Function Paramters
1) Service: Liquid, gas and steam
2) Measuring range: 0~0.06 kPa to 0~40Mpa
3) Output signal: 4~20mA DC (four-wire 220V AC power supply, 0~10mA DC output for special)
4) Power supply: 12~45V DC, generally 24V DC
5) Features of loading: Relation equation of loading impedance RL and power voltage
Vs: RL < = 50(Vs-12)
6) Indicator: Pointer-type linearity indication 0~100% scale mark or LCD indicator, LED indicator.
7) Explosion proof: A. Explosion isolation d II CT6
B. Intrinsically safe ia II CT6
8)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)
9) Maximum positive shift is 500% of minimum adjusting span; Maximum negative shift is 600% of minimum adjusting span.
10) 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
11) Static pressure: 4, 10, 25, 32Mpa
12) Humidity: Relative humidity 0to 100%
13) Volume absorption: < 0.16cm3
14) Damping (phase step response): For silicone oil, generally between 0.2s and 1.67s, continuous and adjustable
