Testo 6351 Differential Pressure Transmitter
Description
Description
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)
