2-Wire Gas Transmitter
Modelo: B12
2-Wire Gas Transmitter
Series B12 transmitters are loop-powered instruments that transmit a 4?20 mA signal linearly proportional to gas concentration
Transmitters 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.
