FAQ
Frequently Asked Questions (FAQs)
Q1: What is the main purpose of the 3500/77M Cylinder Pressure I/O Module?
A1: It interfaces with pressure transducers to condition and transmit pressure signals to the monitor for real-time protection and performance evaluation of reciprocating compressors.
Q2: How many channels does the 143737-01 module support?
A2: The module supports up to four independent pressure input channels.
Q3: What type of transducers are compatible with this module?
A3: Only Bently Nevada approved third-party positive voltage pressure transducers (psia) are compatible.
Q4: Is this module suitable for both internal and external termination?
A4: No. The 143737-01 model specifically supports external termination only.
Q5: What is the buffered output used for?
A5: Buffered transducer outputs provide raw signal access for analysis or diagnostic use without interfering with monitoring.
Q6: What mechanical variables can the module calculate?
A6: Peak Rod Compression, Peak Rod Tension, and Degree of Rod Reversal.
Q7: What is the environmental operating temperature range?
A7: It operates between -30°C and +65°C (-22°F to +150°F).
Q8: What are the dimensions and weight of the I/O module?
A8: The module measures 241.3 × 24.4 × 99.1 mm and weighs 0.20 kg.
