Machine protection and condition
monitoring specialist, Sensonics, has
enhanced its range of DN803X series
shaft vibration and thrust position
transmitters following approval for
intrinsically safe applications.

The DN8031 (vibration) and
DN8033 (thrust position) proximity
probe systems are now suitable for
Ex ia IIC T4 applications when used
in conjunction with Sensonics ATEX
approved range of AECP proximity
probes and AEXC extension cables.

The 4-20mA loop powered
modules provide easy integration
with either the local machine PLC or
a plant-wide DCS since it is powered
through the safety barrier
measurement loop. Signal processing
is carried out within the unit giving
an output current proportional to
either peak-to-peak shaft vibration
or relative position to the probe face.

The module permits adjustment of
both gain and offset for ease of
calibration to suit the application.
