Air Differential Pressure Transmitter with 4-20mA output

Air differential pressure transmitter devices to measure very low pressures between two pressure sources. It works using a capsule bellows element and are suitable for use on clean dry gases. SPECIFICATIONS: The product shell is made of aluminum alloy, which is simple and beautiful, and easy to install; The damping filter design makes it less affected by dynamic pressure; Can be used for differential pressure, pressure and negative pressure measurement at the same time; Can be equipped with LCD display meter with low power consumption and wide temperature range; High overload and high static pressure design; Output signal, electrical connections and pressure connections are all standardized. Working power supply 15～36 VDC (calibrated voltage 24VDC) Measuring medium Non-corrosive conventional gas Measuring range Gauge pressure (G)—maximum (0～400)KPa, minimum (0～100)Pa Relative pressure (B)—(0～400)KPa, minimum (0～100)Pa Negative relative pressure (B)–(-0.1～400)KPa, minimum (-50～50)Pa Overload capacity 2 to 20 times the measuring range Long term stability Less than 0.2%FS/year, less than 0.5%FS/year Output signal (4～20)mA (two wire system) Accuracy level 0.5% Operating temperature -40～70℃ Compensation temperature -40～80℃ Stability Less than 0.3%FS/year Process connection A.
