Apex Pressure Controllers

Control from Atmosphere to Low Milli-torr Range  

Apex Pressure Controllers for vacuum applications combine pinpoint accuracy with flexibility to specify your application's parameters. Apex Pressure Controllers can be used in a number of different ways to control vacuum pressure. Vacuum sensing can be from our on-board 0-30 psi sensor to using a vacuum gauge installed on your chamber or system. Dual valve pressure control is available for closed systems. Apex Vacuum Pressure Controllers can be combined with our mass flow controllers & meters on our BB9 hub to control up to 26 devices with one computer.

Apex Vacuum Pressure Controller

The Standard Apex Pressure Controllers have pressure ranges from around 4 torr to 760 torr for vacuum applications. Pressure controllers can be designed for in-line or back pressure configurations. Set points can be given to the device through analog, digital or direct input through the control pad on the device. Various valves can be used on the pressure controller for different flow ranges. One common application is to bleed a gas into the vacuum system to maintain set pressure while the system is actively pumped. 

Apex Millitorr Pressure Controllers 0.1 Millitorr to 760 Torr

The Millitorr Apex Pressure Controllers for rough vacuum applications have pressure ranges from 0.1 Millitorr to 760 Torr. Using an external Capacitance Diaphragm Gauge (CDG), the Millitorr Pressure Controller can accurately control pressure for all of your rough vacuum applications. CDG ranges are typically 3 or 4 decades of resolution with full scale values of 1000 torr, 100 torr, 10 torr and 1 torr. The CDG is typically mounted on your system or chamber and then connected to the pressure controller connected to the gas input line. 

Apex Dual Valve Pressure Controllers 8 Torr to 760 Torr

The Dual Valve Apex Pressure Controllers have pressure ranges from 8 torr to 760 torr for vacuum applications and valves on both the inlet and exhaust. The Apex Dual Valve PC is the prefect tool for pressure control for closed systems due to its dual valve system. This system allows pressurizing as well as exhausting of your chamber or test piece while maintaining consistent pressure all with one device. A fourth sensing port is available located in the front of the device.
