Advantages Of Thermal Dispersion Switches For Pump Protection
7/1/2014
Thermal dispersion switches use similar principles as thermal mass flow meters. Fluid carries heat away from the probe tip reducing the temperature difference between a heated resistance temperature detector (RTD) and a reference RTD.
