Description
The Testo 6381 differential pressure transmitter measures differential pressure, flow velocity, flow volume and is available with an optional humidity and temperature sensor port. The automatic zero-point adjustment guarantees high, temperature-independent accuracy and long-term stability. The Testo 6381 has a low measurement range up to 10 Pa, which ensures very high precision at the lowest pressures.
The Testo 6381 differential pressure transmitter has many features including robust metal housing for protection against tough ambient conditions. Ethernet, relay and analog outputs allow optimum integration into existing automation systems and the display allows for easy adjustments via the operating menu and it also features an optical alarm. The 6381 is compatible with P2A software which allows for 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.
Applications for the Testo 6381 Differential Pressure Transmitter
- Differential pressure monitoring between cleanrooms
- Monitoring drying processes
- Differential pressure monitoring in filling processes and spray-painting systems
