Testo 6381 - differential pressure transmitter with flow calculation

SKU 0555 6381

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 guarantees the operator high system availability.
testo 6381 pressure transmitter for differential pressure – the applications

  • Differential pressure monitoring between rooms; optional: simultaneous measurement of ambient temperature and humidity
  • Monitoring drying processes
  • Differential pressure measurement in filling processes and spray-painting systems

Automatic zero-point adjustment guarantees high temperature-independent accuracy and long-term stability

Low measuring range from 10 Pa ensures very high precision at the lowest pressures

Pressure transmitter for differential pressure, flow velocity and volume flow, as an option: humidity and temperature

Configurable alarm management with adjustable response delay and alarm acknowledgement

The testo 6381 pressure transmitter for differential pressure offers the advantage of being able to calculate volume flow and flow velocity as well. With an optional probe, the transmitter also enables temperature and humidity measurements.
