testo 6381 – differential pressure transmitter with flow calculation

The testo 6381 transmitter was specially designed for monitoring differential pressure in the 10 Pa to 1,000 hPa measuring range.

In cleanroom technology, the maintenance of positive pressure prevents the entry of contaminated air. In order to keep the cleanroom conditions constant, the transmitter additionally calculates volume flow and flow velocity from the measured differential pressure.

An optional probe from the testo 6610 probe series also enables simultaneous recording of humidity and temperature with one transmitter.

A particularly outstanding feature of the Testo 6381 pressure transmitter for differential pressure is the automatic zero-point adjustment, which ensures high accuracy and long-term stability. The integrated self-monitoring and early warning function also guarantee the operator’s high system availability.
