Product introduction
The BENTLY NEVADA 172103 – 01 is a high – performance signal conditioning module designed for industrial machinery monitoring systems. As a critical component in BENTLY NEVADA’s portfolio, it serves as a bridge between raw sensor signals and processing units, ensuring accurate data conversion and transmission.
Integral to machinery protection setups, the BENTLY NEVADA 172103 – 01 excels at conditioning signals from vibration, displacement, and temperature sensors. Its 8 – channel design allows simultaneous processing of multiple inputs, converting them into standardized 4 – 20mA outputs for seamless integration with control systems. This capability makes it indispensable in automation systems where precise, real – time machinery data is essential for operational safety and efficiency.
Core advantages and technical highlights
Superior signal conditioning: The 172103 – 01 delivers exceptional signal processing with ±0.1% full – scale linearity, ensuring minimal distortion of raw sensor data. This precision is vital for detecting subtle changes in machinery behavior, such as early – stage bearing wear or rotor imbalance. Its low noise level (<1mV RMS) further enhances signal integrity, even in electrically noisy industrial environments.
Multi – channel efficiency: With 8 independent channels, the 172103 – 01 allows monitoring of multiple machine points within a single module, reducing rack space requirements and system complexity. Each channel operates independently, preventing cross – talk and ensuring reliable performance across all inputs. This design is particularly valuable in compact industrial enclosures where space is limited.
Robust environmental tolerance: Operating reliably from – 30°C to 70°C, the 172103 – 01 thrives in harsh conditions found in refineries, power plants, and manufacturing facilities. Its ability to withstand temperature fluctuations and moderate humidity ensures consistent performance in environments where many electronic components would degrade, reducing maintenance needs in challenging settings.
Seamless system integration: The 172103 – 01 is fully compatible with BENTLY NEVADA’s 3500 series racks and monitoring systems, enabling plug – and – play installation. Its standardized 4 – 20mA outputs ensure compatibility with most industrial control systems, DCS, and SCADA platforms, simplifying integration into existing automation architectures.
Typical application scenarios
In power generation plants, the 172103 – 01 plays a key role in turbine monitoring systems. It conditions vibration signals from proximity probes mounted on turbine shafts, converting them into stable 4 – 20mA outputs for the 3500 monitoring system. This allows operators to track shaft orbit, radial vibration, and thrust position in real – time, enabling early detection of issues like misalignment or bearing degradation that could lead to costly turbine failures.
Within the petrochemical industry, the 172103 – 01 is widely used in compressor trains. It processes signals from vibration and temperature sensors installed on compressor casings and motor bearings, providing conditioned data to control systems. In offshore platforms, its robust environmental tolerance ensures reliable operation despite salt spray and temperature variations, making it ideal for monitoring critical pumping equipment.
In manufacturing facilities, the 172103 – 01 supports condition monitoring of large motors and fans. By conditioning signals from accelerometers and displacement sensors, it helps maintenance teams track equipment health, schedule preventive maintenance, and avoid unplanned downtime. Its multi – channel design is particularly beneficial in production lines with multiple rotating assets, consolidating monitoring into a compact system.
