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.
