BENTLY 3500/40M P/N：176449-01
Full name: Proximitor Monitor Four Channel Proximitor Monitoring Module (4-channel Displacement/Vibration Monitor)
Belonging to Baker Hughes Bently Nevada 3500 Unit Protection System

3500/40M physical front

Real time shooting of module panel
1、 Basic Overview
3500/40M is the core universal monitoring card of the 3500 system, which receives signals from eddy current sensors (3300XL series); Channel pairing configuration (1&2 channels grouped together, 3&4 channels grouped together), two groups can be configured with different monitoring functions.
Commonly known as the universal card for shaft vibration/shaft displacement/differential expansion, it is commonly referred to as a four channel displacement monitor in the market.
Configurable monitoring function
Radial vibration (shaft vibration)
Thrust position (axial displacement)
Eccentricity
Differential expansion
REBAM relative bearing rotor motion monitoring
2、 Core hardware specifications
Channel: 4-channel independent eddy current sensor input, 4-channel BNC signal interface on the panel
Sensor compatibility: 3300XL 5mm/8mm/11mm eddy current probe+preamplifier
Alarm mechanism
Each channel supports two levels of programmable alarms: Alert warning and Danger danger;
It can be used in conjunction with 3500/32 and 3500/33 relay modules to achieve interlocking protection.
Panel indicator lights: OK, TX/RX communication, Bypass status
Signal output: Each channel has a buffered sensor output, which can be connected to an external oscilloscope/acquisition instrument
Power consumption: typical 7W, backplane power supply
Installation: Standard 3500/05 rack single slot, supports hot swapping
Compliance: Meets API 670 and supports SIL2 security application scenarios
3、 Key points of model differentiation (easily confused in procurement)
3500/40M 176449-01: Standard 4-channel eddy current monitoring card (this model)
3500/40M 140734-01: High density TMR triple redundancy version, hardware is not universal and cannot be directly interchanged
⚠️ The last digit of the order number represents the hardware firmware version and cannot be replaced arbitrarily. It is necessary to verify that the part number is complete and consistent.
4、 Lifecycle information
Original factory normal supply model; The source of goods includes brand new original stock and disassembled testing spare parts.
Warranty reference: 12 months for brand new original equipment, 3-6 months for disassembled spare parts.
5、 Typical application scenarios
TSI protection system for power plant steam turbines, gas turbines, centrifugal compressors, and air separation units;
Used to monitor key rotor parameters such as shaft vibration, axial displacement, and rotor differential expansion.
