Weight:about 0.34 kg(some say about 3.5 kg).

Operating temperature:

-30°C to+65°C(some say-40°C to 85°C),depending on the use of the internal safety barrier I/O module or the key phase I/O module.

Input and output:

Input signal:analog signal from a proximity probe or magnetic pickup,input signal range+0.8 V to-21.0 V(non-isolated input/output module)or+5V to-11V(isolated input/input module),input impedance minimum 21.8 kΩ.

Output signal:Digital keyphaser signal,used to indicate when a specific mark on the rotating shaft is aligned with the keyphaser sensor,output range 1 to 99999 cpm(0.017 to 1667 Hz),output impedance maximum buffered output impedance 504Ω.

Number of channels:

This module is a dual-channel module that can monitor two different signal sources at the same time.In normal configuration,the 3500 mechanical protection system can accept four keyphaser signals;in paired configuration,it can accept eight keyphaser signals.

Response time:

Less than 1 millisecond.

Compatibility:

This module is compatible with other modules in the 3500 series and can be seamlessly integrated into existing systems.At the same time,it also supports field-upgradeable firmware and asset management data reporting.

 

III.Application and Function

The BENTLY 3500/25 149369-01 module is mainly used to provide keyphase signals for the monitor module in the 3500 frame.By receiving input signals from eddy current sensors or electromagnetic sensors and converting them into digital key phase signals,the module can accurately indicate when the key phase mark on the shaft passes the key phase probe.This is essential for measuring machine speed,monitoring machine axial vibration,and predicting the operating status of equipment.

In addition,the module is also widely used in industrial fields such as oil and gas,power,petrochemical,papermaking,and steel for monitoring and protecting key rotating equipment such as generators,turbines,pumps,and compressors.By monitoring vibration and other parameters in real time,timely detecting equipment abnormalities and taking corresponding maintenance measures,it helps to improve equipment reliability and efficiency,reduce downtime,and prevent accidents caused by mechanical failures.

 

The company mainly imports PLC modules,programmable controllers,servo control systems and DCS spare parts,such as:ABB,AB(Rockwell),GE(General Electric),Bentley,Honeywell Er),Emerson.),Motorola,Invensys,Westinghouse,etc.The company has established close cooperative relations with many world-renowned PLC and DCS product maintenance service providers.We can purchase goods directly from abroad and provide equipment and spare parts from different countries and manufacturers.
