Industry Applications
This 330101-20-35-10-02-00 probe excels in turbomachinery, pumps, compressors, and electric motors where shaft vibration and position monitoring are critical. Its rugged 8 mm design provides a thicker PPS encapsulation, offering superior resistance to physical abuse. In high-temperature environments, the extended range option (not included) can operate up to +218°C for the tip, but this standard version handles -52°C to +177°C, suitable for most industrial settings.
Installation & Setup
Mount the probe with the 3/8-24 UNF thread into a properly tapped hole. Ensure the target surface is clean and the gap is set to approximately -9 Vdc for radial vibration measurements. Use shielded triad cable with tinned wiring, and keep field wiring length under 305 meters to avoid signal rolloff. The ClickLoc connector simplifies cable attachment, providing a secure, quick connection.
Maintenance & Reliability
The probe's stainless steel case and PPS tip resist corrosion and wear. Periodically inspect the cable and connector for damage, and verify the probe gap reading to ensure accurate measurements. Avoid exposing the probe to temperatures below -34°C, as this may damage the pressure seal. With proper care, this probe delivers long-term, dependable service, reducing downtime.
