MeasuringPAD is designed to fulfill a twofold task:
With this twofold function in mind, it's easy to see the kinds of applications for which this instrument is ideal. Foremost are maintenance and troubleshooting applications, including not only routine preventative or emergency equipment service, but also monitoring the daily or intermittent performance of plant systems for energy, heating and cooling, exhaust, material handling, and so on. Fault recording ("event" monitoring of problematic machine or process parameters for detailed post-analysis) is an important aspect of troubleshooting, as is trend analysis for off-line SPC/SQC. A service technician can, for example, quickly set up a MeasuringPAD unit with appropriate parameters and trigger limits to perform the high-speed sampling necessary to detect a subtle timing or signal amplitude fault. MeasuringPAD
can also prove its worth in periodic process tuning
operations, such as checking vibration, calibration, setpoints, process flow,
servo/control-loop timing and actuation, machine settings and benchmarking.
The basic portability of the instrument is of great advantage in all
kinds of laboratory and test-chamber measurements,
"remote-site" testing, and
field service applications,
including hard-to-reach locations and even on-board vehicle performance
logging. For example, energy surveys in motors, appliances, and HVAC equipment are a natural for MeasuringPAD, since electric consumption can be easily measured and compared to performance standards. In the case of benchmarking or troubleshooting an installed compressor/refrigeration system, the unit can readily monitor the input power AC signals and, using its limit-sensitive triggers, detect and capture any adverse voltage sags or swells. At the same time, it can perform temperature profiling of the system, thereby monitoring its on/off control and cooling efficiencies. Because of the speed of acquisition and minimal latency between input parameters, MeasuringPAD can handle other critical parameters such as compressor vibration, refrigerant pressure, and open/closed switch status. It can then plot recovery profiles for predictive maintenance and improved system control. With its ability to handle configurable DFT measurements for amplitude vs. frequency, MeasuringPAD can serve as a cost-effective tool for high-speed spectrum analysis (as, for example, in the monitoring of bearing wear on the production line), at the very same time that it's measuring and recording typical "shop-floor" variables like speed, flow, and pressure.
