230-61402 Series Barometric Pressure Sensors

SKU: 230-61402-CONFIG Categories: , Tags: , , ,

The 230-61402 Series Barometric Pressure Sensors offer unparalleled performance and flexibility for atmospheric pressure measurement. The barometer is available in two configurations to satisfy a variety of applications; Model 230-61402L provides a 4-20 mA current output, 230-61402V provides 0-5 Vdc output. Both models offer serial output in addition to the analog signal.

The 230-61402 Series Barometric Pressure Sensors offer unparalleled performance and flexibility for atmospheric pressure measurement. They combine high accuracy and low power over a wide range of pressures and temperatures. The 230-61402 BP Sensor with back plate can be mounted in a NovaLynx data logger enclosure or protected in a weathertight polycarbonate enclosure.

230-61402V

  • Calibrated 0-5 Vdc analog output (Jumper selectable 0-2.5 Vdc)
  • Analog current consumption is less than 4 mA. A special “sleep” mode further reduces current draw to a few μA.
  • RS232 serial output included

230-61402L

  • Standard 4-20 mA output (Programmable 0-20 mA)
  • User selectable serial interfaces SDI-12, RS-232, RS-485

230-61002 Pressure Port Accessory

Measurement performance of remote barometers can be seriously impaired by the effects of wind at the barometer inlet. Ambient wind of 20 meters/second blowing over a typical barometer inlet tube can cause dynamic pressure errors as high as 3 mbar. These errors can make atmospheric pressure data useless for research and forecast purposes. The 230-61002 Pressure Port reduces dynamic pressure errors to a minimum.

* 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.
