Issues with Bentley 3500 signal transmission?
Thread Content
What signals are generated by on-site monitoring probes for compressor vibration, displacement, speed, and key phase—amplifiers, Bentley 3500, DCS, or rotary detection systems? For example: 0-5V voltage, 4-20mA signal. Question: 1. Signal from the probe to the amplifier? 2 From the amplifier to the 3500 signal. 3 What is the signal at point DO that results from the output of the 3500? 4 Vibration, displacement, speed, and phase signal from 3500 to DCS? 5 What signals are used in the rotation monitoring systems from 3500 to DS8000? What is the principle behind the DS8000?
The original poster can understand it by going directly to the 3500 framework. All signals entering 3500 are voltage signals; the relay cards output alarm interlock signals in the form of digital signals, while the other IO cards output signals at 4-20mA

If it is an eddy current probe, then it is impedance signal 2 that goes from the amplifier to 3500; generally, it is a voltage signal 3 that comes out of 3500 and serves as the DO signal for triggering an shutdown? There are two ways: one is for the 3500 to send a DO signal to the ITCC, which then sends another DO signal to trigger the shutdown. Another approach is for vibration, displacement, and other signals at 3500 to be fed into the ITCC, which then sends a DO signal to trigger the shutdown of the machine. 4 Vibration, displacement, speed, and phase signal from 3500 to DCS? It is not difficult to generate 4-20mA signals from an AO card with a value of 3500 in order to display vibration, displacement, rotation speed, and phase signals on the DCS; communication can also be used for this purpose. 5 What signals are used in the rotation monitoring systems from 3500 to DS8000? What is the principle behind the DS8000? I don’t know what DS8000 is; it’s something like ITCC, I guess?
1 Signal from probe to amplifier? It is an impedance signal, usually ranging from 6.95 to 10.77 ohms. 2 The signal from the amplifier to the 3500 is generally a voltage signal of around ±10V. 3 Is the signal that comes out of the 3500 the DO signal for triggering the vehicle to stop? There are two ways: one is for the 32-card module of 3500 to generate a DO signal internally, which is then sent to the ITCC; the ITCC subsequently sends another DO signal to trigger the shutdown. Another approach is for vibration, displacement, and other signal communications at 3500 to be sent to the ITCC, which then issues a DO signal to shut down the machine. 4 Vibration, displacement, speed, and phase signal from 3500 to DCS? It outputs a 4-20mA signal from the 3500 AO card to the DCS, which is used to display vibration, displacement, speed, and phase signals; communication cables are used for this purpose. The DS8000 is mainly used in generator sets, while the 3500 is primarily used in the chemical industry
I’ve learned it; the explanation is very professional and detailed
This method tool should be called a preprocessor, I guess
