Dwyer Instruments DHC-006 Digihelic Differential Pressure Controller 0-2.5" WC

The Dwyer DHC-006 Digihelic Differential Pressure Controller is a 3-in-1 instrument combining a digital display gauge, control relay switches, and a transmitter with both current and voltage outputs in a compact 5-inch diameter housing. This unit operates within a range of 2.5 inches of water column, making it ideal for low-pressure applications in HVAC systems, cleanrooms, and industrial environments.

Key Features:

• Achieves 1.5% or better accuracy on extremely low ranges, and 0.5% accuracy for ranges at or above 1 in w.c.
• Includes 2 SPDT control relays with adjustable deadbands, rated at 1A @ 30 VAC/VDC
• NEMA 4X (IP66) rated enclosure with backlit LCD display and LED setpoint indicators
• Scalable 4-20 mA, selectable voltage process outputs, and selectable Modbus or BACnet communication
• Reads in several commonly used engineering units with optional unidirectional or bidirectional ranges
• Field calibration capability for easy accuracy maintenance
• Can be mounted in any orientation with polycarbonate housing construction
• Fast 400ms response time with 12-28 VDC or 12-28 VAC power operation

This innovative 3-in-1 design reduces the need for several instruments, saving inventory, installation time, and cost. Programming is simple using the built-in menu system, providing versatile functionality for pressure, velocity, and volumetric flow measurement applications. Suitable for air and non-combustible gases with low power consumption of 3 VA max.
