About Dwyer 616KD-02 Differential Pressure Transmitter

Dwyer 616KD-02 Differential Pressure Transmitter (616KD-02)

Dwyer 616KD-A-02, Series 616KD Differential Pressure Transmitter, 0-3" w.c., +/- 0.25% FS, 4-20 mA

One-Touch Digital Push-Button Calibration Technology

The SERIES 61 6KD 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.

Fast, Accurate Differential Pressure Measurement

Designed for air and compatible gases, the Dwyer 616KD-02 delivers reliable pressure readings with a rapid response time of under 5 milliseconds. Its 1% full-scale accuracy ensures dependable monitoring in industrial environments such as HVAC systems, cleanrooms, and filter status applications. The LCD digital display simplifies onsite readings for quick analysis.


Simple Installation and Calibration

Installation is user-friendly thanks to the compact design, mounting bracket, and clear installation manual. With push-button adjustment for both zero and span, calibrating the transmitter is straightforward, minimizing downtime and maintenance complexity. Dual hose barb connections and 1/8 NPT female threads support flexible tubing arrangements.


Durable Construction for Harsh Industrial Settings

Encased in an ABS plastic housing with an IP54 rating, the Dwyer 616KD-02 resists dust and water splashes, making it ideal for robust industrial uses. Its electronic processing and silicon seal material help ensure longevity and steady operation across a wide temperature range, both in use and storage.
