CS3701CD Online Digital Graphite Conductivity EC TDS Salinity Sensor with CE RS485

Short Description:

Designed for Pure, Boiler Feed water, Power Plant, Condensate Water.
Easy to connect to PLC, DCS, for Aquaculture and Hydroponics with CE industrial control computers, general purpose controllers, paperless recording instruments or touch screens and other third party devices.Unlike traditional electrode sensors, it uses two toroidal coils encapsulated in corrosion-resistant material such as PFA or PVDF. An alternating current in the drive coil induces a voltage in the liquid, and the receiving coil measures the resulting current, which is proportional to conductivity. This design eliminates electrode fouling and polarization, ensuring long-term stability in harsh environments. Electromagnetic sensors are ideal for measuring strong acids, alkalis, saline solutions, and wastewater. They provide a wide measurement range (e.g., 0–2000 mS/cm) and feature automatic temperature compensation. With analog and digital outputs (4-20mA, Modbus RS-485), they integrate seamlessly into industrial control systems for reliable online monitoring.
