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.
