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.
