Bently Nevada 74712-06-05-03-00

Product Features

Bently Nevada 74712-06-05-03-00 adopts a moving coil design, generating an induced voltage through the movement of the coil in a magnetic field, and the output signal is directly proportional to the vibration speed, without the need for an external power supply, making it suitable for portable measurements.

Bently Nevada 74712-06-05-03-00 optimized for high-temperature environments, it has an operating temperature range of -29°C to +204°C (-20°F to +400°F), far exceeding standard models for high-temperature applications such as chemical and power generation.

Anodized aluminum A204, corrosion-resistant and lightweight, silicone rubber (adapted to high-temperature environments to avoid aging), and polyphenylene sulfide (PPS) for the terminal block option with nickel-plated copper contacts provide excellent insulation and temperature resistance.

Bently Nevada 74712-06-05-03-00 has low sensitivity to shock or pulsed excitation, making it suitable for complex industrial environments, high amplitude linearity (±5%) to ensure vibration measurement accuracy, and support for long-distance cabling (up to 305 meters of lead length) to meet the needs of large equipment monitoring.

Product Using Principle

Bently Nevada 74712-06-05-03-00 is mounted on a bearing housing, machine casing or structure by means of a 1/2-20 UNF-3A stud at an angle of 0°±100° to ensure that the sensitive shaft is aligned in the direction of vibration monitoring.

When the machine vibrates, the coil inside it moves with the housing and cuts magnetic lines of inductance in the magnetic field, generating an induced voltage proportional to the speed of vibration.

The voltage signal is transmitted through the connector on the top of the terminal block to the monitoring equipment (e.g. 3300/3500 monitor), where it is processed to display the vibration velocity value, which is used to determine whether the equipment is unbalanced or misaligned.

Product Applications

Bently Nevada 74712-06-05-03-00 is mainly used for equipment vibration monitoring in high temperature industrial environments, typical scenarios include:

Vibration monitoring of bearing seats of rotating machinery such as gas turbines and steam turbines.

Shell vibration measurement of equipment such as chemical reactors and high temperature pumps.

Portable inspection tasks that require periodic or continuous monitoring of vibration status (easy to use on the move as no external power supply is required).

Identification of abnormal case vibration due to rotor faults (e.g., unbalance, misalignment) and early warning of equipment failure.
