Frequently Asked Questions (FAQ)

Q1: What is the primary function of the 3500/77M Recip Cylinder Pressure Monitor?
A1: The monitor continuously evaluates cylinder pressure in reciprocating compressors to provide machinery protection and essential diagnostic data by comparing measured parameters to user-configured alarm setpoints.

Q2: How many channels does the 3500/77M module support?
A2: The module supports up to 4 channels, each capable of processing input from approved pressure transducers.

Q3: Which pressure measurements does each channel provide?
A3: Each channel can output Discharge Pressure, Suction Pressure, Maximum Pressure, Minimum Pressure, and Compression Ratio. Additionally, derived values such as Peak Rod Compression, Peak Rod Tension, and Degree of Rod Reversal are computed.

Q4: What kind of transducers are compatible with this monitor?
A4: Only Bently Nevada approved third-party positive voltage pressure transducers are compatible.

Q5: What is the pressure measurement accuracy of the monitor?
A5: At 25°C, the accuracy is within ±0.5% of the full-range transducer voltage; over a –30°C to +65°C range, it is within ±1.0%.

Q6: Does the monitor provide real-time transducer output access?
A6: Yes, it includes buffered transducer outputs through front-panel coaxial connectors that are short-circuit protected.

Q7: Can this monitor be used in hazardous environments?
A7: Yes, it is certified for use in hazardous areas with approvals such as ATEX, IECEx, cNRTLus, and meets Class I Division 2 and Zone 2 requirements.

Q8: What are the power supply requirements for the transducers?
A8: Each channel supplies +23.0 Vdc ±0.8 Vdc with current limiting at 24.5 mA.
