JM-B-39 Integrated intelligent vibration protection transmitter
一,General
JM-B-39 integrated intelligent vibration protection transmitter is
an integrated, intelligent, high-protection vibration protection
transmitter. It can provide 4-20 mA current signal output, which is
proportional to the vibration speed or amplitude of the bearing
bush or bearing seat of the rotating machinery. At the same time,
it can also provide two-level switch output, TDM signal output,
etc. It automatically collects vibration signals on the machine and
uses the converted analog signals in PLC, DCS and DEH systems, etc.
二,Function
1. With a high degree of intelligence, the parameter setting
realizes the board operation.
2. It is highly integrated, easy to install and debug, suitable for
long-term online monitoring, and does not require on-site
maintenance.
3. Mainly used to measure the vibration of rotating machinery (ie,
tile vibration).
4. Secondary alarm switch output.
5. With 4-20mA current analog output.
6. With TDM interface output.
7. Set the alarm and dangerous values arbitrarily.
8. With self-check function.
9. With alarm self-locking function.
10. With large value automatic memory and query functions.
11. It is suitable for use in sites requiring explosion protection
and high protection.
