● Wetted parts are available in polypropylene, PVDF, PEEK or PFA Teflon, etc.
● Standard 20-foot integrated cable
The 3700E series packaged electrodeless sensor induces a current in the closed loop of the solution, and then calculates the conductivity of the solution by measuring the current. The conductivity analyzer drives coil A and 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 analyzer processes this signal and displays the corresponding reading.
Problems such as polarization, oil contamination and pollution will not affect the performance of electrodeless sensors. All 3700E series sensors can be used in solutions with a conductivity of up to 2000mS / cm. The temperature range is between 0 ~ 200 ℃, automatic temperature compensation.
The 3700E series electrodeless sensors have four different water-resistant materials, which are widely applicable;
