GasSens Modular Gas Detector, is a flexible component system providing a variety of options to meet individual gas detection and alarm requirements. From chemical and petrochemical plants to food processors, the GasSens modular gas detection system can be applied to the simplest or most complex gas detection application. Economical and low maintenance, this system is your best choice for reliable leak detection.
GasSens modular gas detection systems consist of individual modules that can be located where required. Sensor/transmitters, located in the area where gas leakage or buildup might occur, provide the basic measurement for the system. Sensor transmitters are available in either NEMA 4X or explosion-proof versions and can be supplied with ATI’s exclusive Auto-Test automatic sensor testing system, greatly reducing operator testing requirements.
Receiver modules provide the electronic brains for the detection and alarm system. Each compact module includes a digital display of gas concentration, isolated analog output, and 4 relay outputs. Receivers may be located up to 1000 feet from sensor/transmitters for remote indication, or can provide local control functions such as valve shutoff while transmitting a 4-20 mA signal to remote displays or data loggers.
Universal power supply modules provide DC power to receivers. The power supply is housed in a compact module similar to the receiver, and will accept inputs from 85 to 265 volts, AC or DC, without adjustment. The power supply also provides a power failure relay and charging for an optional battery back-up unit.
Receiver modules provide an interface between the detection system and external alarming and data logging requirements. One module is used with each sensor/transmitter and includes a variety of features:
GasSens gas detection systems employ electrochemical sensors developed and manufactured by ATI. Expertise in electrochemistry and sensor design provides the foundation for leak detection systems that perform continuously with minimal maintenance. Sensors are rated for ambient temperatures from -25° to +50°C, allowing both indoor and outdoor applications. Excellent zero stability and high sensitivity and selectivity combine to make ATI sensors the best available on the market today.
Gas sensors are closely coupled to a digital transmitter for excellent noise immunity and the ability to transmit long distances using unshielded cable. The transmitter is powered from the receiver module and uses a unique cur- rent pulse position technique to send information to the receiver over a two wire connection. The receiver connection is not polarity sensitive, virtually eliminating the possibility of incorrect transmitter wiring. Sensor/transmitters can be located up to 1000 feet from receiver modules.
Sensor/transmitters are housed in shielded NEMA 4X enclosures for use in almost any industrial environment and are designed to meet intrinsic safety standards. An explosion-proof version of the transmitter is also available for applications where this type of protection is preferred. Combustible gas transmitters are always explosion-proof.
A major expense in gas detection systems is the cost of regular testing to ensure that sensors are responding. This requires a technician to inspect sensors weekly and apply a small amount of gas manually to check response. ATI has developed a unique system to reduce this maintenance requirement.
Available on most ATI digital sensor/transmitters is an option called “Auto-Test.” This option consists of an electrochemical gas generator closely coupled to the sensor. Every 24 hours, the receiver automatically activates the generator, producing a small amount of gas that diffuses into the sensor, just as it would if a gas leak occurred. The microcomputer in the receiver analyzes the output of the transmitter to determine that the sensor is responding normally. When proper sensor response is detected, the generator is turned off and the system goes back to normal operation. If no sensor response is detected, the TROUBLE light on the receiver will flash and the trouble relay will activate. During testing, alarm relays are inhibited so that external alarms are not activated.
The Auto-Test feature ensures that each sensor is regularly tested with gas. Premature sensor failure or blockage of the sensor membrane is quickly detected. In addition, self-testing will alert maintenance personnel when a sensor has reached the end of its useful life. Since sensors normally last any- where from 12 months to over 3 years, this feature allows users to determine when sensor replacement is needed
To meet the needs of users throughout the world, ATI has developed a compact universal power supply in a DIN rail module similar to the receiver. The power supply will accept any AC or DC input from 85 to 265 volts, without adjustment. No jumper changes or selection switches are required, and large variations in input voltage do not affect power supply operation. This power supply is suitable for operation of one or two receiver modules.
The power supply provides three 12 VDC output connections, two of which are designated for receiver module connection. A third connection is provided to automatically charge the optional external battery back-up system. The power supply module is protected by a fuse conveniently located in a removable holder accessible from outside the module. For external power failure indication, the power supply contains a SPDT relay. The relay is normally energized, and de-energizes on power failure.
Battery back-up systems are used in gas detection applications to ensure that detectors remain operable, even when AC power fails. ATI offers a separate battery back-up unit that maintains power to detection equipment in the event of a power interruption. The battery back-up system consists of a rechargeable sealed lead acid battery housed in a NEMA 4X enclosure. An electronic circuit attached to the battery controls the charging rate and will disconnect the battery from the system if the battery voltage drops to a level where battery damage might occur. Charging is provided by the power supply module.
Battery back-up units will operate a single point detector for a minimum of 12 hours and an average of 24 hours. Two point systems will be maintained for 6 hours minimum and an average of 12 hours. The actual battery back-up time depends on whether the LED display is operated in high intensity mode and whether relays are in fail-safe mode (normally energized).
A weatherproof piezoelectric audible horn is available for all gas detectors. The horn operates from 12 VDC supplied by the power supply module and can be activated from single or multiple receiver modules. The horn mounts easily in one of the enclosure knockouts, and produces an 85 dB signal for local alarming.
A 12 VDC strobe is available for enhanced visual alarm indication. The strobe uses a xenon lamp with a bright 1/2-million CP flash firing 70 times/minute. Strobe housing is weatherproof lexan with red lens, and mounts to 1/2″ conduit.
A variety of NEMA 4X enclosures are available to house receiver and power supply modules. ATI offers standard enclosures to house up to 6 modules, and can supply large enclosures for systems requiring more points of detection. System integrators can use standard 35 mm DIN rail mounting modules in their own enclosure.
Single Module Enclosure: Houses a single receiver module for use in DC powered applications where the user supplies the DC power to the system.
Two Module Enclosure: Houses two receivers or one receiver and one power supply. Normally used for single point AC powered detectors.
Three Module Enclosure: Accommodates two receivers and power supply or three receivers. Used mainly for two point detection systems.
Six Module Enclosure: Suitable for two power supplies and four receivers or six receivers. This enclosure is used primarily for four point gas detection systems.
Modular Gas Detector Special Enclosures: Custom enclosures are available to handle systems of any size. We (WJF Instrumentation) can assist with system designs for larger applications.
