Series 616KD Differential Pressure Transmitter

One-Touch® Digital Push-Button Calibration Technology, ±0.25, ±1, or ±2% Accuracy

General Information :

The SERIES 616KD Differential Pressure Transmitters with One-Touch® Digital Push- Button Calibration Technology 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.
