DESCRIPTION

The Model 3310 is a battery powered, acceleration and thermal data acquisition system which provides sample rates of up to 4000 samples per second on each of its three acceleration axes. Its useful bandwidth ranges from DC to 500Hz. The 3310 contains three orthogonally mounted model 1010 digital capacitive accelerometers and utilizes a RISC microprocessor and a custom ASIC to automatically log AC/DC accelerations or AC velocities into its on-board flash memory. To reduce the amount of stored data, the user can record peak acceleration or velocity samples for selected time intervals or apply a root mean squared (RMS) algorithm to the data. Multiple windows of contiguous acceleration samples can also be recorded with each window center triggered on its acceleration threshold exceeding event.  The 3310 comes in a rugged, die cast aluminum case with an overall size of 3.5" x 4.5" x 2.2" and a weight of 29 oz. including batteries. A user's manual and 110VAC to 9VDC plug-in power adapter are included.

OPERATION

The Model 3310 is easily programmed via menu based 'mission' planning software running under Windows 95/98 on your personal computer. After downloading a mission to the 3310 via a supplied RS-232 serial cable connected to your PC's serial port, the 3310 can be disconnected and moved to the data collection site. An AC power adapter is included to power the 3310 during mission programming and data download if battery power needs to be conserved. Missions can be programmed to start immediately, after a delay, or at an absolute time/date with sequentially programmable data types and independent time durations. Total data acquisition time (depending upon acquisition rate and battery life) ranges from 300 seconds to 3 weeks. The data sample rate ranges from 1 per second to 4000 per second. The case can be mounted via two #8 screws, and the mounting screws can be tightened with the cover attached.

APPLICATIONS

SHIPPING DATA RECORDER
CRASH EVENT RECORDER
AUTOMOTIVE SUSPENSION TESTING   

    RACE CAR INSTRUMENTATION
   FLIGHT VIBRATION MONITOR
   ROTATING MACHINERY MONITOR

MISSION PROGRAMMING MENU

The main menu is a user friendly interface for planning data acquisition 'missions'. Mission parameters are entered as direct numeric values or selected via drop-down menus. An automatic 'mission tag' based on the serial number, start time and date is attached to each mission for foolproof mission and data identification.
