Bộ chuyển đổi tin hiệu rung động PROVIBTECH TM301-A00-B01-C00-D00-E00-F00-G00

TM301 can be directly connected with various types of eddy current probes. The TM301 has significant features that are different from other TM transmitter tables. The TM301 does not require an external preamplifier, it has a built-in preamplifier, which simplifies the operation procedure, and its reliability is improved due to the reduction of monitor components.

TM301 outputs the standard 4-20mA current signal, correspondingly reflects the monitoring of shaft vibration. Like other TM monitoring meters, TM301 can also directly drive two-level alarm relays, and can maintain the "alarm" and "interlock" indication states.
