Where PR9268/202-100 Fits
The PR9268 family is intended for absolute vibration measurement on machine cases. Typical machinery applications include steam turbines, gas turbines, hydro turbines, compressors, pumps and fans. The sensor is designed to form part of a machinery protection or monitoring chain. Replacement / Fault Considerations
When replacing a PR9268 sensor, the measurement orientation, cable length, cable protection and connector configuration should be matched before ordering. For PR9268/202-100, particular attention should be given to its vertical mounting configuration, 8 m armored cable and Harting plug. |

|
Can PR9268/202-100 replace another PR9268 sensor directly?
Not automatically. The PR9268 family includes vertical, horizontal, omni-directional and high-temperature variants with different cable and connector configurations. A replacement should match the required measurement orientation, cable arrangement and connection configuration. PR9268/202-100 is the vertical 8 m armored-cable version with Harting plug.
|
|
Why is the 8 m cable configuration important when ordering PR9268/202-100?
The PR9268 ordering structure distinguishes cable lengths and armored or non-armored versions. PR9268/202-100 specifies the 8 m armored configuration, so changing the cable length or protection can result in a different ordering configuration and may not match an existing installation.
|
|
Does PR9268/202-100 require an external power supply?
The PR9268 is an electrodynamic, self-powered velocity sensor. Its mechanical measuring principle generates the velocity signal without a separate sensor excitation supply. The complete measurement chain still needs to be compatible with the connected monitoring or protection equipment.
|
|
What should be checked before purchasing PR9268/202-100 for a machinery protection system?
Confirm the required vertical measurement orientation, the 28.5 mV/(mm/s) sensitivity class, 4–1000 Hz operating frequency range, 8 m armored cable and Harting plug. The connected monitoring chain should also be checked for electrical and mechanical compatibility.
|
|
When should PR9268/202-100 be considered instead of a PR9268 high-temperature variant?
PR9268/202-100 belongs to the standard-temperature PR9268/20x family, rated for -20 to +100°C. The PR9268/60x and /70x families are high-temperature variants rated for higher operating temperatures. Selection should therefore follow the actual sensor mounting position and environmental temperature requirements.
