Critical Technical Advantages
-
Hygienic Design Compliance: The DTT35 features specialized materials and surface finishes designed to prevent bacterial growth and withstand rigorous cleaning protocols. It is compatible with a variety of hygienic process connections, such as Tri-Clamp and dairy couplings.
-
Dual-Function Monitoring: This device is capable of monitoring both flow and temperature. Users can select a configuration with two switch outputs (for example, to signal low flow and high temperature) or one switch output paired with a 4 to 20 mA analog output.
-
Optimized Flow Range: The switch is highly sensitive in the range of 0.03 to 3 m/s (0.1 to 9.84 ft/s), making it perfect for detecting subtle changes in flow that indicate filter clogging or pump inefficiency.
-
Flexible Installation: To accommodate the diverse layouts of sanitary skids, the top housing section can be rotated 310°. This, combined with a rotatable digital display, ensures that flow and temperature values are always visible to operators, regardless of pipe orientation.
-
Zero Pressure Loss: The thermal dispersion principle allows for a sensor probe that is minimally invasive. It provides reliable switching with practically no pressure drop, maintaining the energy efficiency of the liquid delivery system.
-
Simple Configuration and Storage: Through FieldCare software, settings can be quickly defined and saved. This allows for rapid setup of multiple switches across a production line and ensures that configuration data is always backed up for maintenance.
