CEMB USA TR-P - Manuale

TR-P
VIBRATION TRANSMITTER
Function
The integrated transmitter TR-P 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).

GEnErAL DEScriPtion
The transmitter, secured directly on machinery, generates an electric signal (4÷20 mA) which is proportional to vibration velocity or acceleration.
The transmitter is made of a stainless steel basis AISI 316L with machine connection thread and a polyamide molded body; the connection to the
acquisition system is effected by means of a TE CONNECTIVITY SUPERSEAL connector. The peculiar characteristics of the polyamide construction
and of the connection allow unique resistance to extreme ambient conditions, enabling an IP67 protection degree.
NOTE: The transmitter is available in different configuration versions and it does not need any set-up or maintenance.
