X Category: CHT Leads

Alcor Leads

  • High quality stranded material for flexibility and long life
    (cheapy single stranded leads are prone to break)
  • Used to attach a thermocouple probe to a gauge
  • Must be of the same type as the thermocouple
    (e.g. A type J probe must use type J leads)

CHT Leads:

  • Integrated resistor ensures the same resistance regardless of length
  • Choose leads based on the distance from the probe to the gauge

Calibration note:
EGT gauges with relative lean to peak markings may be easily recalibrated in flight per the instructions provided with the gauge. TIT, CHT and EGT gauges with True Temperature markings must either be recalibrated with an Alcal System Tester or returned to Alcor for recalibration if the total lead and probe resistance does not match the gauge calibration.

 

Digital or amplified gauges from other manufacturers are not sensitive to lead resistance, therefore leads may be shortened as needed for these applications without requiring recalibration.
