3500/77M 176449-07 BENTLY cylinder pressure monitor

Thank you for providing detailed information about the Bently Nevada 3500/77M Recip Cylinder Pressure Monitor. Here’s a summary:

Overview:

• Type: 4-channel monitor
• Input: Accepts input from Bently Nevada approved pressure transducers
• Functionality: Conditions the signal for various pressure measurements for reciprocating compressors
• Purpose:
  • Provides machinery protection by comparing monitored parameters against configured alarm setpoints.
  • Offers essential machine information for operations and maintenance personnel.

Measured Variables (Each Channel):

• Discharge Pressure
• Suction Pressure
• Maximum Pressure
• Minimum Pressure
• Compression Ratio

Configuration Options:

• Users can configure Alert setpoints for each active measured variable.
• Danger setpoints can be configured for any two of the active measured variables.

Ordering Considerations:

• Firmware and Software Revisions Required:
  • 3500/77M Module Firmware Revision L
  • 3500/01 Software – Version 3.00
  • 3500/02 Software – Version 2.30
  • 3500/03 Software – Version 1.30
• External Termination Blocks cannot be used with Internal Termination I/O Modules.
• For I/O Modules with External Terminations, External Termination Blocks and Cables must be ordered separately.
• The standard product has a lower limit for machine speed at 60 RPM. For machine speeds down to 30 RPM, modification 135M8200-01 is required.

Specifications:

• Inputs:
  • Signal: Accepts 1 to 4 channels of Bently Nevada approved positive voltage 3rd-party pressure transducers (psia).
• Scale Factor Range:
  • 95,000 mV/psi for 100 psia
  • 38,000 mV/psi for 250 psia
  • 19,000 mV/psi for 500 psia
  • 9,500 mV/psi for 1000 psia
  • 3,800 mV/psi for 2500 psia
  • 1,900 mV/psi for 5000 psia
  • 950 mV/psi for 10,000 psia
