Data logging for digital pressure calibration test gaugesA new data logging feature for BetaGauge PI and BetaGauge PI Reference Class digital pressure calibration test gauges is available in concert with the new BetaLOG data logging software application. BetaLOG is the high performance answer for pressure data logging applications. Whether the need is to log data on one BetaGauge PI or 100, the easy to use, low cost application handles the entire requirement. BetaLOG configures the gauge to operate in demand ad-hoc mode (field configuration) or download mode (computer configuration) for complete flexibility in configuring the data logging application. A unique feature of the BetaLOG/BetaGauge combination is the ability to simultaneously record ambient temperature along with pressure. This feature facilitates the performance of hydrostatic testing where the relationship of temperature data to pressure data is critical. Using the download operational mode allows a wide range of configuration settings, including multiple interval selection options from 1 second to 1 hour. Data logging runs can range from only a few seconds to several weeks. Four types of data capture mode allow the user to log either all data or only the points of interest. The types of capture available are continuous (log all data at defined intervals), data high (log data at defined intervals only when it rises above a preset value), data low (log data at defined intervals only when it falls below a preset value), and delta trip (for detecting noise or transients in the pressure signal). The number of data points to be recorded (up to the maximum of 9520 points) is also user selectable. Six types of data can be collected: interval end, average, minimum, maximum, median and a combination type of average/minimum/maximum. When set to demand mode data logging, the user can easily set up and initiate data logging in the field using the BetaGauge PI keypad with a few easy key presses. The field is where BetaGauge PI excels with its rugged stainless steel rubber booted housing, durable Lexan® faceplate, IP 65 rating and extremely long battery life. It is also CSA and ATEX rated for use in hazardous areas. The BetaGauge PI supports multiple data sets. Data sets can be mixed between Demand mode and Download mode as needed.
