CONTROL
UNIT FROM
TBM
Control unit is the converter for
EMF O2 of the
sensors with Zirconia electro-chemical
cell which can measure Cell EMF
by controlling the sensor to have
fixed temperature and can display
temperature and O2 concentration.
Also
as the inside function, the user
can get the analog output in each
ranges. And it has selectable 2
points of high-low alarms.
