Information About FR-S01

The FR-S01 is part of the Keyence FR Series of radar level sensors optimized for short-range, high-precision liquid level measurement. It utilizes a radar-based non-contact detection system that ensures stable performance regardless of temperature, pressure, or surface conditions. Featuring a 24 VDC power supply, multiple configurable outputs, and a robust SUS304 and PTFE construction, it provides excellent chemical and mechanical resistance. With IO-Link compatibility, it supports advanced data communication and remote configuration, making it ideal for tank monitoring, fluid storage, and process automation applications.

Key Features:

  • Radar Measurement Technology: Provides non-contact, high-accuracy liquid level detection.
  • Short-Range Precision: Measuring range up to 1.5 m with 1 mm resolution for compact tanks.
  • Integrated Display: Easy-to-read interface for local monitoring and setup.
  • Smart Communication: IO-Link v1.1/COM2 compatibility for data tracking and control integration.
  • Flexible Output Options: Supports NPN/PNP open collector and 4–20 mA analog outputs.
  • Rugged Construction: SUS304 stainless steel with PTFE lens ensures chemical resistance.
  • High Environmental Protection: IP67 enclosure for resistance to dust and water ingress.
  • Wide Temperature Range: Operates from -20°C to +55°C (-4°F to +131°F).
  • Advanced Protection Circuit: Safeguarded against reverse polarity, surges, and overcurrent.
  • Fast Response: Adjustable response time from 0.4 to 10 seconds for application flexibility.

The FR-S01 delivers the reliability, durability, and precision required for liquid level monitoring and control in industrial tanks, vessels, and process systems.
