JCDP Capacitance Differential Pressure Transmitter
It is a digital differential pressure transmitter designed for industrial pressure measurement applications . It can be configured to provide integrated solutions for a broad range of pressure and flow measurement
Using differential capacitance as detecting principle to constitute capacitance type differential pressure transmitter, inputting pressure is 0~1.2kPa to 0~10MPa, etc.
Service medium: liquid, gas and vapor.
Overpressure limit: impose 0 (absolute pressure) ~6MPa pressure on either side of the transmitter. The transmitter is not damaged. The transmitter’s operation static pressure is detailed in the models and specifications sheet
Technical Parameter
● 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
