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.

|*, **||* Defined as +/- 1 standard deviation from NIST traceable pressure reference. Includes non-linearity, hysteresis, repeatability, and calibration uncertainty.
** Defined as +/- 1 standard deviation from ideal analog output. Total analog output accuracy is the root sum square of digital accuracy, analog accuracy, and analog temperature dependence.
