Bestech Australia presents the AD 1000/BA 1000 electronic barometer, from Halstrup. This barometer displays highly accurate and stable readings of absolute pressure (AD 1000) or barometric pressure (BA 1000).
This barometer is designed for displaying atmospheric pressure and absolute pressure in such areas as weather stations and airports.
At the heart of the unit is an evacuated CuBe chamber that contracts in proportion to barometric pressure. An inductive displacement transducer measures the movement of the chamber without making contact. The pressure port is led through in the AD 1000 for absolute pressure measurements.
These pressure sensors feature high accuracy and are stable for long periods. There is little zero point drift or hysteresis, and it is largely independent of temperature. The display can be adjusted to correspond to the height of the installation site.
Various measuring ranges and analog output signal types are available with this barometer/pressure transmitter, with many small ranges allowing for very high accuracies.
