Description

6920 Temperature Transmitter with optional Set Point Adjuster by Testo

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
