Heavy duty in line flow and temperature controller

Posted on 24 Jul 2009

The programming functions are secured by an access code which can also be programmed.


SDN 552/4 devices monitor medium temperatures between 0 and 90 °C. They are suited for flow rates between 10 and 100 l/min. The sensors are based on the thermodynamic principle. They have no moving parts which protrude into the medium. They withstand pressures up to 20 bar and feature IP 65 protection. The sensors are fitted directly into pipes via a G3/4 thread. They are connected via an M12 plug connector.
