Description

The FirstRate FSTRD-905A utilizes Frequency Modulated Continuous Wave (FMCW) radar technology at 76-81 GHz. This high-frequency operation results in a narrow beam angle, concentrated energy, and excellent signal-to-noise ratio, enabling precise level measurement even in the presence of surface turbulence, foam, vapor, or heavy dust. Its small antenna size and integrated mounting bracket facilitate quick, non-contact installation without the need for custom fabrication.

Designed for harsh industrial settings, the sensor features a stainless steel housing and a PTFE (Teflon)-encapsulated radar antenna, providing exceptional resistance to strong acids, alkalis, and other corrosive liquids. The integrated 10-meter cable and wide 9-30V DC input voltage range offer installation flexibility and compatibility with standard industrial power supplies.

Key Features

  • 76-81 GHz FMCW Radar Technology for millimeter-level accuracy (±2mm) and a minimal 10cm blind zone.
  • Stainless Steel Housing & PTFE Antenna Seal ensures long-term durability in highly corrosive liquid applications.
  • RS485 Modbus Output enables stable, long-distance communication with industrial control and data acquisition systems.
  • Wide 9-30V DC Operating Voltage allows for direct connection to standard 12V or 24V industrial power rails.
  • Integrated 10-meter Pre-wired Cable simplifies installation and provides immediate connectivity.
  • Broad -30°C to +75°C Operating Temperature Range guarantees performance in extreme environmental conditions.
  • Narrow Beam Angle minimizes interference from tank walls, agitators, or internal structures.
  • High Immunity to environmental factors like dust, steam, pressure changes, and surface foam.

Applications

  • Continuous level monitoring in chemical storage tanks containing acids, alkalis, and other corrosive liquids.
  • Inventory management and overfill prevention in fuel, water, and process liquid tanks.
  • Level control in industrial water/wastewater treatment basins and settling ponds.
  • Bulk solid and liquid level measurement in food & beverage, pharmaceutical, and power generation facilities.
  • Interface level detection between immiscible liquids in separators and storage vessels.

Frequently Asked Questions

What is the communication protocol for the FSTRD-905A sensor?

The sensor communicates via a standard RS485 interface using the Modbus protocol. This allows for easy integration with Programmable Logic Controllers (PLCs), SCADA systems, and industrial data acquisition units over long distances with high noise immunity.

What power supply does this radar level sensor require?

The sensor operates on a wide-range DC power supply of 9 to 30 volts. This makes it compatible with common industrial 12V and 24V DC power systems without requiring an additional voltage regulator, simplifying the installation process.

Is this sensor suitable for measuring corrosive liquids like acids?

Yes, the FSTRD-905A is specifically designed for harsh environments. Its housing is made of stainless steel, and the critical radar antenna is sealed with PTFE (Teflon), providing excellent resistance to strong acids, alkalis, and other highly corrosive chemicals.

What is the minimum distance (blind zone) from the sensor where it cannot measure?

The sensor has a very short blind zone of only 10 centimeters (0.1 meters) from the antenna face. This allows for accurate measurement in small tanks or applications where the liquid level can come very close to the sensor mounting point.

How is the sensor installed on a tank?

The sensor includes an integrated mounting bracket, eliminating the need for on-site fabrication. It is designed for non-contact installation, typically mounted on a tank's top nozzle or flange. The pre-attached 10-meter cable provides direct connection to your control system.
