    PWTB Series Wet Pressure Sensors

    The PWTB Series Wet Differential Pressure Sensors provide reliable, accurate measurement for controlling and monitoring liquid, gas, and vapor based systems.

    Overview
    The PWTB Series wet differential pressure sensors provide reliable, accurate measurement for a variety of applications including:
    - Demand measurement in HVAC systems for pump speed control and local monitoring
    - CW/HW system differential pressure
    - Chiller/boiler differential pressure
    - Process control systems
    - Flow measurement of gases, vapors, and liquids compatible with 316L SST
    - System leak detection

    Features & Benefits:
    • Up to five selectable ranges plus high resolution mode for lower pressures.
    • User friendly LCD displays in PSID or kPa.
    • Absolute mode outputs absolute value of difference.
    • Port swap corrects plumbing errors.
    • NEMA 4X rated enclosure
    • Uni/bi-directional modes.
    • Test mode: Forces full-scale output.
    • Over range icon warning.
    • Switch selectable outputs: 2-wire 4-20mA, 3-wire 0-5V or 0-10V.
    • High reliability withstandard integrated snubbers protect sensing elements from water hammer damage.
    • Reduced plumbing complexity and cost with remote mounted transmitter and wired pressure transducers.
    • No bypass required for installation as sensors can be installed in tees or elbows for simple air bleeding.
    • Pre-wired plenum and armored cable versions minimize wiring issues.
