Product Description
Keyence FD-SA1NA / FD-SP1 Coriolis Flow Sensor
The Keyence FD-SA1NA / FD-SP1 is a highly accurate Coriolis Flow Sensor system from the industry-leading FD-S series, designed for precise fluid measurement and monitoring. This complete system includes the FD-SP1 sensor unit, featuring a 1.0L specification, paired with the highly responsive FD-SA1NA amplifier unit. Operating on a standard 24V DC (Class 2) power supply, it offers versatile system integration through multiple output configurations, including discrete control outputs and a 4-20mA analog output. Please note that this sensor is designed exclusively for clean liquids; to ensure optimal performance and longevity, piping must be cleaned after use and fluids containing solid particles must be avoided to prevent clogging.
