2.3.3 General Performance
NOTES: ※1 : CE mark compliant models apply only to DC powered, non-explosionproof specifications.
※2 : For transmission length of output signal, see sec. 5.7 "Output Signal and Power Terminal ldentification".
※3 : If signal cable length exceeds 200 meters, consult the factory.
※4 : This configuration meets the requirements for explosionproof certified system approved for the sensor unit and
transmitter combined.
※5 : This configuration meets the requirements for explosionproof certified equipment approved on the transmitter
alone (valid only for use in combination with high temperature service sensor except for CN003).
※6 : This explosionproof configuration applies only to remotely located models.
※7 : Bell 202 signal is superimposed over anaog output 1 (when combined with Smart Communication Unit "Link Top").
※8 : Flow signals below 0.3% of the maximum allowable flowrate is cut off.
※9 : If voltage pulse is selected, analog output is not available.
※10 : Of error outputs, "auto zero in progress" status output can be set up.
※ : Insulation resistance and dielectric strength tests are unacceptable.
