Description

The 3500/64M 176449-05 is a four-channel, single-slot monitor for monitoring dynamic pressure in industrial systems. Each channel accepts high-temperature pressure transducer inputs and measures bandpass dynamic pressure, configurable through 3500 Rack Configuration Software. The 3500/64M 176449-05 provides independent +4 to +20 mA recorder outputs per channel, which remain accurate even during short circuits.

It supports 2-wire transducers with 3.3 mA at 22 Vdc and 3-wire transducers with -24 Vdc supply. Input impedance is 10 kΩ for 3-wire and 1.5–3.5 MΩ for 2-wire setups. Dynamic pressure sensitivity is 100 mV/psi (1.45 mV/mBar) with resolution of 0.3662 µA per bit, ±0.25% at room temperature, and -0.66% to +0.70% across operating temperatures. Alert and danger delays are adjustable from 0.1–60 seconds. Voltage compliance ranges 0–12 Vdc across 0–600 Ω load, with update rates near 100 ms.

The 3500/64M 176449-05 ensures machinery protection by triggering alarms based on precise dynamic pressure readings and provides critical real-time data to operators for maintenance and control decisions.
