3500/42M Proximitor Seismic Monitor

The 3500/42M Proximitor Seismic Monitor continuously protects machinery by comparing monitored parameters with programmed alarm setpoints. It plays a critical role in informing both operations and maintenance personnel about the machine’s health.

Key Features:

• Monitoring: The monitor accepts input from proximity and seismic transducers, conditioning the signals to provide vibration and position measurements.
• Alarm Functionality: Compares conditioned signals with user-programmable alarms.
• Programmable Channels: It features four channels that can be programmed in pairs for monitoring and reporting up to two functions simultaneously (e.g., radial vibration, acceleration, eccentricity).

Monitored Parameters:

• Radial vibration
• REBAM
• Thrust position
• Acceleration
• Differential expansion
• Shaft absolute
• Eccentricity
• Circular acceptance region
• Velocity

Signal Conditioning:

Each channel processes its input signal to generate static values, which can then be used to configure alert and danger setpoints. Two of these values can be monitored simultaneously, depending on the configuration.

Specifications:
