DWYER INSTRUMENTS 616KD-05 Differential Pressure Transmitter, 1/8 Inch Hose Barb, 0 to 15 Inch WC, 4 to 20mA DC Output

The 616KD Series Differential Pressure Transmitters with One-Touch® technology are cost-effective, compact transmitters that reduce up front costs as well as expenses over the life of the product. The transmitter not only alleviates cumbersome turn pots typically found in most transmitters, but eliminate entirely the need to span the instrument during calibration. With a single digital push button, both ZERO AND SPAN are calibrated properly, nothing else is required. No additional reference pressure sources and separate calibration devices are necessary; no need to remove from service and send to a lab. All that is required of the installer or user is to let the unit sit at zero reference pressure, then push a button. That is it! The transmitter is now ready for operation. Time savings are enormous over the life of the product compared to traditional transmitters which require time to annually remove the product from service plus the additional time to actually perform a complete full-span calibration.
