The Apex Vacuum Pressure Controller uses the Apex Controller, a Capacitance Diaphragm Gauge on the chamber and a cable to control an input pressure entered on the Apex PC. The Apex Pressure Controller can control 3 decades below the full scale value of the CDG from 1000 torr down to 1 torr. The Capacitence Diaphragm Gauge Full Scale Ranges are 1000 torr, 100 torr, 10 torr, & 1 torr.
The Vacuum Pressure Controller is accurate to +/-0.5% of FS and repeatable to +/-0.5% of full scale.
Apex Mass Flow Controller can measure 30 gases. One gas should be specified for the primary gas calibration.
A 115V/60Hz power cable(PVPS24U) is available to power the unit.
The Apex Mass Pressure Controller can be set via the on-board display or via 0-5V, 0-10V or 4-20 mamp signals. For the end user, flows can be read and the controller set via the on-board display. FlowVision Software can be purchased for using a computer to record and graph the flows. The gas selection can also be made from the computer.
For use with a system, a 6 ft. cable(DC-61) or a 25 ft. cable(DC-251) can be purchased in the communication cable section. One end is the 9 pin Din connector to connect to the Apex MFC, while the other end are blank wires.
System consists of:
Apex Pressure Controller with quick adjustment fine resolution valve
Oerlikon Leybold Capacitence Diaphragm Gauge
Cable between the Controller and Gauge
Flow Rate- We may need to know the approximate flow rate into your system since pressure control is somewhat dependant on the size of the vessel.
Output - Output of the pressure controller can be in the form of 0-5V, 0-10V or 4-20 mAmps. Every Apex device has RS-232 capability and does not need to be specified.
Secondary Output - Second output capability. This output can be the mass flow rate, temperature, pressure or volumetric flow rate.
Special Gas Connectors - We can provide a welded VCR female fitting on the gas inlet and output of the meter.
Industrial Connector Option - Controller can be outfitted with a screw on industrial connector for more secure fit on the communications cable. Supplied with a 10 ft. industrial connector cable.
TFT Display - Add TFT Screen for easier reading in low light levels and at times when the screen is viewed at an angle.
