Continuous frost monitor with capillary sensor

How energy efficiency is improved

Demand-controlled, large-area monitoring of system components with active capillary sensor


  • Records the lowest temperature that occurs for a length of at least 250 mm at any position along the capillary tube

  • Used on air side in ventilation and air conditioning units where protective measures must be taken against freezing

  • Active capillary sensor for measuring the lowest temperatures in the range 0…15 °C

  • Vapour-filled capillary tube and diaphragm system with inductive system of measurement

  • Setting range 1…10 °C

  • Start-up function

  • LED and 7-segment display

  • Self-monitoring of sensor line
