The Arthur Grillo DPC200-R is a state-of-the-art solution for measuring and controlling very small differential pressures in ventilation and air conditioning systems. Unlike standard transmitters, the "R" variant integrates powerful control capabilities, allowing it to function as a standalone PID controller or a versatile pressure switch for industrial environments.

Precision Control for Air Technology

The DPC200-R is designed to handle non-aggressive gases with high precision. It allows users to switch between several measuring ranges within a single device, providing maximum flexibility for different installation sites. The integrated PID algorithm can directly control frequency converters or dampers to maintain a constant pressure or volumetric flow rate, ensuring optimal air quality and energy efficiency.

Industrial-Grade Reliability (IP65)

Engineered for durability, the DPC200-R is housed in a robust plastic casing that meets the IP65 standard. This makes it resistant to dust ingress and low-pressure water jets, allowing it to be installed in demanding industrial areas, mechanical rooms, or rooftop air handling units. The internal piezoresistive sensing element is protected against overpressure and provides excellent long-term stability with minimal maintenance requirements.

Key Features

• Adjustable Switching Points: The two integrated relays can be programmed as independent setpoints with adjustable hysteresis, ideal for filter monitoring or fan failure alarms.
• Versatile Output Signals: Features a selectable analog output (0...10 V or 4...20 mA) that can be scaled to represent pressure or volume flow.
• Square Root Extraction: Built-in math functions allow for the direct calculation and display of volume flow when used with a Pitot tube or measuring orifice.
• User-Friendly Setup: All parameters, including damping, units (Pa, mbar, inchH2O), and control logic, are easily accessible through the front-panel menu.
• Zero-Point Calibration: Simple manual or automatic zero-point adjustment ensures accuracy over the entire lifespan of the device.

Typical Applications

• Cleanroom Technology: Maintaining positive or negative pressure barriers to prevent contamination.
• HVAC Systems: Precise control of supply and exhaust air fans in commercial buildings.
• Filter Monitoring: Signaling a required filter change when the differential pressure across the filter exceeds the set limit.
• Industrial Ventilation: Monitoring dust extraction systems and industrial drying processes.
• Volume Flow Control: Measuring air velocity in ducts using differential pressure-based calculations.
