testo 6381差壓變送器,可計算風量和可選溫濕度測量,精度±0.5%測量值,自校零功能,50-1000hPa可選量程,可選信號輸出,可選顯示幕,可輸出壓力相關單位,濕度單位和風量單位


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.
