Function Parameters

● 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)</span>
● 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 0~100%
● Volume absorption : < 0.16cm3</span>
● Damping (phase step response) : For silicone oil, generally between 0.2s and1.67s, continuous and adjustable
