iT300
4-20 mA congurable vibration
transmitter module
Key features
• Accepts input from
accelerometers (single or
dual output) or piezovelocity
sensors
• Input signal is split into
two independent processing
bands
• Measures real-time sensor
bands, BOV, true peak and
temperature (if applicable)
• Built-in web server for
custom conguration of
bandwidth/detection type
• 2 x 4-20 mA outputs, user-
dened
• Text eld for user entry of
machine information
• Congurations can be stored
• Selectable speed range
• Manufactured in an
approved ISO 9001 facility
The iT300 transmitter provides an easy means to connect a standard IEPE vibration
sensor to a PLC, DCS or SCADA system. The transmitter’s input provides power
to and measures the signal from either an accelerometer, piezovelocity sensor or
dual output sensor. The input circuitry has a wide frequency response, capable of
measuring signals between 0.2 Hz and 20,000 Hz.
The transmitter has two
independent processing bands
with exible mapping options
to two separate 4-20 mA
analog outputs. The processing
channels contain selectable
integration, allowing input from
accelerometers to be output
as acceleration or velocity.
Selectable band lters and
detector types make it easy to
tailor the processing to specic
machines or applications.
