ZR202G Integrated type Zirconia Oxygen Analyzer

Can be operated in the field without opening the cover using optical switches.
Display:
Switch:
Output Signal: 4 to 20 mA DC, one point (maximum load resistance 550 Ω)
Digital Communication (HART): 250 to 550 Ω, depending on quantity of field devices connected
Contact Output Signal: Two points (one is fail-safe, normally open)
Contact Input Signal:
(Excluding standard gas tolerance)
(Excluding the case where the reference gas is by natural convection)
(Use oxygen of known concentration (within the measuring range) as the
zero and span calibration gases.)
±1% Maximum value of set range;
less than 0 to 25 vol%O
