Overview:

Bently Nevada 330750-20-05 High Temperature Velomitor mainly serves the field of machinery protection and is used to monitor the casing vibration of industrial machinery. The sensor head and cable of this Velomitor can be directly installed on components with surface temperatures up to +400 °C, enabling vibration data to be acquired close to the heat source. The electronic components of the sensor can be extended via cable to operate in areas with lower temperatures.
Note: For environments with temperatures not exceeding +121 °C, the standard 330500 series piezoelectric velocity sensors are recommended.

Function & Features:

- The 330750-20-05 sensor head can be directly installed on high-temperature surfaces up to +400°C, overcoming the previous limitation of 300°C in earlier versions.
- The 330750-20-05 sensor head is responsible for picking up vibrations at high temperatures, while the electronic unit containing precision circuits can be placed in cooler locations, away from the heat source, with temperatures ranging from -67°F to +250°F.
- The 330750-20-05 sensor measures vibrations transmitted from the rotor to the bearing housing or casing, providing effective protection for the machine.
Questions & Answers
💡 FAQ
Q: Can the 330750-20-05 directly measure the vibration of the rotor?
A: No. The 330750-20-05 measures the vibrations transmitted from the rotor to the bearing housing or casing. To directly measure the vibration of the rotor, a non-contact probe such as an eddy current sensor is required.
Q: How to identify if the 330750-20-05 can be used in a 400°C environment?
A: You can check the serial number. Serial numbers starting with the letter "G" indicate that the sensor can be used in extremely high-temperature environments.
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.
