Dwyer Series 616KD One-Touch Differential Pressure Transmitter
The Dwyer Series 616KD One-Touch Differential Pressure Transmitter is a compact, cost-effective instrument designed for precise measurement of air and compatible gases. Its standout feature is the One-Touch® digital push-button calibration technology, which simplifies zero and span adjustment with a single press—eliminating the need for cumbersome potentiometers or external calibration tools. Available with standard 4-20 mA output or optional voltage outputs (0-5 V/0-10 V), and factory-calibrated to specific ranges, it is ideal for OEM applications, HVAC systems, and industrial process monitoring where space, simplicity, and reliability are critical.
