Function Paramters

• Service: liquid, gas and steam

• 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 DC

• Features 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 CT6

              b. intrinsically safe ia II CT6

• Positive 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)

• 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 ~ +104C

 flange type transmitter fill hi-temperature silicone oil: -20 ~ +315C normal silicone oil: -40 ~ +149C

• Static pressure:4,10,25,32Mpa

• Humidity:relative humidity 0to 100%

• Volume absorption:<0.16cm3

• Damping (phase step response):For silicone oil, generally between 0.2s and 1.67s, continuous and adjustable
