High Precision Pressure Transmitter

QYB400 intelligent pressure transmitter adopts a modular design with a microprocessor as the core and ad.vanced digital isolation technology in circuit design, making the instrument highly anti-interference and stableThe built-in temperature sensor compensates the transmitter, improves measurement accuracy, reduces tem.perature drift, and has the characteristics of good long-term stability, high reliability, and strong self-diagnosiscapability.Structurally, users can easily calibrate,set and configure the transmitter through the HART communi-.cation handheld terminal.
It measuring pressure and level in pipes and tanks, electricity/city gas, pulp/paper, for furnace pressure, etc.

    Features:

    • High accuracy
    • Import high-precision monocrystalline silicon sensor chip, accuracy <±0.05%.
    • Strong load resistance
    • Double overload protection diaphragm design, single overvoltage can reach 25MPa.Excellent environmental adaptability
    • Iintelligent static pressure compensation and temperature compensation eliminate the influence of temperature, static pressure and overload on the transmitter, minimizing the comprehensive measurement error onsite.
    • Excellent long-term stability
    • Stability can be maintained at 0.1%F.S/10 years.
    • The latest one-click clearing function does not affect the electrical protection level, making it safer and faster
    • Flexible remote assistance debugging function
    • Realize remote and local parameter setting function configuration through Hart or RS485 communication andpanel buttons
