FAQ
Frequently Asked Questions (FAQ)
Q1: What does the 3500/72M Recip Rod Position Monitor measure?
A1: It measures rod position, rod drop, and hyper-compressor rod motion parameters such as peak-to-peak amplitude, rod angle, crank angle, gap, and instantaneous piston position.
Q2: How many proximity probes can the 3500/72M accept?
A2: It accepts up to four proximity transducer signals across four channels.
Q3: What is the power consumption of the 3500/72M module?
A3: The power consumption is nominally 7.7 watts.
Q4: What is the typical accuracy of the rod position amplitude measurements?
A4: Accuracy is typically within ±0.33% of full-scale, with a maximum deviation of ±1%.
Q5: What kind of frequency response filters are implemented?
A5: It uses fixed peak-to-peak filters (1–600 Hz), a -3 dB gap filter at 0.09 Hz, and constant Q notch/vector filters for 1X, 2X, and Not 1X components.
