Product catalog summary

Overview: The EE355 is a compact dew point sensor capable of measuring temperatures down to -60 °C (-76 °F) at pressures up to 80 bar (1,160 psi). It provides data on dew point temperature (Td), frost point temperature (Tf), and volume concentration (Wv), making it suitable for monitoring compressed air networks and industrial drying processes.

Functionality and Reliability: The sensor features a robust stainless steel enclosure and a wettable sensing element, ensuring high performance in challenging environments. It offers excellent long-term stability and resistance to pollutants, reducing maintenance needs.

Measurement Performance: The EE355 boasts a measurement accuracy of ±2 °C (±3.6 °F) Td, achieved through an auto-calibration procedure. It has a response time of less than 5 minutes for significant temperature changes.

Outputs: The sensor provides both analogue (4-20 mA) and digital (RS485 with Modbus RTU protocol) outputs, facilitating integration into existing systems. The analogue output has a wide scaling range.

User Configurability: Configuration and adjustment are possible using the free PCS10 Product Configuration Software and an adapter cable, which is sold separately.

Features: The sensor includes an inspection certificate according to DIN EN 10204-3.1, IP65 protection rating, and various process connections. It supports a wide range of operating conditions, including temperatures from -40 to +70 °C and pressures up to 80 bar.

Calibration Certificates: The EE355 can be provided with internationally recognized calibration certificates, including those traceable to the International System of Units (SI) and ISO 9001 standards.

Technical Data: The sensor measures dew point temperature with a range of -60 to +60 °C and volume concentration from 20 to 200,000 ppm. It operates with a power supply of 18-28 V DC and has a current consumption of less than 20 mA during normal measurement.

Sampling Cells: Various sampling cells are available for different pressure ranges, allowing easy installation and adjustment of the sensor in different systems.

Ordering Information: The datasheet provides detailed ordering codes for different configurations and accessories, including process connections and output settings.

Contact Information: E+E Elektronik provides contact details for its headquarters in Austria and subsidiaries in several countries, including China, France, Germany, India, Italy, Korea, and the USA.
