The high-performance differential pressure transmitter EJCDP-A is suitable to measure liquid, gas, or steam flow as well as liquid level, density, and pressure. EJCDP-A outputs a 4~20 mA DC signal corresponding to the measured differential pressure. Its highly accurate and stable sensor can also measure the static pressure which can be shown on the integral indicator or remotely monitored via HART communications. Other key features include quick response, remote set-up using communications, self-diagnostics, and optional status output for pressure high/low alarm.
It is Using differential capacitance as a 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.
● 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 0~100%
● Volume absorption: < 0.16cm3
● Damping (phase step response): For silicone oil, generally between 0.2s and1.67s,continuous and adjustable
