Conductivity sensor SE 204

Precision and Versatility in Conductivity Measurements

The SE 204 Conductivity Sensor by Knick is engineered to deliver exceptional performance in a variety of applications requiring conductivity measurements. With its sophisticated 4-electrode design and durable epoxy body, this sensor is well-suited for environments where medium to high conductivity is prevalent. The integration of four graphite electrodes allows for enhanced measurement accuracy and stability, making it a reliable choice for users seeking precise data in their processes.

One of the standout features of the SE 204 is its built-in temperature detector, which utilizes a 30 kΩ NTC thermistor. This capability is crucial for accurately compensating conductivity readings for temperature variations, which can significantly impact measurement results. The sensor operates effectively within a temperature range of -5 to 100 °C (23 to 212 °F), accommodating various operational conditions commonly encountered in industrial applications.

Designed with user convenience in mind, the SE 204 boasts a minimum immersion depth of 36 mm, making it adaptable for use in tanks, reservoirs, and other fluid storage systems. Its compact dimensions (body length of 120 mm and diameter of 15.3 mm) ensure compatibility with various installation setups, allowing for easy integration into existing systems.

The robust construction of the SE 204 further enhances its performance in challenging environments. The epoxy body is designed to withstand the rigors of industrial applications, while the POM isolator and Viton gasket ensure durability and chemical resistance. With a pressure tolerance of up to 2 bar (relative), this sensor is built to perform reliably even in demanding conditions.

In terms of electrical specifications, the SE 204 is capable of measuring conductivity levels ranging from 1 µS/cm to 500 mS/cm, providing a wide measurement scope to accommodate different fluid types. The cell constant is specified at 0.475 cm^-1 with an accuracy of ± 1.5%, allowing for highly accurate conductivity readings. Depending on the measuring range, the resolution will vary, providing the flexibility necessary for specific applications.

Knick’s commitment to quality and performance is evident in the SE 204, making it an excellent choice for water and wastewater treatment facilities, chemical processing plants, and other industrial applications. Its reliable performance, coupled with an integrated temperature compensation feature, ensures users receive accurate and actionable data critical for maintaining system efficiency and compliance with regulatory standards.

The SE 204 Conductivity Sensor offers a blend of precision, durability, and versatility, making it an invaluable tool for professionals in need of reliable conductivity measurements in various media. Its design and features empower users to optimize their processes while ensuring high-quality performance across a broad spectrum of applications.
