    At a Glance

    • Ranges: 0-0.25mbar up to 0-4.9mbar
    • Outputs: 4-20mA, 0-5Vdc, 0-10Vdc
    • Line / Common Mode Pressure: 650mbar max. (range dependent)
    • Accuracy: <±1%/FS
    • Very Low-Pressure Measurements in Dry/Dry Environments 
    • Ideal for Static Duct Pressure, HVAC, Pharmaceutical & Clean-Room Pressure Applications
    • Stainless Steel Capacitive Sensing Element
    • Robust IP65 Rated Enclosure


    The PR3202LR ultra-low range sensor accurately measures differential pressure from as little as 0-0.25mbar to an accuracy of better than ±1% of full scale. Thanks to the PR3202LRs stainless steel capacitive sensing element, the sensor requires minimal amplification which provides excellent accuracy and long-term stability.

    It is enclosed in an IP65 / NEMA 4 plastic glass-filled polycarbonate UL94v-0 case enabling it to withstand many harsh environments. Zero and span adjustments are accessible inside the case allowing for easy on-site adjustment if required.

    The PR3202LR ultra low range differential pressure sensor is designed for tiny pressure measurements of dry, non-corrosive gases in applications such as HVAC systems, clean room monitoring and over pressurisation, static duct pressure and energy management systems.

    This ultra-low range differential pressure sensor comes with 3/16″ OD barbed brass pressure connections to suit flexible hose, while electrical connection is made via a cable gland to internal screw terminals.
