The new E+E Elektronik AVS701 – high-precision air and gas flow measurement

In today’s fast-paced industrial environments, the need for precise, reliable, and durable air and gas velocity measurement is more critical than ever. Whether you’re monitoring cleanroom airflow in pharmaceutical production or ensuring optimal conditions in metal additive manufacturing, accuracy and longevity directly impact process reliability and operational costs. The AVS701 air and gas velocity sensor is engineered to meet these demands, offering unmatched performance, robust construction, and simplified installation for a wide range of industrial applications.

Key Benefits of the AVS701 Air and Gas Velocity Sensor

The AVS701 sensor is designed with industrial users in mind, addressing common challenges such as harsh environmental conditions, fluctuating ambient pressures, and the need for rapid deployment. Its advanced features deliver both operational excellence and significant cost savings.

• Exceptional Durability: The AVS701’s high-end ceramic sensing element is protected by a stainless steel probe head and specialized coating. This construction ensures stable measurement results even under corrosive or extreme conditions and extends the sensor’s lifespan up to 20 times longer than conventional alternatives.
• Highly Accurate Measurements: With a measurement range from 0 to 40 m/s (0 to 8,000 ft/min) and temperature tolerance from -40 to +140 °C (-40 °F to 284 °F), the AVS701 delivers precise data across diverse applications.
• Process Reliability: Integration of a process gas library enables adaptation to various gases (including air, nitrogen, CO₂, and argon), ensuring correct calibration for each use case.
• Ambient Pressure Compensation: An optional external pressure sensor compensates for variations in ambient pressure, supporting consistent results regardless of environmental changes.
• Simplified Installation: The AVS701 features integrated sensor positioning for quick setup—reducing installation times by up to 60% compared to traditional sensors.
• Reduced Lifecycle Costs: Robust design minimizes downtime due to maintenance or replacement, resulting in lower total cost of ownership.

Typical Applications

Thanks to its versatility and resilience, the AVS701 is suited for a broad spectrum of industrial processes where air or gas flow must be monitored with high precision. Below are some representative use cases:

Technical Specifications

The robust technical capabilities of the AVS701 make it an ideal choice for demanding environments. Below is an overview of its key specifications:

Installation Guidelines

Proper installation ensures measurement accuracy and sensor longevity. The AVS701 offers flexible mounting options but some best practices should be followed:

• Install the probe in the middle of the duct at a position with regular (non-turbulent) flow.
• Avoid turbulent areas immediately after fans, bends, junctions, or diameter changes; place at least six duct diameters downstream from such disturbances when possible.
• The preferred position is after a filter or before diffusers where air velocity is highest.

Summary

The AVS701 air and gas velocity sensor redefines performance standards in industrial measurement technology. Its combination of accuracy, robustness, simple installation, and adaptability makes it an indispensable tool across many sectors—from pharmaceutical production lines to advanced manufacturing environments like metal additive printing. With proven durability even under harsh conditions—and efficiency gains that translate directly into cost savings—the AVS701 stands out as the premier choice for demanding applications.
