Quick Detail

Description

The Bently Nevada 3500/72M 176449-08 Recip Rod Position Monitor processes four proximity probe inputs to provide dynamic and static rod position measurements. Each input has 10 kΩ impedance, and the monitor conditions signals with ±0.33% full-scale typical accuracy for position magnitude, gap, 1X and 2X amplitude, and ±1° typical accuracy for rod and crank angles. The 3500/72M 176449-08 calculates rod position, rod drop, and hyper-compressor parameters with nominal scale factors from 0.79 mV/µm to 7.87 mV/µm depending on configuration. Operating from -30°C to +65°C, storing at -40°C to +85°C, and consuming only 7.7 W, the 3500/72M 176449-08 occupies 1 full-height front slot for the main module and 1 rear slot for I/O modules. Front panel LEDs indicate OK, TX/RX communication, and Bypass Mode, enabling operators to track rod positions and trigger alarms using the 3500 Rack Configuration Software for real-time reciprocating compressor protection.

Applications

Measure Rod Position in Reciprocating Compressors
The 3500/72M 176449-08 accepts four proximity probe signals with 10 kΩ input impedance and nominal scale factors from 0.79 mV/µm to 7.87 mV/µm. It provides accurate rod position readings to ±0.33% full-scale typical and rod angle measurements to ±1°, enabling operators to track compressor rod travel in real time.

Monitor Rod Drop During Operation
Using the 3500/72M 176449-08, operators can monitor rod drop with ±0.33% full-scale typical accuracy. The monitor calculates dynamic and static rod drop parameters and provides alerts when thresholds are exceeded, supporting continuous reciprocating compressor operation.

Measure Hyper-Compressor Parameters
The 3500/72M 176449-08 processes signals from four proximity probes and outputs hyper-compressor rod displacement with scale factors of 3.94 mV/µm to 7.87 mV/µm. Frequency response is 1 Hz to 600 Hz, allowing precise measurement of high-speed reciprocating components.

Track Compressor Data with Front Panel LEDs
Front panel OK, TX/RX, and Bypass LEDs on the 3500/72M 176449-08 allow operators to immediately confirm active measurements and communication status, reducing manual verification during automated monitoring.

Specifications

Competitive Advantage

High Precision Signal Conditioning
The 3500/72M 176449-08 provides signal conditioning accuracy within ±0.33% for position magnitude, gap, 1X and 2X amplitude, and ±1° for rod and crank angles. This ensures precise measurements of reciprocating compressor rod position for automated control systems.

Four-Channel Real-Time Monitoring
With four channels, the 3500/72M 176449-08 can simultaneously process multiple proximity probes. It continuously compares measured values to user-programmed alarm setpoints, enabling real-time protection of reciprocating compressor machinery.

Low Power Consumption and Rack Integration
The 3500/72M 176449-08 operates at 7.7 W nominal power, occupies 1 full-height front slot for the main module and 1 rear slot for I/O modules, allowing straightforward installation in existing 3500 rack systems.

Quantitative Monitoring for Automated Safety
The 3500/72M 176449-08 measures rod position, rod drop, and hyper-compressor parameters with scale factors of 0.79 mV/µm to 7.87 mV/µm, providing automated monitoring that triggers alarms and relays when measured values exceed configured thresholds.
