The Series 616K differential pressure transmitter is designed for building automation applications such as air handlers, duct pressure and filter monitoring. The transmitter not only alleviates cumbersome turn pots typically found in most transmitters, but eliminates the need to span the instrument during calibration. With a single digital pushbutton, both zero and span are calibrated properly. No additional reference pressure sources and separate calibration devices are necessary; no need to remove from service and send to the lab. Available models include ranges from 1-inch water-column to 10 inches water-column.
