A steam trap (thermostatic, inverted bucket, float, thermodynamic, venturi nozzle,¡¦) is a device used to discharge condensate and non-condensable gases with a negligible consumption or loss of steam. ½ºÆÀÆ®·¦(¼¸ð½ºÅÂƽ, Áõ±âº¯È¯¹öŶ, ½ºÆÀÇ÷ÎÆ®, ¼¹ö´ÙÀ̳ª¹Í, º¥Ãò¸®³ëÁñ µî)Àº º¸»ó ºñº¸»ó¿ë °¡½º¸¦ ¹æÃâÁ¶ÀýÇϴµ¥ »ç¿ëµÇ´Â ±â±¸·Î¼ ½ºÆÀÀÇ ¼Òºñ·®Àº ¹«½ÃÇÒ ¼ö ¾ø´Ù.

With the new ultrasonic vision/detection combined technology LEAKSHOOTER LKS1000 and with a special contact probe, it is possible to detect and listen to these defaults (open, closed, leak¡¦) which create ultrasonic wave due to presence of steam and condensate flow during the running cycle.

It is then possible to detect and listen to the normal condition (almost CYCLING) of the steam trap and then detects anomalies (permanent Open or Closed trap).
