Anleitung Zusammenfassung


Hazardous Gas Detection Systems used in a wide variety of industries, including chemical/petrochemical, wastewater treatment, transportation and oil and gas industries. .. FieldServer Protocol Translator/Gateways and ProtoCessor protocol coprocessors manufactured and sold by the FieldServer Technologies division of Sierra Monitor provide the interoperability desired in the process control and building automation industries. .. Telecom Site Management Products used by most telecommunications companies nationwide to monitor, manage and control HVAC, safety and security in remote environmental enclosures. Sierra Monitor is an industry leader in its fields with a long lists of “Firsts” including: .. First to utilize a microprocessor based controller for area safety monitoring .. First to use digital two-way communication between the controller and the sensor for improved diagnostics, easy one-person calibration and multiplexing configuration .. First to use Modbus serial communication to enable the hazardous gas detection system to link to the plant-wide Distributed Control Systems .. First to provide a browser based graphical interface to a hazardous gas detection system .. First to provide the building automation industry with a universal protocol gateway supported by an extensive library of drivers for open systems and legacy devices; .. First to provide the telecommunications industry with a comprehensive facilities environment controller .. First to provide a protocol coprocessor for OEM use to enable the manufacturer’s product to meet the communications needs of its customer Hazardous Gas Detection 02gas detection Hazardous gas and flame monitoring are an integral part of programs designed to maintain personnel safety and protect the plant and the environment. There are three major categories of hazardous gases: ......Combustible gases - posing a risk to personnel and facilities through fire or explosion ......Toxic gases -creating both immediate and long term risk to personnel ......Oxygen displacing gases - depleting workers’ oxygen supply in confined spaces The gas and flame monitoring system required for a specific application depends upon the scope of the hazardous gas risk. Important factors in determination of level of protection needed include: .. Identify the hazards .. Assess risk of hazardous event .. Comply with laws and insurance requirements .. Consider liability and financial risks .. Develop and implement a strategy of comprehensive event response and prudent risk management For applications where the risk is minor, a simple gas monitor, such as the Model 20X or 200X, interfacing with a panel that sounds an alarm when the concentration reaches the setpoint may meet the need. Applications involving a higher risk generally require continuous output of gas concentration from gas sensor modules such as the analog gas sensor modules, to a display, printer or other indicating/control device. Sierra Monitor has the experience and the products to meet any level of gas monitoring necessary to meet the user’s safety requirements. For more complex or larger applications, a comprehensive gas risk management system including smart sensors provide a range of features necessary to meet this higher level of risk. The Sentry system and the IT series sensors provide the user the intelligent data handling, ease of installation, comprehensive alarm logic, low operating costs and reliable proven performance demanded by today’s instrumentation and safety professionals. 03sentry 03sentry Sentry Gas Risk Management System Sentry is a comprehensive, stand-alone gas monitoring system that can also be easily integrated into PLC or DCS systems. This feature-rich area safety monitoring system can be configured to meet the user’s specific needs. Even the basic Sentry system provides the user with multiplexed wiring for reduced installation costs; two-way digital signal between the sensor and controller for one-person, non-intrusive calibration; extensive diagnostics and user- friendly menu-driven display and common alarms. Building upon this comprehensive package the user can construct a system that can include 4-20 mA input, individual and zone relays, battery backup, interface to other non- Sentry devices, WebBrowser output and interface to other systems utilizing Modbus or most other common process control and building automation networks. .. User Configurable -to meet specific application needs .. Reliability – FM performance approval, TUV safety approval, continuous diagnostics and EMI/RFI filtering .. Cost Effective - multiplexing wiring for lower installation costs and minimal maintenance requirements .. Versatile - options include battery backup , graphical user interface, 4-20 mA for interface to foreign devices, analog output and multiple protocol digital output .. User Simplicity - single person, auto-adjusting non-intrusive calibration, automatic recognition of sensor types and browser...
