The Testo 6351 differential pressure transmitter measures differential pressure, flow velocity and flow volume. The Testo 6351 has a measurement range of 50 Pa to 2000 hPa and automatic zero-point adjustment which guarantees high, temperature-independent accuracy and long-term stability. The Testo 6351 differential pressure transmitter has many features including Ethernet, relay and analog outputs to allow optimum integration into existing automation systems. A display for easy adjustments via the operating menu and an optical alarm. The 6351 is compatible with P2A software which allows for the parameterization of unit and scale, sensor adjustment, analog output adjustment and adjustment history which can all be transferred to a PC for data storage and analysis. The self-monitoring transmitters guarantee high system availability. Applications for the Testo 6351 Differential Pressure Transmitter Differential pressure monitoring between cleanrooms Differential pressure monitoring in filling processes and spray-painting systems Monitoring differential pressure, flow volume and velocity in critical air conditioning technology (VAC systems) Testo 6351 Differential Pressure Transmitter Specifications Differential Pressure Parameters Measuring Range 0 to 50 Pa0 to 100 Pa0 to 500 Pa0 to 10 hPa0 to 50 hPa0 to 100 hPa0 to 500 hPa0 to 1000 hPa0 to 2000 hPa -50 to 50 Pa-100 to 100 Pa-500 to 500 Pa-10 to 10 hPa-50 to 50 hPa-100 to 100 hPa-500 to 500 hPa-1000 to 1000 hPa-2000 to 2000 hPa Measurement Uncertainty ±0.8% of measurement range final value ±0.3 Pa Selectable Units Pa,more available Sensor Piezoresistive sensor Automatic Zero-point adjustment Via magnetic valve.
