pid controllers
WITH DIFFERENTIAL PRESSURE OR AIRFLOW TRANSMITTER
DPT-CTRL
DPT-Ctrl is a multifunctional PID controller with differential pressure or air flow transmitter. It enables controlling constant pressure or flow of fans, VAV systems or dampers. When controlling flow, it is possible to select a fan manufacturer or a common measuring probe that has a K-value.
USAGE & APPLICATIONS
DPT-Ctrl can be used to control air flow or constant pressure in applications where it is important to keep a constant vacuum or a steady air flow, such as vacuuming units in renovation sites that keep a constant negative pressure so that impurities do not spread to other spaces.
