Product Details:

Description:

The 3500/77M Recip Cylinder Pressure Monitor is a 4-channel monitor that accepts input from Bently Nevada approved pressure transducers, conditions the signal to make various bpressure measurements for reciprocating compressors, and compares the conditioned signals with user-programmable alarms.

The primary purpose of the 3500/77M monitor is to provide:

• Machinery protection by continuously comparing monitored parameters against configured alarm setpoints to drive alarms.
• Essential machine information for operations and maintenance personnel.

Depending on configuration, each channel typically conditions its input signal to provide various parameters called measured variables. Users can configure Alert setpoints for each active measured variable and Danger setpoints for any two of the active measured variables.

Each channel of the 3500/77M will provide eight measured variable values that relate to cylinder pressure operation. The five values that relate to a single chamber are as follows:

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

The 3500/77M Module requires the following (or later) firmware and software revisions:

• 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. When ordering I/O Modules with External Terminations, the External Termination Blocks and Cables must be ordered separately.

The lower limit for machine speed is 60 RPM in the standard product. For machine speeds down to 30 RPM, modification 135M8200-01 is required.
