SENSOR PRODUCTS Honeywell Precision Barometer APPLICATIONS Remote Meteorological Stations Data Buoys HPB Environmental Data Logging T General Meteorology Altimeters Airborne Measurements Airports he Honeywell Precision Barometer offers outstanding value to instrument builders requiring accurate and stable barometric measurements in real-world conditions. The HPB uses proven silicon sensor technology with microprocessor-based signal compensation, eliminating the need to insulate or temperature-regulate the barometer. The HPB has a pressure range of 500 to 1200 hPa. The HPA, intended for altimeter applications, provides a pressure range of 0 to 17.6 psia. ISO 9001 FEATURES AND BENEFITS High Accuracy from -40 to 85C: Two-tiered accuracy including temperature errors over -40 to 85C: HPB, 0.4 hPa or 0.8 hPa; HPA, 0.03% or 0.06%FS maximum. Simplifies system design--no need to insulate, temperature-regulate or provide additional signal compensation.
