FUNCTION PARAMETERS â–²Service: liquid, gas and steam
â–²Measuring range : 0~0.*6 kPa to 0~*0Mpa
â–²Output signal : 4~*0mA DC (four-wire **0V AC power supply, 0~*0mA DC output for special)
â–²Power supply : *2~*5V DC, generally *4V DC
â–²Features of loading: relation equation of loading impedance RL and power voltage
           Vs: RL <= *0(Vs**2)
â–²Indicator : pointer-type linearity indication 0~**0% scale mark or LCD indicator, LED indicator.
â–²Explosion proof : a. explosion isolation  dIIBT4
              b. intrinsically safe iaIICT6
â–²Positive and negative shifts : after positive and negative shifts of zero absolute values of upper-and-lower-limit values of span and measuring range not exceed **0% of upper limit of measuring range.( smart type : turn down ratio *0:1)
Maximum positive shift is **0% of minimum adjusting span; maximum negative shift is **0% of minimum adjusting span.
â–²Temperature range: amplifier operation temperature range: **9 ~ **3C
 (LT type: **5 ~ **0C); measuring component of fill silicone oil: **0 ~ ***4C
 flange type transmitter fill hi-temperature silicone oil: **0 ~ ***5C normal silicone oil: **0 ~ ***9C
â–²Static pressure : 4, *0, *5, *2Mpa
â–²Humidity : relative humidity 0~**0%
â–²Volume absorption : < 0.*6cm3
    â–²Damping (phase step response) : For silicone oil, generally between 0.2s and1.*7s, continuous and adjustable
