Dwyer Instruments 616KX-100-110-IN Differential Pressure Transmitter 1.0% FSO Accuracy

The Dwyer Instruments Series 616KX Differential Pressure Transmitter (MPN: 616KX-100-110-IN) is a compact, field-configurable transmitter designed for measuring differential pressure in air and non-combustible compatible gas applications. This model features ±1.0% FSO accuracy and a pressure range of 0–10 in w.c., making it well suited for HVAC, building automation, and industrial process monitoring.

As Dwyer's smallest differential pressure transmitter, the 616KX series prioritizes ease of installation and long-term serviceability. The One-Touch® Digital Push-Button Calibration technology is edge-mounted for convenient access in any mounting orientation, eliminating the need for complex tooling during setup or recalibration.

Key Features:

• ±1.0% FSO Accuracy — suitable for a broad range of monitoring and control applications
• One-Touch® Push-Button Zero Calibration — edge-mounted for easy field access in all mounting configurations
• Field-Selectable Output Signals — supports 4–20 mA (2-wire) and voltage output options (0–5, 0–10, 1–5, 2–10 VDC)
• Power Supply: 10–35 VDC / 12–26 VAC
• Temperature Limits: -4°F to 159°F (-20°C to 70°C)
• Stability: <±1% FSO per year
• Service Media: Air and non-combustible compatible gases
• Molded housing accommodates three sizes of both imperial and metric process connections
• Optional 1/8 in NPT or BSPT threaded process connection models available
• Unidirectional or bidirectional sensing capability
• NIST calibration available

The 616KX-100-110-IN is a direct replacement for the Dwyer 616KD and 616KD-LR series transmitters. Its compact footprint and flexible output configuration make it an excellent choice for OEM integration, building management systems, filter monitoring, and clean room pressure control.
