Proportional valve oxygen concentration controller
Proportional valve oxygen concentration
controller has self-determining function, which realizes auto-intelligent
determining PID control parameters, reducing user’s workload on debugging. The
controller is in small size which is convenient for setting up in the present
devices.
Proportional valve oxygen concentration
controller main features:
1.With the buttons and OLED display screen,
users could set parameters on the controller easily;
2.It can connect with the computer by RS232/RS485
serial port carried by the controller to upload the test data and control
output to the computer in real time. The received data can be observed,
analyzed and saved by the matched software, and the parameters of the
instrument can also be set flexibly by it;
3.When connected with oxygen analyzer and
other media analyzer, the input signal of the controller varies, and it can be
used with the present analyzer to upgrade and reconfigure the devices;
4.When the controller is using the output
signal from the original analyzer, it can provide a set of output signal in the
same type of the input signal simultaneously, not occupying any present
resources;
5.When receiving the signal from the
analyzer, the unit can shift automatically, which is: when the concentration is
less than 1%, the unit can shift to ppm display automatically to improve the
control accuracy;
6.High control accuracy, small fluctuation
and conspicuous gas saving amount;
