What it is

The Broag sensor tube, part number 85000027, is a 1/2 inch sensor pocket used on Broag Commercial P 520 series boilers. It houses the temperature sensor and holds it in contact with the water circuit so the boiler control can read system temperature accurately. It is a serviceable component on commercial Broag appliances.

Signs this part needs replacing

  • Temperature readings from the boiler control are erratic, drifting or implausible
  • The boiler short-cycles or modulates poorly because the sensor is not reading the water temperature correctly
  • Overheat lockouts or temperature-related fault codes appear on the appliance
  • Visible corrosion, pitting or leakage around the sensor pocket
  • The sensor no longer seats correctly in the tube, giving a loose or intermittent contact

Before you order

  • Confirm your appliance model against the fit list above, as the tube is listed for specific P 520 variants
  • Check the thread size and depth of the existing sensor tube match the 1/2 inch fitting
  • Confirm whether the fault lies with the tube or with the sensor itself before ordering
  • Have the appliance model and part number to hand when checking compatibility against the manufacturer's parts list
