            ◇ Good stability, stability: 0.25%60 months
             
            Contact diaphragm material is optional. Mortgage cast aluminum alloy shell
             
            ◇ Small (2.4kg) stainless steel flange, easy to install
             
            ◇ The process is compatible with other products to achieve the best measurement
             
            ◇ Standard 4-20mA with HART protocol
            Application: liquid, gas and steam.
             
            Signal output: Two-wire system 4 ~ 20mA isolated DC signal overlay HART digital signal output, can choose linear or square output maximum output current does not exceed 22mA.
             
            Power supply: DC 12 ~ 45V; HART corresponded when offered
             
            Electric voltage range: 15.5 ~ 45VDC; The general operating voltage is 24VDC.
             
            Load range: HART communication, the resistance in the power loop is more than 250 euros, power supply voltage is more than 15.5 volts.
             
            Communication distance: the wire diameter of the connecting wire is greater than 0.6mm, and the communication distance is about 1500 meters.
             
            Display: smart LCD backlight 5-digit and half-digit display; Zero and range migration: the lower limit of the measuring range shall not be lower than the lower limit of the large measuring range, and the upper limit shall not exceed the upper limit of the maximum measuring range, that is, the working range shall not exceed the limit of the sensor. The zero and range can be set at any corresponding point between 4-20mA.
             
            Zero pressure fine-tuning: with F3 key or code potentiometer knob, to correct the transmitter installation position change or zero drift caused by the error, the pressure of the transmitter is adjusted to zero pressure value.
             
            Damping value: Electronic damping adjustable range 0~32 seconds.
             
            Fault alarm: When the self-diagnostic program detects a fault, the analog output is higher than 20.8mA or lower than 3.9mA.
             
            Temperature compensation: the computer collects temperature data and sends it to the transmitter for temperature compensation.
             
            Temperature indicator: indicates the ambient temperature of the site where the transmitter works.
             
            Operating temperature: electronic circuit: -40~+85℃, with LCD LCD display: -30~+80℃ :
             
            Sensitive element (filled with silicone oil) : -40~+104℃
             
            Sensitive element (filled with inert oil) : -18~+71℃
             
            Safety protection: AND circuit protection design, anti-static shock, surge current, overload protection function is powerful.
            Differential pressure transmitter is widely used in various process automatic control environment, involving water conservancy and hydropower, railway traffic, intelligent building, production automatic control, aviation, aerospace, automotive medical equipment, HVAC and other fields of differential pressure, differential pressure, liquid level, flow control, etc.
