Pressure Controllers

Clippard released its Cordis CP1 pressure controller, which provides precise linear pressure control within a closed-loop system, the company says. Utilizing the company’s EVP and DVP proportional valve, the line also incorporates a microcontroller and an internal pressure sensor. The inlet valve is connected to the moderately regulated supply pressure. Once a command is increased, the proportional valve opens up to allow supply pressure to pass over the sensor element which provides an active feedback for the microcontroller to satisfy the set point in the process. If at any point the sensor detects a value higher than the set point, the proportional valve closes and allows process to consume the remaining downstream pressure. With a typical Flow of 2.7 to 65 l/min (±10% @ 100 psig), the CP1 features a response time of <20 ms, depending on application and an accuracy of ±0.25% of full scale. www.clippard.com
