The PTB110 Barometer is designed both for accurate barometric pressure measurements at room temperature and or general environmental pressure monitoring over a wide temperature range. It uses Vaisala''s BAROCAP(R) silicon capacitive sensor to measure barometric pressure over a 500 to 1100 millibar(hPa) range with an output of 0 to 2.5v and a low current consumption, making it suitable for use with a wide range of data loggers.
Features:
> Accuracy of +/-0.3 mb� (hPa) @ +20 degC
> Long-term stability +/-0.1 mb (hPa) per year
> Output voltage 0 to 2.5VDC = 500 to 1100 mb (hPa)
> Current consumption less than 4mA
> On/off control with external trigger
> Mountable on a 35mm wide DIN rail
> NIST traceable calibration (certificate is included)
The PTB110 is a popular choice for wind-assessment and general-meteorology applications where a barometer is required.
