Systemair PCA-2 1000D2 - Pressure controller with O.D compensation

Pressure sensor and pressure controller for measuring and controlling differential pressure and volume flow. Sensor-control module with differential pressure sensors in proven ceramic-cantilever technology for climate and cleanroom application. The pressure range goes from 0...1000 Pa (0...4.0 in.wg), four measuring ranges are programmable. Function when the pressure at the “Plus”- connection exceeds the pressure at the “Minus”- connection. Depending on the programmed Mode the device can be used as sensor or as a control module for pressure or volume flow.
