FREE OMEGA™ Downloadable Software!
Free OMEGA PC software takes the data from the transmitter directly to the digital domain, turning your laptop or Windows® tablet into a virtual meter, chart recorder, or data logger. Also included are .NET APIs and a command set for command-line access. Download your free copy today! Note: RS485 to PC interface is required, sold separately Charting Window – The addition of a charting window allows you to see your data graphed in real time. The Y axis is configurable to allow simultaneous graphing of multiple engineering units. You can output the image of your data to a png file.
Channels Window - Display data from all of your sensors simultaneously. Each channel has configurable user alarms, three data filters, tare, resettable low/high indication, and sample rates ranging from 30 minutes to 640Hz.
Logging Window – A new xls filetype output option presents preformatted data for readability. In addition, Live Statistics are displayed, including the sensor information, the start/stop time, the number of samples taken, the current reading, and the High/Low readings. With the logging window, you can capture your data for later analysis.
The PX409 RS485 Series is an industrial RS485
Silicon Pressure sensor. Use stand-alone for up to
640 Hz sampling rate, or connect up to 16 units in
an independent multidrop RS485 network at 1 Hz
overall bus sampling rate. Interface to the sensor
using command line access, or use OMEGA’s
Free PC software to chart, log, display, and output
data for analysis. An additional analog output (0 to
5V, or 4 to 20 mA) provides even more flexibility.
The micro-machined silicon design is ideal for
pressure or level applications in laboratory, test
platforms, or bio/pharmaceutical applications as
well as industrial applications that require a rugged,
high accuracy transmitter that can transmit over
long distances. The micro-machined silicon sensor
provides a very stable transmitter with exceptional
high accuracy of ±0.08% and a broad compensated
range of -29 to 85°C (-20 to 185°F). The modular
construction allows for fast delivery of most
configurations and fittings.
