TR-I Vibration Transmitter
Explosion-proof vibration transmitter
The integrated transmitter TR-I 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. The Signal is proportional to vibration velocity or acceleration.
TR-I-ATEX is made of a stainless steel body AISI 316L with machine connection thread and it is supplied with a die-casted aluminium case for the terminal board with ¾” NPT female thread.
The transmitter is certified for classified area:
