VCpro 601 Automated Vacuum Controllers

The Welch Model VCpro 601 vacuum controller measures and displays vacuum pressure both graphically and digitally. The vacuum pressure can be controlled from 1100-1 mbar (825 to 0.75 Torr). Controlling the pressure can be done in real-time. In addition, a timed ramp function allowing raising & lowering pressure is built in for applications such as distillation and vacuum drying. Full flexibility and repeatability are achieved easily via a programmable mode with pressure over time defined by the user.

The durable, chemically resistant sensor built into the VCpro 601 vacuum controller is a ceramic thick film hybrid. The sensor reading is gas-independent and gives an absolute pressure. Direct communication can be maintained between the PC and controller for logging data via RS232 or LAN.

Model VCpro 601 controls vacuum pressure by opening and closing a solenoid valve that is plumbed in-line between the laboratory vacuum pump and the system being evacuated. The solenoid valve is attached to the controller. This model will control vacuum pressure in your system using different types of vacuum sources, such as diaphragm pumps, as typically used in small rotary evaporator applications. Our application experts can assist you in choosing the right solution.
