Ghe PSD differential pressure sensors have two pressure connections with ceramic measuring cells to detect different pressures, from which the difference is formed. As a result of the pressure acting on the measuring cells, a signal that is proportional to the pressure is generated and electronically processed internally. Depending on the sensor variant, either switching or analog signals are available.All PSD variants have IO‑Link.The PSD sensors operate in various positive pressure ranges up to a differential of 250 bar.The connection with higher pressure can be configured via the menu (4igh‑Site‑Switch).
