Overview：
Bently Nevada 330750-40-05 High Temperature Velomitor System
Bently Nevada 330750-40-05 is a high-temperature vibration velocity sensor for extreme high-temperature industrial environments. This system is mainly used to monitor casing vibrations on high-temperature surfaces. The sensor probe and integrated cable can be directly installed on equipment surfaces with a maximum temperature of +400°C (+752°F). This system compensates for the application limitations of the standard 330500 velocity sensor (maximum operating temperature +121°C).
Note: The previous generation was +300°C, and units with serial numbers prefixed with the letter "G" are the current high-temperature upgraded version.

Function & Features：
- Connector-free integration: The 330750-40-05 sensor probe is permanently cable-connected to the signal conditioning electronic module, eliminating high-frequency failure points caused by connector looseness or oxidation, which are common in traditional vibration sensors.
- Rotor fault monitoring: The 330750-40-05 is used to detect vibration changes caused by faults, with the energy from these faults transmitted to the casing. By measuring the casing vibrations, the machine's health condition can be assessed.
- Cable configuration options: The 330750-40-05 offers standard-length cables for direct selection, and also supports custom cable lengths in 1-foot increments. Some cables have upper and lower length limits.
Questions & Answers
💡 FAQ
Q: What is the 330750-40-05 device? What is its main function?
A: The 330750-40-05 is a high-temperature vibration velocity sensor manufactured by Bently Nevada, part of the Velomitor series. This device is used to measure casing vibrations of rotating machinery operating in extreme high-temperature environments. Its main functions are machine protection and predictive maintenance.
Q: Will the measurement performance of the 330750-40-05 be reduced at high temperatures?
A: No. Bently Nevada states that the measurement performance of this high-temperature model-including amplitude accuracy and frequency response-is comparable to that of standard Velomitor sensors designed for low-temperature environments (such as the 330500 series). High-quality vibration data can be obtained even at elevated temperatures.
Q: What is the warranty?
A: 1 year
Q: What is the return and exchange policy?
A: Returns or exchanges are accepted within 7 days of receiving the goods if there are any quality issues, excluding damage caused by human error or misuse.
Q:What are the available shipping methods?
A: FedEx, DHL, UPS, and others.
