The Series 616KD Differential Pressure Transmitters ±0.25, ±1 or 2%
Accuracy are designed for simplicity, making them the ideal choice for
installers and maintenance professionals. These instruments not only
alleviate cumbersome turn pots typically found in most transmitters, but
eliminate entirely the need to span the instruments during calibration.
With single digital push button, both ZERO AND SPAN are calibrated
properly, nothing else is required. No additional reference pressure
sources or separate calibration devices are necessary.
