BENTLY NEVADA 3500/50 133388-02 Tachometer Module
Description
The BENTLY NEVADA 3500/50 133388-02 Tachometer Module is a core component of the Bently Nevada 3500 series monitoring system, designed specifically for rotational machinery speed measurement. It features a 2-channel design that simultaneously accepts input signals from proximity sensors or magnetic pickups, with an input voltage range of +10.0 V to -24.0 V and selectable input impedances of 20 kΩ (standard), 40 kΩ (TMR), and 7.15 kΩ (internal barrier). Key functional capabilities include high-precision rotational speed measurement, plus detection of speed change rates and reverse rotation, with configurable output signals including speed, peak speed, reverse rotation count, pulse signals, and Keyphasor signals for integration with other monitoring components. Equipped with multiple alarm functions such as overspeed, underspeed, and reverse rotation alerts, it safeguards reliable, safe operation of rotating equipment. Additional highlights include flexible configuration via 3500 frame configuration software, which supports three monitoring configurations to match diverse application needs, and a modular design for simplified installation and maintenance. Operating temperature ranges from -40 degrees Celsius to 70 degrees Celsius, with a storage temperature range of -40 degrees Celsius to 85 degrees Celsius, and it has a weight of 0.5 kg.
