Remote-Sensing Controller
The PC3-Series senses and controls the pressure at a point in the system outside of the pressure
controller itself. All PC-Series controllers can be ordered with an additional NPT port that connects
to the pressure sensor in the device. The pressure sensor is isolated from the flow path within the
device. The PCD3-Series is used for closed volumes.

Integrated Vacuum Controllers (IVC)
IVC and IVCD devices are used in applications where precise control of vacuum is required, and are available in 10 TorrA, 100
TorrA, or 1000 TorrA sensors. The IVC and IVCD-Series are similar to the PC and PCD absolute pressure controllers in functionality
and in the navigation menus available on the screen.
Integration of the vacuum sensor, control valve, and PID algorithm in a single device eliminates the need for an external vacuum
sensor and throttle valve in your system. These devices can have SAE ports, compression ports, VCR®-compatible fittings, or
VCO®-compatible fittings. Process port sizes may change depending on the valve on your device.
