3500/40M 176449-01

Product introduction

The BENTLY NEVADA 3500/40M 176449-01 is a multi-channel transducer signal conditioner module, engineered to serve as a versatile interface between a wide range of industrial sensors—including the 87199-01 eddy current proximity sensor—and the 3500 series machinery protection system. Designed to handle multiple sensor types simultaneously, this module excels at conditioning, filtering, and converting raw signals into standardized outputs that can be seamlessly integrated with downstream components like relay modules, display units, and analysis software.

As an enhanced variant of the standard 3500/40 series, the 3500/40M 176449-01 offers 8 input and 8 output channels, making it ideal for applications requiring centralized processing of diverse parameters. It is particularly well-suited for working with the 87199-01 sensor, as it is optimized to process the eddy current signals generated by this proximity sensor, ensuring accurate measurement of shaft vibration, position, and speed in rotating machinery. By converting these specialized signals into industry-standard 4-20mA outputs, the module enables easy integration with both 3500 series modules (such as the 3500/60 163179-01 relay module) and external systems like DCS or SCADA, providing a comprehensive solution for machinery health monitoring.

Core advantages and technical highlights

Multi-sensor integration capability: The 3500/40M 176449-01 supports a diverse range of input types, including the eddy current signals from the 87199-01 sensor, ±10V DC signals from pressure transducers, and 4-20mA signals from temperature probes. This versatility allows it to serve as a central hub for conditioning data from multiple sensor types in complex machinery, reducing the need for multiple specialized modules and simplifying system architecture.

Optimized for eddy current sensors: Unlike generic signal conditioners, the 3500/40M 176449-01 is specifically calibrated to process the -2V to +2V output of the 87199-01 eddy current sensor. It includes dedicated signal conditioning circuits that minimize noise and enhance the accuracy of shaft vibration and position measurements, ensuring that the subtle changes detected by the 87199-01 are preserved and accurately transmitted to monitoring systems.

High-resolution processing: Equipped with 18-bit ADC resolution and configurable filtering (0.1Hz to 10kHz), the module delivers precise signal conversion and noise reduction. This level of resolution is critical for capturing the high-frequency components of vibration signals from the 87199-01—such as those caused by bearing defects or rotor imbalance—enabling early detection of machinery issues.

Scalable channel configuration: With 8 input and 8 output channels, the 3500/40M 176449-01 can handle multiple 87199-01 sensors monitoring different points on a single machine (e.g., multiple bearings on a turbine shaft) or a mix of sensors (proximity, temperature, pressure) across various components. This scalability makes it ideal for large-scale installations where centralized signal processing is preferred.

Typical application scenarios

In a steam turbine power plant, the 3500/40M 176449-01 is used to process signals from four 87199-01 sensors monitoring shaft vibration and axial position at different bearing locations. The module conditions these eddy current signals, filters out high-frequency noise from the turbine’s operation, and converts them to 4-20mA outputs. These outputs are sent to the 3500/60 163179-01 relay module, which triggers alarms or shutdowns if vibration exceeds safe thresholds, and to the 170180-01-00 software for trend analysis and diagnostics. The module’s multi-channel design allows it to also process temperature signals from thermocouples, providing a holistic view of turbine health.

Within a chemical plant’s centrifugal pump system, the module integrates signals from 87199-01 sensors (monitoring pump shaft vibration) and pressure transducers (measuring discharge pressure). It conditions both signal types, ensuring that vibration data from the 87199-01 is accurately synchronized with pressure readings. This synchronized data is displayed on the 3500/50 133388-02 module for local monitoring and transmitted to the plant’s DCS via the 3500/93 communication gateway. If a correlation between high vibration and pressure spikes is detected by 170180-01-00 software, maintenance teams are alerted to check for impeller wear.

In a paper mill’s dryer section, the 3500/40M 176449-01 processes signals from 87199-01 sensors installed on multiple dryer rolls, monitoring shaft runout and vibration. The module’s 8 channels allow it to handle sensors from four rolls simultaneously, converting their signals to standardized outputs. These outputs are used by the 3500/60 163179-01 to activate warning lights if runout exceeds tolerance, helping operators prevent paper tearing or roll damage. The 170180-01-00 software uses the module’s data to generate reports on roll condition, enabling scheduled maintenance during production breaks.

Relationship with 87199-01 and other modules

The 3500/40M 176449-01 acts as a critical intermediary between the 87199-01 sensor and the broader 3500 series ecosystem:

With 87199-01: The module is specifically designed to process the eddy current signals from the 87199-01 sensor. It amplifies the sensor’s -2V to +2V output, applies appropriate filtering to remove noise, and converts it to a 4-20mA signal proportional to shaft vibration or position. This conditioned signal is then available for use by other modules and software, ensuring that the 87199-01’s measurements are accurately integrated into the protection system.

With 170180-01-00: The software configures the 3500/40M 176449-01’s filtering parameters, scaling, and alarm thresholds for the 87199-01 sensor. It retrieves conditioned data from the module, enabling real-time monitoring, trend analysis, and spectral analysis of vibration signals. Engineers can use the software to correlate 87199-01 data (via the module) with other parameters, such as temperature, to diagnose machinery faults.

With 3500/60 163179-01: The relay module receives conditioned signals from the 3500/40M 176449-01, including those derived from the 87199-01 sensor. When vibration or position exceeds thresholds, the 3500/40M 176449-01 sends a signal to the 3500/60 163179-01, which activates relays to trigger alarms or shutdowns, ensuring rapid response to critical conditions.

With 3500/05: The rack interface module aggregates data from the 3500/40M 176449-01 (including processed 87199-01 signals) and distributes it to local displays (e.g., 3500/50 133388-02) and remote systems. It also enables configuration of the 3500/40M 176449-01 via the backplane, ensuring seamless integration into the rack.

Installation, calibration and maintenance instructions

Installation preparation: Install the 3500/40M 176449-01 in a 3500 series rack, occupying 2 consecutive slots. Power off the rack and use an anti-static wrist strap during installation. Ensure the module is positioned to facilitate wiring from multiple sensors, including 87199-01 proximity sensors. Required tools include a torque wrench (0.5-0.7Nm), wire strippers, and terminal block screwdrivers.

Wiring and connection: Connect the 87199-01 sensors to the module’s input channels using shielded twisted-pair cable (e.g., 149992-01), ensuring proper grounding at the sensor end to avoid ground loops. Connect other sensors (e.g., temperature probes) to remaining channels as needed. Wire the output channels to downstream devices such as the 3500/60 163179-01 relay module or DCS inputs. Label all connections clearly to avoid confusion.

Calibration: Use 170180-01-00 software to calibrate the 3500/40M 176449-01 for the 87199-01 sensors. For each channel, set the input type to “eddy current sensor” and configure scaling based on the 87199-01’s measurement range (0.25mm to 2.54mm). Use a calibration fixture to apply known gap values and adjust the module’s output to match, ensuring accuracy within ±1% of full scale. Repeat for other sensor types connected to the module.

Maintenance suggestions: Perform monthly visual inspections to check for loose connections, corrosion on terminal blocks, or damage to sensor cables. Clean terminals with a dry cloth and tighten connections as needed. Quarterly, verify the module’s filtering and signal conditioning by comparing its output to a reference signal generator. Re-calibrate annually using 170180-01-00 software to account for drift, especially for channels connected to 87199-01 sensors, where precision is critical. If channel isolation or signal accuracy degrades, contact technical support for repair or replacement.
