Two-Channel Protection with the 135305-01
The 135305-01 monitors two independent vibration channels inside Bently Nevada machinery protection racks. This dual monitor processes radial and axial transducer signals on a single board. Reliability engineers therefore apply it to turbines and compressors with limited rack space. Its full-width format fits standard rack slots without extra mounting hardware.
Detailed Technical Parameters
Channel independence defines the 135305-01, because each input path carries its own amplifier and alarm logic. The module filters noise before converting readings into vibration values. Meanwhile, front-panel indicators reveal channel status during walkdown checks. Review the essential specifications in the table below.
| Parameter | Specification |
|---|---|
| Function | Dual-channel vibration monitoring for protection racks |
| Input signals | Two independent proximity probe or seismic inputs |
| Dimensions (W × H × D) | 40 × 220 × 250 mm |
| Weight | Approximately 1.2 kg |
| Interface | Rack backplane connector plus front transducer terminals |
| Component count | Two input amplifier stages plus processing board |
| Energy storage | Local decoupling capacitor array |
| Operating temperature | 0 °C to 65 °C |
Integration into Monitoring Racks
The 135305-01 fits into a standard rack slot and connects through the backplane connector. Commissioning engineers verify probe gaps and alarm setpoints during startup procedures. Consequently, both protection channels return to service quickly after board replacement. The module samples both inputs within a fixed interval. Furthermore, the isolated front end resists interference from nearby power cables and drives.
Why Plants Choose This Monitor
Many power stations still operate Bently Nevada racks for their proven machinery protection. Hence, the 135305-01 serves as a dependable spare for keeping paired channels online. Its standardized board format simplifies stock management across multiple sites. In addition, the dual-channel layout reduces spare-part inventory requirements. This monitor keeps vibration protection accurate and plant operations on schedule.
