Testo 6381 Differential Pressure Transmitter

Introduction of Testo 6381

Order-Nr. 0555 6381

The Testo 6381 transmitter is specifically designed for monitoring differential pressure within the 10 Pa to 1,000 hPa range. In cleanroom technology, maintaining positive pressure is essential to prevent the ingress of contaminated air. To ensure consistent cleanroom conditions, the transmitter also calculates volume flow and flow velocity based on the measured differential pressure.

Additionally, an optional probe from the Testo 6610 series allows for the simultaneous measurement of humidity and temperature with the same transmitter. One of the standout features of the Testo 6381 is its automatic zero-point adjustment, which provides high accuracy and long-term stability. The transmitter's integrated self-monitoring and early warning function further enhance system reliability, ensuring high availability for the operator.

Testo 6381 Key Features

• Measurement of differential pressure, flow velocity, volume flow; optional: humidity and temperature
• Automatic zero-point adjustment guarantees high, temperature-independent accuracy and long-term stability
• Low measurement range up to 10 Pa ensures very high precision at lowest pressures Ethernet, relay and analog outputs allow optimum integration into individual automation systems
