Product Details

• Manufacturer: Bently Nevada
• Series: 3500/50
• Model/Part Number: 3500/50-01-00-01, 133388-02, 133442-01
• Model Type: Tachometer Module

Description

The 3500/50M Tachometer Module is a 2-channel module designed to measure shaft rotational speed, rotor acceleration, and rotor direction. It accepts input from proximity probes or magnetic pickups and compares these measurements against user-programmable alarm setpoints. The module generates alarms when the setpoints are violated, ensuring continuous monitoring of critical machine parameters.

Specifications

• Inputs:

  • Signal: Accepts up to 2 transducer signals from proximity probes or magnetic pickups.
  • Input Signal Range: +10.0 V to -24.0 V (signals exceeding this range are limited internally by the module).
  • Input Impedance:
    • Standard: 20 kΩ
    • TMR: 40 kΩ
    • Internal Barrier: 7.15 kΩ
  • Transducers: 1 to 2 proximity transducer signals; restrictions apply to magnetic pickups.

• Speed Input:

  • Supports 1 to 255 events per revolution for rotor acceleration and zero-speed channel types.
  • All other channel types support a range of 0.0039 to 255 events per revolution.
  • Maximum Full Scale: 99,999 rpm, with a maximum input frequency of 20 kHz.
  • Minimum Input Frequency:
    • Proximity transducers: 0.0167 Hz (1 rpm for 1 event per revolution).
    • Passive magnetic pickups: 3.3 Hz.

• Power Consumption: 5.8 Watts, typical.
