Differential Pressure Transmitter – testo 6383


The differential pressure transmitter testo 6383 was developed specially for monitoring low differential pressures in the measuring range from 10 Pa to 10 hPa. In cleanroom technology, the maintenance of positive pressure prevents the entry of contaminated air in critical zones. Thanks to an optional internal or external probe from the probe series 6610, the additional recording of humidity and temperature with one instrument is also possible.The testo 6383 is particularly outstanding thanks to the automatic zero-point adjustment which ensures high accuracy and long-term stability.
The integrated self-monitoring and early warning function also guarantees the operator high system availability. Measurement of differential pressure; optional: humidity and temperature.

Flat housing allows flush surface integration in the cleanroom wall. Ethernet, relay and analog outputs allow optimum integration into individual automation systems. Self-monitoring of the transmitter and early warning function guarantee high system availability. The P2A software for parameterization, adjustment and analysis saves time and costs in commissioning and maintenance. Configurable alarm management with adjustable response delay and alarm acknowledgement.


• Flat housing enables flush surface integration in the cleanroom wall
• Low measuring range from 10 Pa ensures very high precision at the lowest pressures
• Pressure transmitter for measuring differential pressure, as an option: humidity and temperature
• Automatic zero-point adjustment guarantees high temperature-independent accuracy and long-term stability

Delivery Scope

testo 6383 differential pressure transmitter with cleanroom-compliant panel design, optional humidity/temperature recording, selectable measuring range between 10 Pa and 10 hPa, selectable signal outputs and optional display (depending on the configuration).
