⭐SPECIFICATIONS

Part No.: 3300/16
Manufacturer: Bently Nevada
Product Type: Dual Vibration Monitor
Series: 3300
Availability: In Stock
Country of Origin: United States (USA)

3300/16 is a Dual Vibration Monitor developed by Bently Nevada. It continually detects and monitors two independent channels of radial vibration and average shaft position (gap), with input from two proximity probe/Proximity systems. This monitor is intended to replace the 3300/15 Dual Radial Vibration Monitor, which lacks radial position gap alarms.

⭐3300/16 FIELD WIRING DIAGRAM

• Power Supply user-programmable for -24 Vdc or -18 Vdc, current limited on individual monitor circuit board.
• User-programmable frequency response of 4 to 4,000 Hz (240 to 240,000 cpm) or 1 to 600 Hz (60 to 36,000 cpm); – 3dB
• The 1 to 600 Hz (60 to 36,000 CPM) frequency range is not suggested for machine applications that require rapid startup and coast down rates and acceleration/deceleration rates of more than 1000 rpm/s.
• The monitor circuitry will preserve vibration transients commonly observed during quick startup because of the enlarged low-frequency range to 60 CPM (such as with motor-driven equipment).
• This can keep vibration levels higher than alarm setpoints after alarm time delays.
• Even if the real vibration has reduced below the Danger alarm setpoint level, this may result in Danger relay actuation after the internal time delay has passed.
• If the conventional 4 Hz (240 CPM) low-frequency limit is insufficient for your application, please contact your sales representative.
• For applications where the shaft rotative speed is less than 1,000 rpm, the 1 Hz (60 CPM) option is advised.

⭐3300/16 Recorder Outputs

User-programmable between +4 and +20 mA, 0 and -10 Vdc, or +1 and +5 Vdc. The voltage or current outputs are proportional to the full scale of the programmed monitor. For each channel, separate recorder outputs are provided. Short circuits on recorder outputs have no effect on monitor operation.

• The impedance of output (voltage outputs): 100 The lowest load resistance is 10 k.
• Voltage Compliance (current outputs): 0 to +12 Vdc across the load range. When using the +4 to +20 mA option, the load resistance is 0 to 600.
• Accuracy of the recorder (in addition to signal conditioning accuracy) at +25°C (+77°F):
  • +4 to +20 mA: 0.7% of signal, 0.09 mA offset
  • +1 to +5 Vdc: 1.1 percent of signal with a 10 mV offset.
  • 0 to -10 Vdc: 1.1% of signal, 15 mV offset

⭐Relays

Each monitor can have one alarm relay module installed behind it. Each 3300 System must include at least one relay module.

Displays

Liquid Crystal Display with non-multiplexing vertical bar graph (LCD). Each channel has its own 63-segment LCD. On a third, center scale, the probe gap is indicated. LCD is also used.

Frequency Response

• – 3dB nominal; user-programmable for 4 to 4,000 Hz (240 to 240,000 cpm) or 1 to 600 Hz (60 to 36,000 cpm).

The 1 to 600 Hz (60 to 36,000 cpm) frequency range is not recommended for machine applications that require rapid startup and coast down rates and acceleration/deceleration rates greater than 1000 rpm/s. The monitor circuitry will retain vibration transients normally experienced during fast startup because of the extended low-frequency range to 60 cpm (such as with motor driven equipment). This can keep vibration levels higher than alarm setpoints after alarm time delays. Even if the actual vibration has decreased below the Danger alarm setpoint level, this may result in Danger relay actuation after the internal time delay has passed. If the standard 4 Hz (240 cpm) low-frequency limit is insufficient for your application, please contact your sales representative. For applications where the shaft rotative speed is less than 1,000 rpm, the 1 Hz (60 cpm) option is recommended.
