-
mitter is the latest version of an established
series of transmitters from Metrix. The
ST5491E is the indicating version of Metrix
Model ST5484E and comes with an integral
2-1/2 digit LCD indicator for local vibration
readout. It incorporates state-of-the-art
electronic components and circuits. It also
offers several new options in terms of fea

tures and configurations.
The transmitter combines a vibration sensor
and signal conditioner in a single package.
They provide the ideal solution for sensing
machinery vibration level and transmitting
a proportional 4-20 mA signal directly to a
PLC, DCS, monitor, or computer. Typical ap
-
plications include low- and medium-speed
machines such as fans, blowers, pumps, mo
-
tors, and centrifuges. The transmitter can
be supplied with optional screw cover elbow
fittings for connecting flexible conduit.
The transmitter is all solid state, has no
moving parts, and is encapsulated in a
stainless steel housing. The LCD indicator
is packaged in a sealed module that can be
positioned in 90° increments with the elbow
fitting to allow proper viewing when the
transmitter is installed. Each transmitter is
factory calibrated to the sensitivity marked
on the label.
