Dwyer Instruments 616KD-A-06-V Differential Pressure Transmitter 0-20" w.c. Voltage Output

The Dwyer Instruments 616KD-A-06-V is a compact differential pressure transmitter featuring One-Touch® Digital Push-Button Calibration Technology, designed for simplicity and ease of use in HVAC and building automation applications. With a pressure range of 0 to 20 inches water column (in w.c.) and a field-selectable voltage output (0–10 V, 0–5 V, 2–10 V, or 1–5 VDC), this transmitter is well-suited for duct pressure monitoring, air handler control, variable air volume (VAV) systems, and filter condition monitoring.

Key Features:

• One-Touch® Calibration: A single push button sets both zero and span — no turn pots, no external reference pressure source, and no removal from service required
• High Accuracy: ±0.25% full-scale accuracy (616KD-A designation)
• Field-Selectable Voltage Output: 0–10 V, 0–5 V, 2–10 V, or 1–5 VDC (V option)
• Power Requirements: 10–35 VDC (3-wire) or 12–26 VAC (4-wire) for voltage output models
• Current Consumption: 24 mA max
• Process Connections: Dual-size barbed fittings to accept 1/8" or 3/16" (3 mm or 5 mm) ID rubber or vinyl tubing
• Electrical Connections: Screw-type terminal block
• Enclosure Rating: NEMA 1 (IP20), tested to UL Standard 2043 for plenum-rated applications
• Temperature Limits: 0 to 140°F (-17.8 to 60°C); Compensated Range: 20 to 122°F
• Stability: ±1% FS/year
• Thermal Effect: ±0.02% FS/°F
• Pressure Limits: 5 psig overpressure
• Agency Approvals: CE, UL Standard 2043
• Weight: 1.8 oz (51 g)
• Mounting: Vertical with pressure connections pointing down (factory calibration orientation)
• Service Media: Air and non-combustible, compatible gases

Common applications include air handlers, duct static pressure control, variable air volume systems, and differential pressure measurement across filters. The 616KD-A-06-V is an ideal choice for OEM integrators and building controls professionals seeking a reliable, compact, and easy-to-maintain transmitter.
