About this file
This is a technical specification document for the Vaisala BAROCAP Barometer PTB110, an industrial barometric pressure measurement device. The document details the features and capabilities of the barometer, which is designed for accurate pressure measurements at room temperature and environmental pressure monitoring across wide temperature ranges. The device features the Vaisala BAROCAP sensor, offers multiple pressure ranges from 500-1100 hPa, provides accuracy of ±0.3 hPa at +20°C, and includes on/off control with external trigger.
The PTB110 operates on 10-30 VDC with power consumption of 0.10W at 12V, offers output voltage options of 0-2.5 or 0-5 VDC, and output frequency of 500-1100 Hz. It features mechanical specifications including IP32 rating, dimensions of 97.3 × 68.4 × 28.1 mm, and weighs 90g. The device is constructed with a plastic ABS/PC blend housing cover and aluminum mounting plate, can be mounted on 35mm wide DIN rail, and includes a traceable calibration certificate. The barometer demonstrates excellent long-term stability of ±0.1 hPa/year and is suitable for applications including environmental pressure monitoring, data buoys, laser interferometers, and agricultural/hydrological uses.

Vaisala BAROCAPâ Barometer PTB110 is designed both for accurate barometric pressure measurements at room temperature and for general environmental pressure monitoring over a wide temperature range.
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.
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.
Accuracy and Stability The excellent long-term stability of the barometer minimizes or even removes the need for field adjustment in many applications.
