YOUNG barometric pressure sensors combine high accuracy and low power consumption over a wide range of pressures (500 to 1100 hPa) and temperatures. The compact size allows easy placement in most standard enclosures. The barometer is available in two configurations to satisfy a variety of applications:
Model 61402L offers 4-20 mA, RS-232, RS-485 and SDI-12 outputs.
For outdoor installation, Model 61360 Weatherproof Enclosure and Model 61002 Pressure Port are recommended.
