ATi’s B12 2-Wire Gas Detectors are loop-powered instruments that transmit a 4-20 mA signal linearly proportional to gas concentration. Operated from a 24 VDC power supply, the transmitter will drive loads up to 675 ohms, sufficient for most monitoring applications. Alternatively, the unit can operate at 12 VDC with reduced output load for applications requiring battery operation.
These detectors are normally supplied with the sensor close coupled to the enclosure. However, for special applications, the unit can be supplied with separate sensors that can be located up to 25 feet from the transmitter. Sensor duct mounting adapters and sensor flowcells can also be provided for specific applications. Contact ATi with details of any special requirements.
