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 a 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.

• Simple calibration push-button sets back zero and span, saving time installing and over the service life
• Cost effective and compact device suitable for OEM applications where space, simplicity, and value are key
• Ranges and accuracy selection cover a wide range of applications minimizing components and determining standardizing on design
