Differenzdrucktransmitter

Smart Differential Pressure Transmitter Measuring range : 0 0.06 kPa to 0 40Mpa Output signal : 4 20mA DC (four-wire 220V AC power supply, 0 10mA DC output for special)Power supply : 12 45V DC, generally 24V DCFeatures of loading: relation equation of loading impedance RL and power voltage Vs: RL <= 50(Vs-12)Indicator : pointer-type linearity indication 0 100% scale mark or LCD indicator, LED indicator.Explosion proof : a. explosion isolation d II BT4 b. intrinsically safe ia II CT6Positive 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 100% of upper limit of measuring range.( smart type : turn down ratio 20:1,40:1,100:1)Maximum positive shift is 500% of minimum adjusting span; maximum negative shift is 600% of minimum adjusting span.Temperature range: amplifier operation temperature range: -29 +93C(LT type: -25 +70C); measuring component of fill silicone oil: -40 +104Cflange type transmitter fill hi-temperature silicone oil: -20 +315C normal silicone oil: -40 +149C Static pressure : 4, 10, 25, 32Mpa Humidity : relative humidity 0 100% Volume absorption : < 0.16cm3 Damping (phase step response) : For silicone oil, generally between 0.2s and1.67s, continuous and adjustable
