Airflow

Designed for air conditioning and ventilation applications, this differential pressure transmitter measures -100 to 100 Pa with a 4 to 20 mA analog output (4-wire, 24 V AC/DC). Additionally, a magnetic valve performs automatic zero-point adjustment for long-term accuracy. It is available with or without a display.

Measuring differential pressure across a 50 Pa to 2000 hPa range, this transmitter uses automatic zero-point adjustment for high accuracy and long-term stability. Additionally, it calculates flow velocity and volume flow and supports configurable alarm management. It suits differential pressure monitoring between rooms and drying-process control.

Measuring differential pressure from 10 Pa to 1000 hPa, this transmitter maintains positive pressure in controlled environments and calculates flow velocity from the reading. Additionally, an optional probe adds simultaneous humidity and temperature measurement, and automatic zero-point adjustment preserves accuracy. It includes self-monitoring with an early-warning alarm.

Measuring differential pressure from 10 Pa to 10 hPa, this transmitter is built in a flat, cleanroom-conform panel design for flush wall integration. Additionally, an optional probe adds simultaneous humidity and temperature measurement, and automatic zero-point adjustment preserves accuracy. It includes self-monitoring for use in operating theatres and isolation rooms.
