characteristic 

• No dangerous radiation, no precautions for protection of health.
• No manipulator is necessary. The electromagnetic sensor is fastened to the mold top directly so it does not obstruct operating personnel and/or function of 
  a tube-changer in any way. It is possible to use the mold level detector signal also for automatic start of casting.
• The mold level sensor could be assembled and fully tested on the mold in the workshop to save the necessary time for mold exchange on the casting
  machine.
• Mold level detector measures true molten steel level in the mold, regardless of thickness of slag or casting powder on surface of molten steel bath.
  The detector characteristic does not depend on the steel grade.
• Sensitivity of mold level measurement and control to local meniscus instabilities is widely suppressed because the detector measures “global” mold level.
  The slab detector measures the level in the area of approx. ± 300 mm from the sensor axis. The bloom detector measures the level near two opposite
  mold plates.
• Quick time response adjustable from 0.1 s to 2.5 s.
• Low noise of the detector signal corresponds to the mold level standard deviation less than ± 0.5 mm.
• The detector does not need any manipulation or calibration before casting: AUTOSET procedure initialized automatically by PLC executes a remote zero
   setting before casting.
• Heavy duty construction of the sensor. It is manufactured from a solid block of stainless heat-resisting steel. Protection of the sensor against damage
  at short-time overflow is ensured by efficient water cooling. If damages of seals, coils, etc. occur it is practically always possible for the manufacturer to
  repair the sensor.
• Detector comprises effective auto-diagnostic systems for quick solving even prevention of most common operating troubles:
  - The permanent checking of the transition resistances of the contacts of the sensor cable and the intermediate cable to warn of possible detector failure from
     the reason of electrical connection loss.
  - The measurement of the leakage resistances in the sensor and sensor intermediate cable within the AUTOSET to warn of possible penetration of moisture.
  - The SELF-TEST procedure for quick testing of electronic part of the detector.
• The detector comprises extra hardware and firmware for:
  - Suppression of the influence of the narrow mold plates of slab or thin slab mold if the changing of the mold width during casting is applied.
  - Suppression of the influence of the vertical movement of the tundish during casting if the gap between the mold level sensor cover and the lowest
    metal part of the tundish is less than approx. 200mm but more than 150mm.
  - Suppression of the waves (swinging) of the liquid steel surface in the slab mold (if necessary).
  - Suppression of the influences of the electromagnetic brake (EMBR) or mold stirrer (MEMS) caused by the mold level sensor surrounding, especially by
    ferromagnetic coating of the mold copper plate under the sensor and mold water cooling box.
• Two versions of evaluation unit are available. Cost effective one-signal unit 1SH-D and three-signal unit 3SH-D which in addition to all functions mentioned
  above provides:
  - Beside the “global” mold level signal the signals of the local level in the areas left and right from the submerged entry nozzle (SEN) are available for
    example for prediction of the surface quality of the cast slab/bloom.
  - The possible suppression of the impact of the manipulation with metal tool or splashing by drop of liquid steel close to one (left or right) reading coil of
    the sensor.
