The Welch Model VCpro 601 vacuum controllermeasures and displays vacuum pressure bothgraphically and digitally. The vacuum pressure canbe 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 suchas distillation and vacuum drying. Full flexibility andrepeatability is achieved easily via a programmablemode with pressure over time defined by the user.
The durable, chemically resistant sensor built intothe VCpro 601 vacuum controller is a ceramicthick film hybrid. The sensor reading is gasindependent and gives an absolute pressure. Directcommunication can be maintained between PCand controller to for logging data via RS232 or LAN.
Model VCpro 601 controls vacuum pressure byopening and closing of a solenoid valve that isplumbed in-line between the vacuum pump andthe system being evacuated. The solenoid valve isattached to the controller. This model will controlvacuum pressure in your system using different typesof vacuum sources such as diaphragm pumps astypically used in small rotary evaporator applications.Our application experts can assist you choosing theright solution.
