Digital Push-Button Calibration Technology
The Series 616KD Differential Pressure Transmitters ±0.25, ±1, or ±2% Accuracy
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.
FEATURES/BENEFITS
• 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
• Optional1/8˝NPTprocessconnectionallowsforusewithmetalbarbedttingsor

• Optional plenum rated units meeting UL Standard 2043 are available
APPLICATIONS
• Air handlers
• Variable air volume
• Duct pressure
• Filter monitoring
