Series B12 transmitters are loop-powered instruments Transmitters are normally supplied with the sensor that transmit a 4–20 mA signal linearly proportional to close coupled to the enclosure. However, for special gas concentration. Operated from a 24 VDC power applications, the unit can be supplied with separate supply, the transmitter will drive loads up to 675 ohms sensors that can be located up to 25 feet from the — sufficient for most monitoring applications. transmitter. Sensor duct mounting adapters and Alternatively, the unit can operate at 12 VDC — with sensor flowcells can also be provided...
