YOUNG Barometric Pressure Sensor 61402


The Model 61402 Barometric Pressure Sensor offers unparalleled performance and flexibility for atmospheric pressure measurement.

The YOUNG Barometric Pressure Sensor 61402 combines high accuracy and low power consumption over a wide pressure range (500 to 1100 hPa) and temperature range. Its compact size allows for easy placement in most standard enclosures. The barometer is available in two configurations to meet a variety of application needs:

Model 61402V provides 0-5 VDC and RS-232 outputs

Model 61402L provides 4-20 mA, RS-232, RS-485, and SDI-12 outputs.

For outdoor installation, the Model 61360 Weatherproof Enclosure and Model 61002 Pressure Port are recommended.

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