Climatronics - Analog Barometric Pressure Sensor
Climatronics` analog barometric pressure sensor, P/N 102270 is designed for applications, which require accurate pressure measurements at a modest cost. It is a stable transducer based upon a proven design, yielding a linear and repeatable sensor with low hysteresis. The high level output signal is directly useable without additional signal conditioning.
This sensor features the use of a built-in Application Specific Integrated Circuit (ASIC), which works hand-in-hand with a capacitive transducer to achieve long-term stability and high accuracy. The analog pressure sensor`s small size and wide operating temperature range further enhance its compatibility with all of Climatronics` signal conditioning and data acquisition products.
Two measurement ranges (600 - 1100 hPa and 800 – 1100 hPa) and two accuracy specifications (0.1% and 0.25%) are available.
All versions of the P/N 102270 sensor are also available mounted in a small, vented environmental enclosure (NEMA-4X) for applications where another suitable shelter is not available. This assembly is provided under P/N 102272. Specifications for P/N 102270 and P/N 102272 are the same. The companion cable assembly for P/N 102272 is P/N101797-XX.
