Japan launched a long-term stability of the Vaisala excellent Digital Pressure Gauge
Vaisala (Vaisala, Headquarters: Tokyo) launched in April 2008 Digital Pressure Gauges “PTB330″. Determination of the range of 50 ~ 1100hPa, or 500 ~ 1100hPa. High-precision models can ± 0.15hPa accuracy determination. A year’s average error of ± 0.10hPa. Request for determination of accuracy and long-term stability of the industrial and aviation use. Specifically, high-precision measurement can be used to want to pressure of the occasion, such as using laser interferometer for measurement, as well as the engine testing in the exhaust gas analysis.
Products that can be embedded in a ~ 3 silicon capacitive absolute pressure sensor “BAROCAP”. If you use multiple sensors, pressure gauges, the determination of the value of the sensor can be compared with each other to determine whether the differences in the set of its range. In this way, can improve the reliability of measured values to easily grasp the pressure gauge to maintain and re-calibration date.
Measurement data not only to a numerical display, but also in order to observe trends in the charts. Chart in the observation process can be automatically updated. The use of special software, you can achieve data transfer to the PC.
