· Weight: Approximately 1.4 pounds or 0.7kg.

· Sensor type: capable of receiving signals from speed and acceleration sensors.

· Input signal: 20 to 100kHz.

· Output signal: 4 to 20mA.

· Alarm threshold: User configurable.

· Communication interface: Supports Modbus RTU protocol.

· Monitoring of reciprocating compressors: As part of the reciprocating compressor solution, it is used to monitor the vibration of the compressor crankcase and crosshead. 

By monitoring and analyzing the vibration signals, potential faults of the compressor can be detected in a timely manner, such as piston wear, loose connecting rods, and 

valve failures, ensuring the safe and stable operation of the compressor.

· Other reciprocating machinery monitoring: In addition to compressors, it can also be used for monitoring other reciprocating machinery, such as reciprocating pumps, 

reciprocating engines, etc., to help users understand the real-time operation status of equipment, improve equipment reliability and availability, reduce equipment 

maintenance costs and downtime.

· Fault diagnosis and predictive maintenance: This monitor can measure variables such as pulse acceleration, acceleration 2, reciprocating speed, and low-frequency 

reciprocating speed of reciprocating machinery. It analyzes and processes the measurement data, extracts the operating characteristics and fault information of the 

equipment, and provides a basis for fault diagnosis and predictive maintenance of the equipment. Users can develop maintenance plans in advance based on monitoring 

data, carry out timely repairs and maintenance, and avoid equipment failures.

· System integration and automation control: It has multiple communication interfaces and can be integrated with other devices and systems, such as PLC, DCS systems, etc., 

to achieve automation control and monitoring. The monitoring data is transmitted to the central control system for centralized display, analysis, and processing, making it 

convenient for operators to monitor and manage the entire production process, improving production efficiency and quality.
