美國Dwyer差壓表送器（替代原616C-2）Series 616KD

Differential Pressure Transmitter

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

TheSERIES 616KDDifferential Pressure Transmitters with One-Touch廬 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.
