Dwyer Instruments DHC-006 Pressure Control
The Dwyer Instruments DHC-006 Digital Differential Pressure Controller is a high-precision instrument engineered for low-pressure HVAC automation and cleanroom monitoring. This unit features a piezoresistive sensor capable of measuring ranges up to 2.5" w.c. with an accuracy of ±1% full scale. Contractors rely on the DHC series for its versatility, as it functions as a differential pressure transmitter, a switch, and a digital gauge in a single 1/16 DIN housing. The 4-20 mA output allows for seamless integration with BMS controllers, while the dual SPST NO relays provide reliable setpoint control for filter status monitoring and VAV systems. The backlit LCD ensures clear visibility of static pressure readings in tight mechanical rooms, and the adjustable deadband prevents relay chatter in high-turbulence ductwork. Its compact design and square root extraction capabilities make it an essential component for air flow measurement and pressure-critical environments.
Key Benefits for Field Installation- Reduced Installation Footprint: The 1/16 DIN form factor displaces bulkier magnehelic gauges and separate switches, saving valuable panel space.
- Precise Setpoint Control: Digital programming eliminates the calibration drift common in mechanical differential pressure switches.
- Multi-Unit Versatility: Field-selectable engineering units including " w.c., Pa, and mm w.c. accommodate various building automation specifications.
- System Feedback: Dual relays and an isolated analog output provide simultaneous local control and remote monitoring capabilities.
How do I handle fluctuating pressure readings in ductwork?
The DHC-006 features adjustable digital damping. Increasing the averaging intervals stabilizes the readout and prevents premature relay tripping caused by system turbulence.
Can this controller be used for air flow applications?
Yes, the internal square root extraction functionality allows the unit to display and output linear flow data when connected to a pitot tube properly.
Is the DHC-006 compatible with 24V DC systems?
This model is designed for universal power compatibility, supporting 100-240 VAC or 24 VDC in specialized configurations to match your control panel voltage requirements.
