Product Overview

The Festo SFAW-100T-TG34-E-PNLK-PNVBA-M12 is a robust, high-performance thermal mass flow sensor engineered for accurate monitoring of compressed air and nitrogen flow rates in industrial automation systems. Designed with a wide measuring range up to 1000 L/min, this model provides reliable performance in air supply networks, energy management systems, and pneumatic machinery.

Featuring dual switching outputs, analogue signal output, and IO-Link® communication, the SFAW-100T delivers both real-time process visibility and advanced digital integration for smart factory environments. Its durable build and large digital display make it ideal for demanding industrial applications requiring continuous flow measurement and diagnostics.

Key Features

• Wide Measuring Range: Measures air and nitrogen flow rates up to 1000 L/min with high repeatability.
• Thermal Mass Flow Technology: Provides accurate and temperature-compensated readings.
• Dual Output Configuration:
  • Two switching outputs (PNP/NPN)
  • One analogue output (0–10 V / 4–20 mA / 1–5 V selectable)
• IO-Link® V1.1 Communication: Enables remote parameterisation, data logging, and predictive maintenance.
• Large Digital Display: Two-colour illuminated LCD (red/green) with configurable units and alarms.
• Bidirectional Flow Measurement: Monitors flow in both directions for flexible pneumatic layouts.
• Fast Response Time: Provides near-instantaneous flow feedback for control applications.
• Robust Build: Nickel-plated brass housing and stainless-steel sensing elements ensure long service life.
• Easy Installation: G3/4 threaded connections and M12 electrical connector for plug-and-play setup.
• Clean and Compact Design: Optimized for panel integration or direct line mounting.
