The Cordis CPC series is a closed-loop electronic pressure controller designed for precise, non-pulsing control of clean, dry, non-corrosive gases in applications requiring steady downstream pressure. It is available in card (CPC-C), housed (CPC-H), and CE-approved housed (CPC-E) variants, all featuring dual normally-closed proportional valves, 1/8" NPT or G1/8 porting, and a 15 to 24 VDC power requirement. The controller operates within a vacuum to 150 psig (10.3 bar) range with ±0.25% full scale accuracy, ≤5 mV resolution, and <20 ms typical response time. Wetted components include nitrile elastomers, anodized aluminum manifold, polyamide sensor, and nickel-plated brass valves. It supports 0 to 10 VDC, 4 to 20 mA, or 3.3 VDC serial command signals and includes power (red) and command mode (blue) LED indicators. Operating temperature ranges from 32 to 120°F (0 to 49°C). All variants offer IP65-rated housing as an option and are calibrated to NIST traceable standards.
Precise, linear digital pressure control within a closed-loop system with ultra high resolution and repeatability.
The Cordis is a revolutionary microcontroller primed for escape velocity from a proportional control market that has grown stagnant. Built with the highest quality Clippard EVP and DVP proportional valves at its heart, the Cordis is designed to outperform the competition in every way. With unparalleled performance and flexibility not possible with current analog proportional controllers, the Cordis makes everything from calibration to sensor variety acceptance to future development opportunities more accessible and less complicated. The future of proportional pressure control has arrived, and it's digital.
Features & Benefits
Known for reliability, innovation, and focus on miniature pneumatics, Clippard's new Cordis electronic pressure controls (EPC) utilize the proven EVP and DVP lines of electronic proportional valves allowing for steady, repeatable downstream pressure as demand or processes change. The result, a precise linear pressure control within a closed-loop system with ultra high resolution and repeatability.
The Cordis uses a microcontroller, integrated pressure sensor, and two Clippard proportional valves. The inlet valve is connected to the moderately regulated supply pressure and the exhaust valve is connected to a port that vents excess pressure to atmosphere. Once a command is increased, the inlet valve opens up to allow supply pressure to pass over the sensor element which provides an active feedback for this microcontroller to satisfy the set point in the process. If at any point the sensor detects a value higher than the set point, the exhaust valve will modulate open to vent off the excess pressure to maintain a stable and accurate control pressure in the process.
The Cordis pressure regulators are adaptable to a variety of sensors that can close the loop around not only pressure, but vacuum or flow.
