Bently Nevada Vibration Transmitter (P3403893-0351)

Description:

• The P3403893-0351 model is a vibration transmitter used for monitoring vibration levels in machinery.
• It is intended for use with proximity probes and provides a 4 to 20 mA output signal proportional to the measured vibration.
• Commonly used in applications involving centrifugal air compressors, small pumps, motors, or fans.

Electrical Specifications:

• Input:

  • Accepts 1 non-contacting proximity probe and extension cable.

• Power Requirements:

  • Requires +12 to +35 Vdc at the transmitter terminal.

• Signal Output:

  • Provides a 4 to 20 mA dc output over the specified full-scale range.
