The middle subject heap are medium weights (probably real baseballs), while these in the seats are undoubtedly lightweights (maybe Wiffleballs?). In effect now we have invented a weighing machine that determines mass from the item's trajectory in a crossing field. Can we use gravity as the crossing area for atoms and molecules? The petrochemical, gasoline processing, газоанализатор biogas, landfill and gas pipeline industries has always wanted an correct and dependable, low maintenance and price efficient CO2 analyzer for quality and process management purposes. KECO has met these requirements with the proven microprocessor primarily based analyzer. The CarbonHound supplies continuous on-line analysis based on the precise non-dispersive infrared principle of operation. 1.5 SCFH. Next, the pattern is launched to the particular infrared detection aspect that gives an output proportional to the concentration of carbon dioxide. This sign is digitized and analyzed by the superior microprocessor HMI (Human Machine Interface) and associated software program resulting in a 4-20 mA output, relay alarms, and RS-485, TCP/IP Ethernet.

VERSATILE INTERFACING — by means of TCP/IP, RS-232, USB, analog & digital I/O, and/or optionally available Bluetooth. Home SERVICE AND Assist Center — our US-primarily based gas analyzer service, upkeep, repair, and calibration heart is based in Cincinnati, OH. This central location makes product assist handy and helps with quick turnaround time and environment friendly delivery. The ULT collection is a simplified design for much less demanding applications. The UGA system makes use of a two-stage stress decreasing inlet to pattern gases at atmospheric strain. After the strain is lowered to round 10-6 Torr, the gas stream is distributed to a mass spectrometer (residual fuel analyzer—RGA) which measures the focus of each mass of curiosity. This instrument is a self-contained analyzer for measuring trace quantities of a chosen fuel utilizing diode laser optical absorption with wavelength modulation spectroscopy (wms) detection. The analyzer is fully automated upon energy-up. A LabView-based program is supplied to read, show, and log gas concentration, temperature and pressure measurements, and instrument diagnostic codes on the consumer's computer. Readout is by way of a USB port configured for serial transmission and is offered for consumer-personalized data acquisition programs. The basic unit requires user-supplied sampling traces.
