Vaisala PTB101B barometer barometric pressure sensor
Vaisala PTB101B Barometer Barometric Pressure Sensor Transmitter
The CS105 / PTB101B Barometer uses Vaisala's silicon capacitive sensor to measure barometric pressure over a 600 to 1060 millibar range. The CS105 / PTB101B outputs a linear signal of 0 to 2.5 Volts DC allowing it to be directly connected to Campbell Scientific dataloggers.
An integral circuit switches 12 volts from the datalogger to the barometer only during measurement, thereby reducing power requirements. Sensor warm-up and measurement time is one second minimum.
