Description
The BRENDA series has been fitted with the DF-200 series high-performance digital mass flow controller developed in-house. This has made it possible to produce mixed gas with more accurate gas mixture ratios than previous device. The adoption of an 8-inch touch panel has also simplified mixed gas density and flow settings. The BRENDA series, which also has a full range of functions, comes standard-equipped with VNC server function, making remote operation through networks and remote control at mobile terminals through wireless access points possible.
Features
High-performance digital mass flow controller adopted
Supplying high quality mixed gas
In-house production of mixed gas at desired gas mixture ratios is possible.
Step mode
Program operation with pre-set conditions is possible
A maximum of nine steps for gas flow and time pre-settings are possible
VNC server function added
Remote operation through networks and remote control at mobile terminals through wireless access points are possible
Data logging compatible
Sampling cycles can be set to record operation status.
Registered data can be extracted via the USB port in the device.
Fitted with a touch panel
Anybody can easily set and confirm the status of gas mixture ratios while viewing the touch panel screen.
Q Various functions added
Safety function
An emergency shutoff valve has been fitted to the mixed gas exit, making it possible to cut off the gas manually with the emergency shutoff switch, and there is also an automatic shutoff function in response to alarm setting values.
Setting authority
All settings can be made into authorization settings requiring a password.
Lower and upper limit settings
Lower and upper limits can be set for flow and pressure for each line.
Ratio setting mode
It is possible to automatically calculate and control gas flow for each line by just setting gas mixture ratios and mixed gas flow
Flow integration function
Integrated gas volume can be displayed for each line. which is convenient for grasping how much is left in the cylinder.
