Overview
The 3500/72M Recip Rod Position Monitor is a four-channel module designed for Bently Nevada 3500 Series racks. It accepts signals from proximity transducers and delivers precise measurements of rod position, rod drop, and hyper compressor motion. Programmable alarms and front panel diagnostics help operators maintain optimal machine performance and protection.
Key Features
- Four-channel input for proximity transducers
- Measures Rod Position, Rod Drop, and Hyper Compressor values
- User-programmable alarms for enhanced monitoring
- Front panel LEDs for status and diagnostics
- Buffered, short-circuit protected transducer outputs
- Fully compatible with 3500 Series Racks
