Technical indicators
Accuracy leve:Level 1.0
Conditions of use:1.Ambient temperature:-20℃~+60℃2.Medium temperature:0-70 ℃;-20℃~+70℃3.Atmospheric pressure:8
Electrical performance indexof volume corrector:
1.Working power supply:internal power supply:3.6VDC lithium battery,external power
supply:(9~28)VDC,ripple ≤50mV,when connected to the external power supply,the
internal power supply is automatically disconnected,and the whole machine is powered by the external power supply.
2.Power consumption of the whole machine:Internal power supply:the average power
consumpton is ≤0.8mW,a 2#lithium battery can be used continuously for more than two years,and when it is in a dormant state,the power consumption is ≤0.2mW.Externa power
supply:the power consumption of the whole machine is ≤1W.EVE dedicated power supply: When in the sleep state,the power consumption is ≤0.05mW.
3.Input signal:flow signal:(0～5)kHz pulse signal,Vpp=2.5V.Temperature signal:The resistance signal output by the temperature sensor.Pressure signal:The digital signal output by the pressure sensor.
