Description

The FST400-1000 operates on the magnetostrictive principle, where a current pulse sent down a waveguide interacts with a position magnet, generating a torsional strain wave. The time-of-flight of this wave is measured to determine the absolute position of the magnet with high repeatability. This non-contact method provides exceptional durability and eliminates wear-related drift.

Housed in a robust, oil-resistant outer tube, the sensor is engineered for direct integration into hydraulic and pneumatic systems. Its 4-20mA two-wire output is compatible with standard PLC analog input modules and industrial data acquisition systems, providing a linear representation of the 950-1000mm measurement range. The integrated LED indicator aids in quick operational diagnostics and fault finding.

Key Features

  • High-Precision Magnetostrictive Sensing: Delivers absolute linear position measurement with selectable accuracy of ±0.1%FS or ±0.3%FS.
  • Industrial-Grade Durability: Pressure-resistant outer tube construction with IP67 rating for protection against dust and temporary immersion.
  • Standard Industrial Interface: 4-20mA two-wire analog output ensures compatibility with PLCs, DCS, and other control systems.
  • Extended Environmental Range: Operates reliably from -40°C to +85°C, suitable for demanding industrial applications.
  • Non-Contact Measurement: Eliminates mechanical wear, ensuring long-term stability and reduced maintenance.
  • Integrated Diagnostics: LED status indicator provides immediate visual feedback for power and signal health.
  • Optimized Mechanical Design: M18x1.5 pressure port facilitates secure mounting in hydraulic/pneumatic manifolds.
  • Low Power & Thermal Drift: Engineered for efficient 24VDC operation with minimal temperature-induced measurement error.

Frequently Asked Questions

What is the wiring diagram for the 4-20mA output on this sensor?

The FST400-1000 uses a standard two-wire 4-20mA loop. Connect the positive supply terminal (24VDC+) to the sensor's power input, and connect the sensor's output terminal to the positive input of your PLC or receiver's analog input module. The negative input of your receiver and the sensor's ground/common terminal are then connected back to the 24VDC- supply to complete the loop. The current draw corresponds directly to the measured position.

How do I mount the position magnet for accurate measurement?

The included ring magnet must be mounted securely onto the moving target (e.g., a piston rod) using the provided fastening screw and non-magnetic gasket. Ensure the magnet's orientation is correct and that it moves axially along the sensor's rod without physical contact. The magnet should be positioned within the sensor's 950-1000mm stroke range, and all mounting hardware should be tightened to the specified torque to prevent slippage.

Can this sensor be used in high-pressure hydraulic systems?

Yes, the FST400-1000 is specifically designed with a pressure-resistant outer tube and an M18x1.5 threaded port for direct integration into hydraulic or pneumatic manifolds. Its robust construction and IP67 rating make it suitable for environments with oil, water spray, and high pressure. Always verify the sensor's maximum pressure rating against your specific system requirements before installation.

What is the difference between the ±0.1%FS and ±0.3%FS accuracy options?

The accuracy specification defines the maximum permissible error relative to the full scale (FS) of the 950-1000mm range. The ±0.1%FS version offers higher precision (error within ±1mm), ideal for critical control applications. The ±0.3%FS version (error within ±3mm) provides a high-value build for applications where ultimate precision is less critical. The specific accuracy of your unit will be indicated on its product certification.
