Product Details

I. Overview

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 rotating machinery bearing pad or bearing housing. At the same time, it can also provide two-level switch output, TDM signal output, etc. It automatically collects the vibration signal on the machine, and uses the converted analog signal for PLC, DCS and DEH systems, etc.

Two, function

1. It is highly intelligent, and 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. It is 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. Alarm and danger value can be set arbitrarily.

8. With self-test function.

9. With alarm self-locking function.

10. With large value automatic memory, query function.

11. It is suitable for use in sites requiring explosion-proof and high protection.
