Product Overview
Series B12 transmitters are loop powered instruments that transmit a 4 to 20 mA signal linearly proportional to gas concentration. The system is operated from a 24 VDC power supply, and sufficient for most monitoring applications.
Alternatively, the unit can operate at 12 VDC, with a reduced output load for applications requiring battery operation.
