BENTLY NEVADA 3300/46-46-04-02-01 Differential Expansion Monitor

Product Description：

The Bently Nevada 3300/46-46-04-02-01 Differential Expansion Monitor is a high-performance monitoring system designed for large machines, particularly those that require differential expansion measurements. In large machinery, the challenge of mounting large proximity probes for monitoring can be an obstacle, especially when space is limited or when the machine dimensions exceed the measurement range of standard probes. The 3300/46 Differential Expansion Monitor addresses this issue by utilizing an alternative measurement technique that extends the range of standard transducers, making it an ideal choice for a variety of industrial applications.This monitor features a dual proximity probe setup, where two probes are used to measure ramp surfaces on the rotor. This approach not only increases the monitoring range but also allows for greater flexibility in probe placement. By using ramp surface targets, this monitor can achieve higher accuracy even with smaller transducers. It is particularly beneficial in applications where traditional collar methods are not feasible due to space or mechanical constraints.

Frequently Asked Questions:

1. What is the primary function of the Bently Nevada 3300/46Differential Expansion Monitor?
The 3300/46 Differential Expansion Monitor is designed to measure the differential expansion between two points on rotating machinery, such as turbines or motors. It uses two proximity probes to monitor ramp surfaces on the rotor, providing a high-accuracy measurement of machine displacement. This is critical for ensuring the proper functioning and preventing damage to large industrial machinery.

2. What makes the 3300/46 monitor different from other differential expansion monitors?
The 3300/46 is unique because it uses ramp surfaces on the rotor for measurement. This allows it to offer increased monitoring range with standard transducers and enables greater flexibility in probe placement, which is especially useful in large machines where conventional collar mounting methods are not feasible.

3. Can the 3300/46 be used with other proximity probes?
While the 3300/46 is designed to work with Bently Nevada 3300-series proximity probes, it is essential to verify the compatibility of other probes with the unit's specifications before installation. It is recommended to consult with Bently Nevada for guidance on compatibility if using non-standard probes.
