VIBRATIONS TRANSMITTER mod. Ex TR-26

Function

The integrated transmitter mod. Ex TR-26 measures the Absolute Vibrations of any rotating

machine support and is able to interface itself directly (two-wires technique, current loop 4 to 20

mA) with an acquisition system (PLC or DCS).

The transmitter reduces at maximum installation and wiring incidence, that normally limits the

possibilities to apply the traditional systems for vibration monitoring.

The transmitter is certified for applications in areas classified as:

- Ex II 2 G Ex ia IIC T6 or T5 or T4

General description

The transmitter, assembled through direct fastening on the machinery, generates a current signal (4

to 20 mA) that is proportional respectively to vibration speed or acceleration.

The transmitter is composed of a stainless steel body having a threaded machine connection; the

connection with the users is performed by means of a MIL-C-5015 connector (2 poles), included.

NOTE: The transmitter is available in different configurations and becomes operative only after its

correct electrical connection, as per drawing no. 85465-P; it doesn’t need setup or maintenance.
