Technical details and manufacturing context for Level Sensor/Transmitter

Definition
A critical component of the Melt Surge Tank system that continuously monitors the height or volume of molten material, converting the physical level into an electrical signal for process control, safety interlocks, and inventory management.
Working Principle
Typically operates by measuring hydrostatic pressure, capacitance, ultrasonic echo time, or radar wave reflection to determine the distance from the sensor to the liquid surface, then converts this measurement into a standardized output signal (e.g., 4-20 mA, HART, Foundation Fieldbus).
Common Materials
Stainless Steel (316L), Ceramic, PTFE (Teflon)
Technical Parameters
  • Measuring range, typically from 0 to the full height of the Melt Surge Tank. (mm) Customizable
Components / BOM
  • Sensing Element/Probe
    Directly interfaces with the process medium to detect the liquid level via pressure, capacitance, or wave reflection.
    Material: Stainless Steel, Ceramic
  • Electronics Housing
    Contains the signal conditioning circuitry, microprocessor, and communication modules that convert the raw sensor data into the output signal.
    Material: Aluminum Alloy, Stainless Steel
  • Process Connection
    Provides the mechanical and pressure seal for mounting the sensor to the Melt Surge Tank (e.g., flange, threaded).
    Material: Stainless Steel
Engineering Reasoning
0-3.5 m H2O (0-34.3 kPa) with ±0.25% FS accuracy
Exceeds 4.2 m H2O (41.2 kPa) differential pressure or 150°C process temperature
Design Rationale: Diaphragm rupture due to overpressure exceeding 120% of rated span or elastomer degradation above 130°C glass transition temperature
Risk Mitigation (FMEA)
Trigger Electrolytic corrosion from chloride ions >25 ppm in process fluid
Mode: Capacitance cell short circuit causing 4-20 mA signal lock at 3.6 mA
Strategy: Hastelloy C-276 wetted parts with PTFE-coated sensing diaphragm
Trigger Vortex shedding at fluid velocity >0.8 m/s with 5 Hz structural resonance
Mode: Strain gauge fatigue fracture producing ±15% span hysteresis error
Strategy: Radial baffle plate installation and 316L stainless steel probe with 10 mm diameter
