Frequently Asked Questions (FAQ)

• What is the difference between the suffix codes on the 21504-00-72-10-02?
  The suffix defines the physical configuration. "00" means a 0mm tip (flush), "72" is a 7.2-inch case, "10" is a 1.0-meter cable, and "02" specifies the mini coax connector [citation:1][citation:10].
• Is this probe compatible with other metals besides AISI 4140 steel?
  Bently Nevada calibrates these for AISI 4140 steel. Different metals (like aluminum or brass) have different electrical properties and may require recalibration for accurate readings [citation:7].
• What is the maximum temperature the probe tip can withstand?
  The probe tip and cable assembly can tolerate extreme temperatures ranging from -34°C to +177°C, making it suitable for harsh turbine and compressor environments.
