Product introduction
The BENTLY NEVADA 135799-01 is a compact, high-performance signal conditioning amplifier designed to enhance and process signals from eddy current sensors such as the 87199-01, before they are fed into larger systems like the 3500/40M 176449-01 multi-channel transducer signal conditioner module. This specialized amplifier plays a crucial role in industrial machinery monitoring by refining raw sensor signals, reducing noise, and ensuring optimal signal quality for downstream processing.
As a dedicated signal conditioning solution, the 135799-01 is engineered to work seamlessly with eddy current sensors, which are widely used to measure shaft vibration, position, and speed in rotating machinery. By amplifying the weak -2V to +2V output of sensors like the 87199-01 and providing configurable gain options, this amplifier ensures that even the smallest signal variations are preserved and accurately transmitted. Its compact design and DIN rail mountable feature make it easy to integrate into existing setups, whether as a standalone unit or as part of a larger 3500 series system.
The 135799-01 acts as a vital intermediary between sensors and more complex conditioning modules like the 3500/40M 176449-01, enhancing the overall accuracy and reliability of the monitoring system. It is particularly valuable in environments where sensor signals may be degraded by long cable runs or electromagnetic interference, ensuring that the data reaching the 3500/40M 176449-01 and subsequent analysis software like 170180-01-00 is of the highest quality.
Core advantages and technical highlights
Signal amplification and noise reduction: The 135799-01 features advanced filtering and amplification circuitry that enhances the weak signals from 87199-01 eddy current sensors. With configurable gain ranging from 1x to 10x, it can amplify subtle signal variations caused by small shaft movements or vibrations, ensuring these details are not lost during transmission to the 3500/40M 176449-01 module. Its built-in noise reduction filters further improve signal quality by minimizing electromagnetic interference (EMI) and radio frequency interference (RFI) commonly found in industrial environments.
Seamless integration with eddy current sensors: Specifically calibrated to work with eddy current sensors like the 87199-01, the 135799-01 is optimized to handle their unique signal characteristics. It maintains the sensor’s frequency response up to 10 kHz, ensuring that high-frequency vibration components—critical for detecting early-stage bearing defects or rotor imbalance—are accurately preserved. This tailored compatibility eliminates signal distortion that can occur with generic amplifiers, providing more reliable data for the 3500/40M 176449-01 to process.
Compact and flexible installation: With its small form factor (12.2mm width) and DIN rail mountable design, the 135799-01 is ideal for installations where space is limited, such as control cabinets or machinery enclosures. It can be easily positioned close to the 87199-01 sensor to minimize cable length and reduce signal degradation, while still connecting seamlessly to the 3500/40M 176449-01 module via standard wiring. This flexibility makes it suitable for both new installations and retrofits of existing monitoring systems.
Enhanced system accuracy: By conditioning signals before they reach the 3500/40M 176449-01, the 135799-01 improves the overall accuracy of the monitoring system. It ensures that the 3500/40M 176449-01 receives a clean, amplified signal, reducing the risk of measurement errors and false alarms. This is particularly important for critical applications like turbine or compressor monitoring, where accurate vibration and position data is essential for preventing machinery failure.
Typical application scenarios
In a gas turbine power plant, 135799-01 amplifiers are installed near 87199-01 sensors monitoring turbine shaft vibration. The amplifiers condition the sensor signals, reducing noise from the turbine’s high-voltage environment, and transmit the enhanced signals to the 3500/40M 176449-01 module. The 3500/40M 176449-01 then processes these signals and sends them to the 3500/60 163179-01 relay module, which triggers alarms if vibration levels exceed safe thresholds. Engineers using 170180-01-00 software benefit from the improved signal quality, enabling more accurate analysis of vibration trends and early detection of potential issues.
Within a paper mill’s dryer section, 135799-01 amplifiers are used to condition signals from 87199-01 sensors monitoring dryer roll vibration. The amplifiers’ compact size allows them to be mounted directly on the machinery, minimizing cable length and signal loss. The conditioned signals are sent to the 3500/40M 176449-01 module, which integrates them with temperature and pressure data to provide a comprehensive view of roll health. Operators using the 3500/50 133388-02 display module can easily monitor vibration levels, while the 170180-01-00 software uses the high-quality data to generate maintenance reports.
In an oil refinery’s centrifugal pump system, 135799-01 amplifiers are deployed to enhance signals from 87199-01 sensors measuring pump shaft position and vibration. The amplifiers’ noise reduction capabilities are critical in this environment, where electrical interference from nearby motors can degrade sensor signals. The conditioned signals are transmitted to the 3500/40M 176449-01 module, which converts them to standardized outputs for the refinery’s DCS. This ensures that the DCS receives accurate data, enabling precise control of pump operations and timely response to any deviations from normal operating conditions.
