3700 Электромагнитный датчик электропроводности

Principle of Operation

• The 3700E Series encapsulated electrodeless conductivity sensors induce a current in a closed loop of solution and then measure the magnitude of the current to determine the conductivity of the solution. The conductivity sensor drives Coil A, which induces an alternating current in the solution; Coil B detects the magnitude of the induced current, which is proportional to the conductivity of the solution. The conductivity sensor processes this signal and displays the corresponding reading.

• Problems such as polarization, oil fouling, and contamination will not affect the performance of electrodeless conductivity sensors. The 3700E Series conductivity sensors feature automatic temperature compensation and can be applied to solutions with conductivity up to 2000 mS/cm and temperatures ranging from 0 to 200°C.

• The 3700E Series electrodeless conductivity sensors are available in four different water-resistant materials, offering wide applicability;

• Suitable measuring media for conductivity sensors of different materials: see attached table
