Reliable and provenObserverTM

Reliable and well provenThe 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 diff erent types of Observer gas detectors, which can be equipped with universal plug-in modules for the provision of additional functions and communication protocols. The diff erent available type are: Semi Portable; Suction and Diff usion 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 notifi ed 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.

In-controlTM software makes confi guring the unit a quick and easy operation.

Portable unit PSH-WAD

Features of the WAD units

Maximum security and clear informationObviously 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 fl ow and if required the status of the pyrolyzer! Moreover, all systems permanently analyse the sensor operation.

Simple installation and confi gurationBecause of it’s modular construction the SH-WAD and TX-WAD unit can be installed progressively. For example, a JC-Box can be mounted during an early stage of the installation.

Confi guring of the WAD units is quite simple. When installing a gas sensor, parameters such as target gas, measurement range and measurement unit are all set automatically. The user only has to specify the alarm values and the desired alarm responses. This can easily be done with the In-control™ confi guration software. A laptop with this software can be connected to the RJ-45 port on the frontside of the unit.

Extensive communication possibilitiesThe SH-WAD and TX-WAD units can be used as independent detectors, but can also be part of a larger gas monitoring system. Depending on the selected confi guration, data transfer can take place via a bus line, but also via a 4-20mA signal. The Profi bus-DP module makes it very easy to link the unit to a PLC based alarm system. Such a system off ers a great deal of fl exibility and minimises installation costs.

Portable unit for emergency monitoring and temporary area monitoringPerforming maintenance tasks in a production facility often requires the presence of additional gas detection equipment. It is also possible that new or temporary installations have not yet been equipped with fi xed detection systems. In these situations the PSH-WAD provides a solution for your monitoring needs. The portable unit can also be used by emergency response teams to analyse the environment after an evacuation.

Integrated alarm handlingIn practice, alarm actions are frequently desired directly at the point of detection. Using the optional relay card, an alarm output can be made available directly inside WAD unit. In many cases this considerably reduces the amount of cabling around the system. The portable PSH-WAD can also be equipped with this relay card to enable a local alarm connection.

A suction and diffusion type WAD unit equipped with a JC-Box and relay module. Bus-line connec-tion 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 with a remote sensor adapter for the monitoring of extraction systems. The unit transmits a 4-20 mA signal to an alarm unit 16CWA (or 8CWA). The link to a SIMS-NX PC is optional.

Various options for system con� gurations

Advice, service and supportApart from the performance of the gas detector itself, advice is extremely important for an optimised safety situation. The choices of gas to be detected and the location of the sensors relative to potential source and airfl ow are critical areas which aff ect the overall safety of the system. In open dialogue with the customer, the Bionics Instrument account managers have the knowledge to fi nd the best solution for any specifi c application. In the long run, customers are better off with Bionics Instrument gas detectors – and the sound service and support that comes with them.

Sensor lifetimeSome gas detector suppliers off er their products at low prices. But the cost of the detector is not that important when performance and cost of ownership are considered. How long will the sensor of a cheap gas detector last? What gases and what range will they, in fact, detect? Most sensors ‘die’ once they have met with overconcentration of gases. Some are even sensitive to the use of IPA clean wipes, as they react to alcohol or other solvents. And what is the price of the sensor that has to be renewed? Bionics Instrument guarantees the lifetime of nearly all sensors and all pumps for fi ve years. In practice, a customer can probably use them (much) longer. During regular maintenance, twice a year, normally only the electrolyte and the membrane have to be replaced.
