Component Specifications

Definition
A precision industrial sensor designed to measure and monitor the height of molten metal in real-time within furnaces, ladles, and casting systems. It ensures optimal metal level control to prevent overflow, maintain consistent casting quality, and enhance operational safety in high-temperature metal processing environments.
Working Principle
Operates primarily on non-contact measurement principles such as radar, laser, or ultrasonic technologies to detect the surface level of molten metal. Some variants use contact methods with refractory probes. The sensor emits signals that reflect off the metal surface, calculating distance based on time-of-flight or phase shift, providing continuous, accurate level data to the control system.
Materials
High-temperature resistant materials: alumina or zirconia ceramic housing, stainless steel (316L) or Inconel alloy body, refractory-coated sensing elements, and fiber-optic or shielded cables rated for >1500°C.
Technical Parameters
  • Accuracy ±2 mm
  • Power Supply 24 VDC
  • Output Signal 4-20 mA, HART, or digital (Modbus/Profibus)
  • Response Time <1 second
  • Measurement Range 0-5 meters
  • Protection Rating IP67/NEMA 4X
  • Temperature Range Up to 1600°C
Standards
ISO 13584, DIN 19266, IEC 61508

Frequently Asked Questions

What is the typical lifespan of a molten metal level sensor?

With proper maintenance, 2-5 years depending on operating temperature, exposure to slag, and thermal cycling frequency.

How does the sensor handle slag or dross on the metal surface?

Advanced signal processing filters out interference from surface impurities, and some models include automatic cleaning cycles or use frequencies that penetrate thin slag layers.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
