Precision Barometers

Barometric Transducer Solutions

Honeywell barometers are used to measure barometric pressure in a wide variety of meteorological and aerospace applications such as manned and unmanned vehicles, ocean data buoys, remote meteorological stations, airborne measurements and weather balloons.

Honeywell's precision barometer and precision altimeter have the best combination of accuracy and stability due to the integration of a microprocessor with Honeywell's Micro-Electro-Mechanical Systems (MEMS) silicon pressure sensor. The MEMS sensor in Honeywell’s precision barometers is compensated from -40 to 85 °C, using a microprocessor to compute data to accuracies within ±0.03 percent of the full-scale pressure range.

The Honeywell Precision Barometer (HPB) and Honeywell Precision Altimeter (HPA) offer RS232, RS485 or TTL digital outputs..
