Features:
- Multi-Mode Reciprocating Measurement
- Flexible Channel Pairing
- High-Precision Alarm Logic
The 3500/72M 149734-08 directly supports three critical measurement modes for reciprocating machinery: Rod Position, Rod Drop, and Hyper-Compressor, all within a single monitor.
Channels are programmed in pairs (1&2 and 3&4), allowing the monitor to perform two different functions (e.g., Rod Position on pair one and Rod Drop on pair two) simultaneously, maximizing module utility.
Alarm setpoints are adjustable from 0 to 100% of full-scale with an exceptional accuracy of within 0.13% of the desired value, ensuring reliable and repeatable protection thresholds.
The 3500/72M 149734-08 Bently Nevada four-channel, API 618-compliant monitor may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Reciprocating Compressors: Primary application is monitoring rod position and rod drop in gas and air reciprocating compressors per API 618.
- Hyper-Compressor Service: Dedicated measurement mode for ultra-high pressure ethylene and other hyper-compressor applications.
- Machinery Protection Systems: As part of a 3500 series rack, it provides continuous protection and alarm/ trip functionality for critical assets.
- Condition Monitoring: Used to track rider band wear and piston rod health over time through trended static position measurements.
- Temperature Range: Operating temperature of -30°C to +65°C when used with Internal/External Termination I/O modules; 0°C to +65°C with Internal Barrier I/O.
- Storage Limits: Safe storage from -40°C to +85°C.
- Humidity Tolerance: Rated for 95% non-condensing humidity.
- Rack Mounting: Standard 3500 rack mounting; occupies 1 full-height front slot and requires a separate rear I/O module slot.
- High Measurement Accuracy: Provides typical measurement accuracy of within ±0.33% of full-scale for position magnitude, gap, and peak-peak amplitude.
- Low Power Draw: Consumes only 7.7 watts (nominal) , placing minimal load on the 3500 rack power supply.
- Rapid Trip Response: Danger alarms can be set for a nominal delay of just 0.1 seconds, enabling fast machine protection.
- Signal Fidelity: Front-panel buffered transducer outputs (coaxial connectors) provide direct access to raw probe signals for portable data collectors or diagnostic tools.
