with a tandem instrument differs from combining GC or LC with an appropriate spectrometer. Hyphenation of planar chromatographic techniques represents a niche application compared to HPLC-based methods. Due to the nature of the development process in TLC, the combination is often considered as an off-line in situ procedure rather than a truly hyphenated system. True in-line TLC tandem systems are not actually possible, as the TLC separation must be developed before the spots can be monitored. It follows that all TLC tandem instruments operate as either fraction collectors or off-line monitoring devices. Various elaborate plate extraction procedures have been developed. In all cases, TLC serves as a cleanup method.

New tank systems are also equipped with leak monitoring devices that take advantage of the double-walled construction. Leakage can be reported in real time and more accurately using these detection devices, which include water- or product-sensitive probes, or pressure detection devices if the space between the two walls is designed to remain under vacuum.
