The Soway PCR25P34 series is a high-performance capacitive flow switch designed for demanding industrial applications. It operates on the principle of capacitive sensing, which detects flow by monitoring changes in capacitance as fluid passes through a bypass pipe. This non-contact measurement method ensures the sensor is unaffected by liquid color, opacity, or the presence of particles, making it highly reliable for a wide range of media.

Key Features

• High-Temperature and High-Pressure Capability: Engineered for extreme conditions, the PCR25P34 series can handle media temperatures from -25°C to +120°C and withstand pressures up to 50 bar.
• Built-in Amplifier: The integrated amplifier design saves space and simplifies installation, making it suitable for compact systems.
• Wide Pipe Diameter Compatibility: Adaptable to pipe diameters of 8-11 mm or 12-26 mm, providing flexibility for various piping configurations.
• Robust Construction: Features a PEEK (Polyether Ether Ketone) sensor head and FKM (Viton) seals for excellent chemical resistance and durability in harsh environments.
• IP67 Protection: The stainless steel (304) housing is rated IP67, offering superior protection against dust and water ingress, suitable for outdoor and washdown applications.
• Versatile Output Options: Available with NPN or PNP open collector outputs, compatible with most industrial control systems.

Installation and Operation

The PCR25P34 series is designed for easy installation in bypass pipes. The sensor should be mounted so that the flow direction aligns with the arrow marked on the housing. The built-in LED indicator provides a clear visual indication of flow status, simplifying setup and troubleshooting. No moving parts ensure long-term reliability and minimal maintenance.

Applications

The PCR25P34 series is ideal for flow monitoring in various industrial sectors, including:

• Chemical and petrochemical processing (for corrosive media monitoring)
• Power generation (for cooling water and lubrication systems)
• Food and beverage industry (for hygienic applications)
• Pharmaceutical manufacturing (for clean-in-place (CIP) systems)
• Hazardous environments (for dust-proof and explosion-proof requirements)
• Industrial automation (for pump protection and filter monitoring)
