PTB110 Barometer

The PTB110 barometer is a micro controller based barometer including a voltage or frequency output. The barometer can be supplied with several pressure ranges. The output of the barometer is a calibrated barometric pressure reading. The barometer uses the Vaisala BAROCAP® Sensor, a silicon capacitive sensor developed by Vaisala for barometric pressure measurement applications. The BAROCAP® sensor is especially designed for accurate and stable measurement of barometric pressure. 

Vaisala BAROCAP Technology 

PTB110 uses the Vaisala BAROCAP sensor, a silicon capacitive absolute pressure sensor developed by Vaisala for barometric pressure measurement applications. The sensor combines the outstanding elasticity characteristics and mechanical stability of single-crystal silicon with the proven capacitive detection principle. 

Accuracy and Stability 

The excellent long-term stability of the barometer minimizes or even removes the need for field adjustment in many applications.

Applications 

PTB110 is suitable for a variety of applications, such as environmental pressure monitoring, data buoys, laser interferometers, and agriculture and hydrology. The compact PTB110 is ideal for data logger applications as it has low power consumption. The external On/Off control is practical when electricity supply is limited.
