The OI-6000 Explosion-Proof Ambient Air Gas Detector from Otis Instruments is a wired power assembly that uses an electrochemical, infrared, catalytic bead, or photoionization detection (PID) sensor element to detect a variety toxic gases in potentially hazardous environments.
The OI-6000 features three non-intrusive magnetic switches (MENU, ADD and SUB) that allow for complete system configuration, regular calibration, and product maintenance to be performed in the field without opening the enclosure, therefore maintaining its explosion-proof rating in a wide temperature range. Non-intrusive interface is made possible by use of the Otis Magnetic Tool included in the purchase of the device.
Class I, Division 1, Groups C and D certified, as well as rated for Zone 1, Group IIB environments, the OI-6000 continuously monitors the gas level of the surrounding environment and reports once a minute; the reporting rate increases to once every five seconds when the detected gas is above the background gas set-point.
The device contains a power draw of two watts maximum with an operating voltage of 12 to 35 VDC through a 3-wire power connection. Wired analog output options include: 4-20 mA (3-wire), fault terminal, and optional 2 dry-contact relays with replaceable 4-amp fuses. Other output options include RS-485 digital, and GEN II MHz radio or GEN II 2.4 GHz radio.
The OI-6000 also boasts a 102×64 transflective (sunlight readable), graphical LCD screen with a white LED backlight, so the present concentration of gas being detected by the sensor assembly can be seen clearly to the user.
The sensor assembly can be purchased with an optional OI-501 Remote Sensor Kit (5-pin), allowing remote monitoring of applications within hazardous locations for use up to 250 feet from the controller.
Protected by an aluminum device enclosure and stainless steel sensor housing, the OI-6000 can be used within hazardous environments to provide operators with around-the-clock surveillance and monitoring capabilities and ensure the safety of personnel.
