8. FAQ (10 Questions & Answers, QA Format)

Q1: How many pressure transducers can be connected to the 3500/64M 176449‑05?
A: It supports between 1 and 4 pressure transducer inputs depending on what your system requires; unused channels can be left inactive.

Q2: What types of pressure transducers are compatible (2‑wire vs 3‑wire)?
A: Both types are compatible. For 3‑wire transducers the input impedance is about 10 kΩ, and for 2‑wire transducers it is in the range of 1.5 MΩ to 3.5 MΩ typically.

Q3: What is the frequency response range of this monitor?
A: It offers a Low mode of roughly 5 Hz to 4 kHz, and a High mode of about 10 Hz to 14.75 kHz, depending on configuration and transducer.

Q4: What is the typical sensitivity or dynamic pressure scale?
A: Sensitivity is approximately 100 mV per psi (which corresponds to ~1.45 mV per mBar) for dynamic pressure.

Q5: What are the size and weight of this module?
A: The physical dimensions are about 2.6 cm × 25.8 cm × 24 cm, and the module weighs approximately 0.8 kg.

Q6: What are the operating temperature and storage temperature ranges?
A: Operating temperature: about ‑55°C to +85°C; storage: roughly ‑40°C to +85°C.

Q7: What output options does it provide?
A: It provides recorder outputs (typically +4‑20 mA per channel) proportional to full‑scale, plus buffered outputs. Also status LEDs (OK, TX/RX, Bypass) for diagnostics.

Q8: How is alarm triggering handled?
A: The module compares measured dynamic pressure (band‑pass filtered) against configured alarm setpoints; when exceeded, it drives alarms. Delay / threshold configuration is usually possible.

Q9: What is the power requirement?
A: Nominal supply is 24 VDC, with maximum power draw given as ~12 W under full load.

Q10: In which industries is this monitor especially useful?
A: Common applications are in power generation, oil & gas, compressor and turbine monitoring, pumps, and chemical processing where fast pressure transients or surges indicate mechanical stress or failure potential.
