The Bal Pac 1200 is designed to measure vibration amplitudes as low as 1.0 micro inch displacement. The easy to read backlit display simultaneously displays both digital and bar graph readouts of the selected units (acceleration, velocity or displacement amplitudes). This unique combination yields the accuracy of a digital readout and the usability of an analog readout.
Vibration can be measured either full spectrum or at a specific R.P.M. with its tunable filter. Continuous manual frequency tuning employs automatic ranging from 72 to 720,000 C.P.M. The filter bandwidth is selectable between "narrow" and "wide" response or none. In addition, the Bal Pac 1200 has the ability to detect and analyze ultrasonic frequency vibrations to provide an early indication of bearing failure.
The Bal Pac 1200 can measure and plot a Vibration Power Spectrum over an operator selected specified range of frequencies. The stored record can be later displayed and downloaded to a computer for further evaluation.
With an optional photo-tach or laser-tach the Bal Pac 1200 can be used as a portable balancer. Upon completion of the easy 3-step calibration process the unit will display both amount and angle of unbalance for one or two planes. English and metric unbalanced data units are selectable by the operator. Selections include: oz-in, ft-lbs, g-mm, g-cm, kg-mm, or unbalance at the selected correction radius.
Included in the balancing software is a segmenting program, which will display the amount of correction required in two adjacent workpiece segments. This allows workpieces without a continuous surface (such as fans) to be balanced easily. This display indicates the segments to be corrected and unbalance amount at each segment. The balancer software can be setup to accommodate from 3 to 99 equally spaced segments.
The Bal Pac 1200 can be easily calibrated for almost all types of accelerometers, by simply inputting the mV/g rating of the pickup.
The Bal Pac 1200 is capable of storing a combination of up to 3000 individual vibration frequency readings and unbalance readings (amount and angles) while displaying the last 4. The unit will also store 1 plotted frequency spectrum while displaying another, allowing the operator to down load two plotted spectrums to a PC at a time. A serial RS-232C compatible port is provided to download data to a PC or attached to a printer for hard copy printout.
The analyzer is completely portable, powered by readily available camcorder batteries that can be changed by the user. High quality Nickel-Metal Hydride batteries are used because they do not require a full discharge and complete charge in order to maintain battery capacity. In other words they do not have the "memory effect" that is commonly found on less expensive Nickel-Cadmium batteries. A bar graph is used to display the Bal Pac 1200 battery strength. The analyzer and optional strobe are powered separately with different battery types so even if the strobe battery is discharged, the analyzer portion is still fully functional.
The Unit is supplied complete with a hard carrying case, 1 battery, battery charger, one velocity transducer with mounting magnet, cable and 2 probes. Please note the photo-tach, laser-tach or strobe light may be purchased now or at a later date and merely "plugged in".
