Description

The Bently 330750-20 is a high-temperature Velomitor system manufactured by Bently Nevada, Inc. for vibration and velocity measurement in extremely high-temperature environments. Here is a detailed description of the product:

I. Product overview
Make and Model: Bently Nevada 330750-20
Type: High temperature Velomitor system
Function: Used to measure vibration of bearing housing, housing or structure, as well as speed measurement in high temperature environment
Second, technical characteristics
High temperature tolerance: The system is uniquely designed to isolate the sensitive elements from the signal processing electronics, permanently connected by rigid cables. This design allows the probe to be installed on surfaces with temperatures up to +400 ° C (+752 ° F), while the signal processing electronics can be installed at lower temperatures.
High reliability: Due to the separate design of the sensitive element and signal processing circuit, the possibility of potential sensor failures (such as joint problems) is eliminated and the reliability of the system is improved.
Widely used: Suitable for electric power, petroleum, chemical, metallurgy and other industries as well as some scientific research units, for large rotating machinery shaft shell online measurement and protection.
