The KEYENCE FD-EPH8 is a compact dual flow and pressure sensor head for 8 mm plastic tubing with one-touch fittings, purpose-built for compressed air and inert gas monitoring in industrial automation. It provides reliable, simultaneous measurement to support leak detection, performance tuning and energy-saving initiatives in pneumatic systems and process lines.

Based on a time difference transmission method, the FD-EPH8 offers 100 L/min full-scale flow measurement with fine resolution down to 0.01 L/min and a fast 2.5 ms response. Accuracy is specified at ±(2.0% of reading + 1.0% of F.S.) with overall ±2.0% of F.S. The sensor handles air, nitrogen, argon and other non-corrosive gases from -10 to +60°C and covers a pressure range of -100 kPa to +0.75 MPa (flow is not measured between -100 and -50 kPa). At 20°C, through-flow capacity reaches up to 700 L/min depending on line pressure, and the IP65 construction ensures dependable operation under vibration and shock in production environments.

Engineered with robust wetted materials such as PBT and nickel-plated brass and compatible with one-touch tubing, the FD-EPH8 integrates quickly into OEM and retrofit projects, making it a practical choice for pneumatic monitoring and non-corrosive gas applications while minimizing installation time, and it is backed by a 1-year warranty for added assurance in continuous operation.
