Nevertheless, there are some aspects which will preserve a certain field of application for flameproof apparatus  

The following examples of remote monitoring and controlling equipment may make clear what has been said above. A remote station with a 18.1 TFT colour display in a flameproof housing is shown in Fig. 6.120. This station

Solid-state microprocessor based these are more sensitive and accurate. They can be made digital to be connected to a computer for remote monitoring and control of the process that the motor is driving. 

Computerized controls allow remote monitoring and control of temperatures, pressures, liquid levels, and fluid flows at three separate locations in the plant. Computer keyboards allow an operator to electronically perform precise processing adjustments from any of the three strategic plant locations. 

Among the most significant features of the ARO unit are its ability to be remotely monitored and controlled, and its ability to automatically call for help, both accomplished through a modem and telephone connection. These features allow for rapid diagnosis and service response. 

The instrumentation and control system was built for remote monitoring and control capability. Sensor outputs were visually observed as well as recorded. A 1-in. linear potentiometer was used to measure shaft position and a 6-in. linear potentiometer was used to follow shaft excursions during rapid cycling. When platform instead of shaft drive was used, platform position was determined by multiplying the measured travel time by a known...

Telemetry system is part of the monitoring, which is used for remote monitoring and controlling district heat network devices. It enables observation of individual elements and objects district heating network in on-line mode. Heat sources, heat exchanger stations and heat chamber are connected to the system. The system allows to control parameters at every point of the city and control of operations carried out currently in the network. It sends periodic inquiries about their status to the devices in the node. It also accepts alarm messages and collects historical information about the node work. Connection of nodes provides transmission equipment through a wired network and the GSM... 

A Central Control Station Represents a data collection center used to remotely monitor and control the area of interest. It typically plays two roles First, it collects data from the mobile robots and the WSN to obtain an updated system status (robot locations, sensor events, etc.). Second, it remotely controls and commands the robots and the WSN, based on the available information. 

Monitoring and control of the production process will be performed by a combination of instrumentation and control equipment plus manual involvement. The level of sophistication of the systems can vary considerably. For example, monitoring well performance can be done in a simple fashion by sending a man to write down and report the tubing head pressures of producing wells on a daily basis, or at the other extreme by using computer assisted operations (CAO) which uses a remote computer-based system to control production on a well by well basis with no physical presence at the wellhead. 

Since the relay is connected in the saine way as a meter is, it can read, calculate, and display all the desired operating paraineters such as, V, , f p.f, kVAr, kW, and kVA as well as kWh, kVArh and maximum demand. The relay can be connected to a computer and transmit all such data to a remote station for further monitoring and control. 

Remote Controlling. X-rays are harmful to humans. Nobody is allowed to enter the experimental hutch during experiments with X-rays. If observation and control is important, the experiment is observed by a system of TV-cameras and TV-monitors and controlled remotely by a second scientist.

The main held testing application areas are routine air, soil and water monitoring, pollution control and measurements taken directly at sources of contamination, at remote environmental locations and in hostile or dangerous territory. The emphasis with held devices is often on monitoring and control rather than reaction. A well-accepted dehnition for a held-portable device in terms of environmental applications is that ... 

CP systems are increasingly being provided with data loggers and telephone modem cormections for remote sensing and control from a computer in the office of the responsible party. Remote control allows frequent monitoring without actually visiting the structure. 

The main steam isolation system consists of the Main Steam Isolation Valves and their associated controls and instrumentation. The Main Steam Isolation Valves are remotely operated valves designed to either fail closed or be guaranteed to close upon receipt of a Main Steam Isolation Signal. The Main Steam Isolation Valves can be monitored and controlled locally and in the control room.
