About this file
This technical data sheet from Vaisala details specifications for the BAROCAP Barometer PTB110, which is being procured by the Texas Water Development Board (TWDB) under solicitation #580-25-IFB-3461 for 30 units across Travis County and Austin City jurisdictions. The PTB110 is an industrial barometer designed for accurate pressure measurements at room temperature and environmental monitoring across wide temperature ranges. The device features multiple pressure range options from 500-1100 hPa, output voltage of 0-2.5V or 0-5V, and frequency output of 500-1100 Hz. Bids must be submitted by February 24, 2025, at 2:00pm Central Time, with a question and answer period running February 18-25.
The barometer utilizes Vaisala's BAROCAP silicon capacitive sensor technology and offers accuracy of ±0.3 hPa at +20°C with excellent long-term stability of ±0.1 hPa/year. Technical specifications include IP32 rating, operating temperature range of -40 to +60°C, power consumption of 0.10W at 12V, and dimensions of 97.3 × 68.4 × 28.1 mm. The device is mountable on 35mm DIN rail and includes features like external On/Off control and traceable calibration certification. The procurement follows FOB Destination freight terms and Net30 payment terms, with no specific budget range disclosed. Only exact conforming bids for the specified model will be considered under Texas Government Code Section 2155.067.

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.
