Bently Nevada 149811-01 Trendmaster Input Card

Description

The Bently Nevada 149811-01 is a high-performance Transducer Direct Input Card designed for the Trendmaster Dynamic Scanning Module (DSM) system. It provides a specialized interface for -24V voltage-mode sensors, enabling the direct acquisition of critical vibration and displacement data for plant-wide machinery condition monitoring.

Specifications

• Part Number: 149811-01

• Input Channels: 4 independent sensor input channels per card.

• Transducer Type: Supports 3-wire voltage mode sensors (e.g., Bently Nevada 3300 series).

• Supply Voltage: Provides -24V DC (± 5%) transducer power.

• Frequency Response: 1/3 Hz to 24 kHz (3 dB corners) for wide-bandwidth monitoring.

• Resolution: 14-bit to 16-bit high-resolution analog-to-digital conversion.

• Input Impedance: 10 kΩ for optimized signal loading.

• Operating Temperature: -20°C to +65°C (-4°F to +149°F).

Features

• Onboard Processing: Performs real-time local calculations for True RMS, peak-to-peak, and 1X/2X vibration variables to reduce network bandwidth.

• Synchronous Sampling: Supports both synchronous and asynchronous processing to accurately capture machinery orbit plots and spectral data.

• Redundancy & Reliability: Features automatic self-checking routines for the card and connected transducers to ensure data integrity.

• Configurable Filtering: Includes user-configurable high-pass, band-pass, and rotor region filters for precise signal analysis.

• Hot-Swappable Design: Can be installed in any of the four general-purpose slots of a Trendmaster DSM rack without interrupting system communications.
