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 is 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 PC
and controller to for logging data via RS232 or LAN.
Model VCpro 601 controls vacuum pressure by
opening and closing of a solenoid valve that is
plumbed in-line between the 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.
