Main functions and Characteristics
Transforms the measured signal to a voltage&κόμμα; after HCNR200 linearity photodiode transforms to DC output which has extremely good linear relations with the measured signal&κόμμα; uses the computer aided designed&κόμμα; the principle is simply&κόμμα; circuitry designed concisely&κόμμα; reliability is highly and installment is conveniently&περίοδος;
Notice
Operating environment should not have the electric dust and gas of corrosive metal and destruction insulation existence&κόμμα; the altitude should less than 2&κόμμα;500 μέτρα&περίοδος;
The Zero and CAL have been adjusted when products left factory&περίοδος; Please don’t adjust at will&περίοδος;
