The DTM10 distributed vibration transmitter-monitor is ideal for monitoring machine vibration using proximity probes and a Modbus interface to a PLC or DCS system. The DTM also contains redundant power supplies and redundant 4-20mA transmissions. Using PVTVM’s unique strategy, the DTM can interface with almost any proximity probe system without hardware changes.
