BENTLY 3500/44M 140734-03 - Aeroderivitive Gt Vibration Monitor

BENTLY 3500/44M 140734-03 is a four-channel vibration monitor specially designed for aviation-derived gas turbine applications. The following is its detailed introduction:

Characteristics and Functions

Channel configuration: It features 1 to 4 channels for vibration measurement, enabling simultaneous vibration monitoring of multiple critical parts of the gas turbine.

Signal input: Accept signal input from two independent keyphase devices, allowing each channel pair to use different tracking filters, which can more accurately analyze and monitor vibration signals.

Sensor compatibility: It can be connected to the speed sensor through Bentley Nevada interface modules 86517 and 86497, and also to the Velomitor sensor and accelerometer through the Prox/Velom I/O interface. It can be adapted to various types of sensors to meet different measurement requirements.

Filtering options: Signal integration, 1x frequency vibration tracking or bandpass vibration and other filtering options can be configured through the 3500 rack configuration software, which is helpful for extracting and analyzing vibration signals within a specific frequency range and eliminating interference.

Alarm function: Multiple alarm levels can be configured, providing flexible alarm Settings for abnormal vibration conditions. It can promptly remind operators to take measures to prevent equipment failure from escalating.

Technical parameters

Input impedance: The input impedance of the proximity sensor and accelerometer is greater than 95kΩ.

Sensitivity: Optional 3.94 mV/(mm/s) (100 mV/(in/s)) or 5.71 mV/(mm/s) (145 mV/(in/s)).

Power consumption: The typical value is 7.7 watts.

Humidity: It can operate in an environment with 95% no condensation humidity.

Dimensions: 241.3mm×24.4mm×241.8mm.

Weight: 0.91kg.

Application field

Aerospace: Suitable for aerospace-derived gas turbines, it meets the relevant requirements of aero engine manufacturers such as Rolls-Royce, General Electric and United Technologies, ensuring the safe operation and performance monitoring of aero engines.

In the industrial field: In industries such as petrochemicals, power, and steel, it is used to monitor key rotating mechanical equipment that uses aviation-derived gas turbines, helping to detect potential mechanical problems in advance and avoid production disruptions and high maintenance costs caused by equipment failures.
