Magnetrol TA2-A1B0-142 Thermal Dispersion Switch

Feature & Principle

It is a thermal dispersion type point level / low flow switch of Magnetrol TA2 series. It uses two RTD sensing elements, one heated and one reference. The temperature difference changes with medium coverage or flow velocity. The internal circuit converts temperature difference signal to relay switch output for alarm or interlock. It has no moving parts, good resistance to viscous, dirty medium, widely used for tank high/low level, liquid-liquid interface and minimum flow protection.
