The OM-DAQPRO-5300 series has been discontinued. Please check the new OM-CP-OCTPRO as an upgraded replacement.

The OM-DAQPRO-5300 is an eight-channel portable data acquisition and logging system with graphic display and built-in analysis functions.The datalogger is powered by an internal rechargeable battery and is capable of sampling,processing and displaying measurements without being connected to a computer. The OM-DAQPRO-5300 is a professional,cost-effective, compact and stand-alone data logging system that can be used with a wide variety of applications. This 16-bit, high-resolution, eight-channel datalogger has graphic displays and analysis functions for measuring voltage,current and temperature in real-time. With its high resolution and fast analog to digital converter (ADC), the OM- DAQPRO-5300 meets the majority of data logging requirements in most industrial applications. Its unique ability to display measured values and analyze them in real- time on a graphical interface minimizes the need to download collected data to a computer for further analysis. Every OM-DAQPRO-5300 datalogger is embedded with a unique serial number and can be loaded with a descriptive comment for safe identification.

The datalogger is very easy to use because all its functions are broken down into an 8-icon menu.The four buttons on the datalogger ’s front keypad can be used to browse every menu and execute any of the commands.

The OM-DAQPRO-5300 has eight input channels for measuring voltage, current, temperature and pulses. User selectable input types/ ranges are 0 to 24 mA, 0 to 50 mV, 0 to 10 V, 2252 Ω or 10 K Ω thermistors, PT100 RTDs, type J, K or T thermocouple temperature sensors, internal temperature, pulse counter, frequency meter and up to 20 user defined sensors (used for scaling analog voltage or current inputs in engineering units).

The OM-DAQPRO-5300 can record data from up to eight 2-wire or four 3-wire PT100 RTD inputs (two input channels are required for each 3-wire PT100 RTD input connected).Frequency/pulse counter is only available for input 1.

The datalogger provides a simple and straight forward tool for defining up to 20 custom sensors. Almost any 0 to 10 V and 4 to 20 mA sensor or transducer can be displayed and scaled in meaningful engineering units, e.g., psi or gpm. The sensor definitions are stored in the datalogger ’s memory and are added to the sensors list. The sensor ’s readings are displayed in the user-defined units both on the OM-DAQPRO-5300 ’s LCD screen and the Windows software.

The inputs use pluggable screw terminal blocks for easy connection. An internal clock and calendar keeps track of the date and time of every sample measured.

The OM-DAQPRO-5300 can automatically activate an external alarm device, e.g., energize an audible alarm or turn on a warning light,when an input channel is outside a specified range (Input/Output 8 serves as either an input or an alarm output). The external alarm device (audible or visual alarm) is connected to the screw terminals of Input/Output 8. The alarm output is an open collector output which is analogous to an electrical switch. High/low alarm levels and also whether or not the alarm output is activated during an out-of limit condition can be set for each input channel individually.

DAQLAB Windows Software The OM-DAQPRO-5300 system also comes with DAQLAB, a powerful Windows software. When the datalogger is connected to a PC, live displays can be viewed at rates of up to 100 samples/sec, and automatic downloads can be carried out at higher rates.

The software can display the data in graphs, tables or meters, can analyze data with various mathematical tools, or export data to a spreadsheet. The Windows Software also enables you to set up the datalogger and to send advanced commands such as alarm settings, triggering conditions and text notes.
