NC
valve design.
The
special designed bypass can achieve the
goal to control large flow with a small
body. The design of MC-4400 can expand the
flow from 10sccm to 5L. And MC-1200 can
expand the flow form 20L to 100L.
The
value of CF of the sensor is set by a Dip-switch
to match with any kind of gas.
Because
the temperature of the sensor is quite low（the
temperature is about 300C higher
then ambient temperature), the quality of
the gas intended to be measured will not
be changed. Meanwhile, the controller has
an advantage for long term safety.
Maintain
a constant difference between the sensor
temperature and the ambient temperature,
so the controller will not be affected by
the ambient temperature. Operating temperature
can be achieved.
Clean
(clean
structure).
Except
for 0-5VDC, 0-5mA can also be used to input
the setting of flow. Switching the DIP switch
can select the input method. Besides, because
a differential input is available, there
is no variation error at common earth.
The
response speed is a two-step design including
FAST and SLOW. The speed is switched by
a DIP switch.
Three
control modes are available for the control
under 2%.
The
filter element with metallic enclosure can
avoid high frequency noise.
The
signal connector is a D05 type 8pin female
connector.
