Fieldbus interface and integrated alarm handling Reliable and well proven The Observer range gas detectors have become the standard safety solutions for many production facilities and research centres. They are not only used in cleanrooms but also very useful in many other hazardous environments. There are basically four different types of Observer gas detectors, which can be equipped with universal plug-in modules for the provision of additional functions and communication protocols. The different available type are: Semi Portable; Suction and Diffusion type. Either standard or in a IP65 enclosure for humid and dirty environments. All units comply with the most stringent quality standards and are extremely reliable. With the integrated self diagnostics functions you are quickly notified on any possible disruption. In-Control Software will provide access to additional information about any changes in the status of the unit. By using an overall data-acquisition and monitoring system like SIMS-NX it is even possible to monitor the status of all detectors real-time. In this way there will never be a lack of clarity or information in case of an event. Bionics Instrument • Modular design. • Suction, diffusion and portable configurations. • Large VF display. • Integrated alarm handling and optional relay outputs. • Plug-in modules for connection to Profibus-DP and SIMS networks. • Interface for local programming and alarm acknowledgement. • Complete system diagnostics. • Records trend and history data. • IP65 protection available.

Features of the WAD units Maximum security and clear information Obviously the presence of gas must be detected accurately whilst the gas sensor should be selective and preferably 100% stable! It is also important to understand that gas detection is a dynamic process - a process of gas transport and chemical and electrochemical reactions in which continuous control is essential. Managing this process requires continuous monitoring of the ow and if required the status of the pyrolyzer! Moreover, all systems permanently analyse the sensor operation. Simple installation and conguration Because...

Various options for system configurations 1 A suction and diffusion type WAD unit linked to a PLC alarm system. Both units are equipped with a JC-Box for communication purposes. Communication is by Profibus-DP. The PLC provides the alarm output contacts. SIMS-NX software is used to collect and display the data generated by the system. A suction and diffusion type WAD unit equipped with a JC-Box and relay module. Bus-line connection to a SIMS-NX PC or stand alone operation. Alarm actions are initiated directly from the WAD units. A diffusion type WAD unit. The diffusion type unit is shown...
