KJF-2V automatic pressure control system is designed for applications that need pressure control specifically for open-end system with in-line flow such as Vacuum Tube Furnaces. The Compact Digital Vacuum Gauge provides an RS-232 analog output of the pressure signal to pressure control unit which directly controls those two solenoid valves (a feed valve and an exhaust valve).
Complete Package includes
One Digital Pressure Guage with 1/8 to 1/4 NPT adapter
10-4 to 1000 Torr
•Two Solenoid Valves with 1/4 NPT (F) connecting ports •One pressure control unit, power cable included •Two 1/4 NPT Male-to-Male Couplers

Typical Operation Procedures for Controlling Tube Furnace Pressure
•Install feed valve (inlet) on one end of tube flange, then connect it with gas supply cylinder. •Install exhaust valve (outlet) on the other end of tube flange, then connect it to vacuum pump or gas recovery system •Install digital pressure gauge on the tube flange •Well connect the Pressure Gauge and two Solenoid Valves to Pressure Control Unit, •Power on the system by 110/220 VAC power source. •Set pressure low limit and high limit on digital pressure gauge •The pressure inside the tube chamber will be kept within a desired range
Note
•Gas flow-in/out rate can largely affect system pressure control accuracy, the minimum range of pressure control recorded by using the system shown in below is :
•+/- 100 mtorr (< 1 torr), •+/- 5 torr (1 ~ 760 torr), •Please click the picture above to see details of system setup.
