Baromètre numérique

• 500...1100 hPa or 50....1100 hPa pressure ranges with serial output
• Different scalings between 500...1100 hPa with analog output
• Electronics housing IP65 protected against sprayed water
• Accurate and stable measurement
• NIST traceable (certificate included)

For harsh environments

The Vaisala BAROCAP® Digital Barometer PTB210 is ideal for outdoor installations and harsh environments.

The barometers are designed to operate in a wide temperature range, and the electronics housing provides IP65 (NEMA 4) standardized protection against sprayed water.

The PTB210 barometers are ideal for use in applications such as weather stations, data buoys and ships, airports, and agrology. They are also an excellent solution for monitoring barometric pressure in industrial equipment such as laser interferometers and engine test benches.

Several pressure ranges

The PTB210 barometers are designed for various pressure ranges. They are available in two basic configurations: serial output for 500...1100 hPa and 50...1100 hPa and analog output with diff erent scalings between 500...1100 hPa.

Accurate and stable measurement

All the PTB210 barometers are digitally adjusted and calibrated by using electronic working standards. A higher accuracy barometer, that is fi ne-tuned and calibrated against a deadweight tester, is available for the 500...1100 hPa pressure range.

In addition, the PTB210 integrates directly with Vaisala Static Pressure Head Series SPH10/20. Th is pairing off ers accurate measurement in all wind conditions.

Vaisala BAROCAP® technology

The PTB210 barometers use the Vaisala BAROCAP® Sensor, a silicon capacitive absolute pressure sensor developed by Vaisala for barometric pressure applications. The Vaisala BAROCAP® Sensor provides excellent hysteresis and repeatability characteristics and outstanding temperature and longterm stability. All PTB210 barometers are delivered with a factory calibration certificate which is NIST traceable.

The PTB210 paired with the SPH10 Static Pressure Head.
