MODEL TB-2012M BAROMETRIC PRESSURE SENSOR
(Shown with cover removed)
DESCRIPTION
The Texas Electronics, Inc. TB-2012M Barometric Pressure Sensor uses an active solid-state device to sense
barometric pressure. Self-contained electronics provide a regulated voltage to the solid-state sensor and
amplification for the signal output. The unit's range of 26" to 32" or 878 mb to 1080 mb of mercury allows it to
be used at elevations up to 1800 feet or 548.64 meters above sea level. The unit is temperature compensated
from -18° to +50°C. if elevations above 1800 feet or 548.64 meters are required, contact the factory for higher
elevation calibration.
