VIBRATION TRANSMITTER
TR-26
The integrated transmitter TR-26 measures the absolute vibrations of any
rotating machine support and it is able to interface directly in 2 wires technique
(current loop 4 ÷ 20 mA) to an acquisition system (PLC or DCS).
The transmitter, secured directly on machinery, generates an electric signal (4÷20 mA) which is proportional respectively to vibration velocity or
acceleration. The transmitter is made of an AISI 316L body with machine connection thread; the connection to the acquisition system is effected by
means of a MIL-C-5015-2 poles connector.
NOTE: The transmitter is available in different configuration versions and does not need any set-up or maintenance.
The transmitter is certificate SIL 2 for functional safety..
The transmitter is certified for application in classified area as
