The Dwyer Instruments DH-007 Digihelic® Differential Pressure Controller is a multi-functional powerhouse engineered to maximize performance in air and non-combustible gas monitoring. By housing a digital display gauge, independent control relays, and a current output transmitter in a compact panel-mount frame, it offers comprehensive control system integration without the bulk or cost of multiple pieces of hardware.

Featuring a clear 4-digit LCD display paired with vivid LED indicators for instant relay status visibility, the DH-007 provides real-time tracking for crucial processes. Users can configure up to 5 simplified programming menus to establish security levels, manage peak/valley data tracking, apply digital damping for unstable process dynamics, and adjust the dual 8A SPDT relays. With built-in Modbus® RTU RS485 communication, the unit seamlessly transfers system data straight to building automation and industrial SCADA platforms.

3-in-1 Advanced Functionality: Consolidates a digital display gauge, two control relay switches, and a current output transmitter into a single 1/8 DIN unit to minimize installation space, time, and inventory costs.
High-Precision Accuracy: Delivers an exceptional full-scale accuracy of ±0.5% at 77°F (25°C), including hysteresis and repeatability.
Versatile Measurement Modes: Selectable operation modes for pressure, velocity, or volumetric flow across multiple engineering units (in w.c., mm w.c., Pa, kPa, psi, mbar, etc.).
Flexible Dual Control Relays: Equipped with two SPDT control relays featuring adjustable deadbands and configurable set point/alarm logic.
Industry Standard Output: Includes a scalable 4-20 mA DC process output with square root normalization in flow modes to track actual flow curves accurately.
Robust Enclosure & Protections: Designed with a secure menu programming architecture to prevent unauthorized adjustments and a rugged face rated for NEMA 4X / IP66 washdown environments.
