Overview

The EE680 is a precision flow and temperature sensor optimized for measuring normalized air velocity and temperature in laminar flow environments. It is designed with GMP compliance, making it ideal for cleanrooms and safety workbenches in pharmaceutical, life sciences, and microelectronics industries.

Key Features and Specifications

• Measurement Principle: Hot-film anemometer with an E+E thin-film sensor element.
• Measurement Range: Air velocity 0 to 2 m/s; temperature -20 to +70 °C.
• Accuracy: Velocity ±(0.5% of measured value + 0.05 m/s) from 0.1 to 2 m/s at 23 °C and 1013 mbar; temperature ±0.5 °C at airflow ≥ 0.45 m/s.
• Response Time: Typical t90 between 1.5 and 40 seconds, adjustable via configuration software.
• Angle Dependency: Less than 3% error for flow angles within ±10°.
• Outputs: Selectable analog voltage (0-5 V, 0-10 V) or current (0-20 mA, 4-20 mA), or digital RS485 with Modbus RTU protocol.
• Power Supply: 24 V DC ±20%, <30 mA typical consumption.
• Housing and Connectors: Stainless steel (1.4404) housing with M12 stainless steel 5-pin connector; IP65 rated.

Design and Construction

• Available in straight (T15) and 90° angled (T29) probe versions with various lengths (200 mm, 300 mm).
• GMP-compliant design facilitates easy cleaning and sterilization.
• Sensor element protected by proprietary E+E sensor coating, enhancing durability and resistance to aggressive cleaning agents including H2O2 sterilization.
• Integrated LED ring provides real-time visual indication of laminar flow status and sensor condition.
• Mounting options include stainless steel flanges for secure installation.

Calibration and Certification

• Calibration traceable to International System of Units (SI) via accredited laboratories.
• Two calibration levels offered: National Metrological Institute (NMI)-level calibration by the designated Austrian institute and ISO/IEC 17025 accredited calibration.
• ISO 9001 calibration certificates available, documenting comparison against high-quality reference devices (non-accredited).
• Calibration certificates and detailed information accessible online.

Configuration and Software

• Device configuration and adjustment facilitated by free PCS10 Product Configuration Software and optional Modbus configuration adapter.
• Measurement output type and scaling can be adjusted post-installation.
• Compatible with E+E Sigma 05 modular sensor platform for plug-and-play operation with optional display and multiple sensor integration.

Technical Data Summary

Installation and Accessories
