Vaisala BAROCAPâ Digital Barometer PTB210 is a reliable outdoor barometer for harsh conditions.

For harsh environments PTB210 is ideal for outdoor installations and harsh environments. PTB210 is designed to operate in a wide temperature range, and the electronics housing provides IP65 (NEMA 4) standardized protection against sprayed water.

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

Several pressure ranges PTB210 is designed for various pressure ranges. It is available in 2 pressure ranges in 3 configurations:

• Serial output for 500 … 1100 hPa

• Serial output for 50 … 1100 hPa

• Analog output with different scalings between 500 … 1100 hPa

Accurate and stable measurement PTB210 is digitally adjusted and calibrated by using electronic working standards. A higher accuracy barometer, which is fine-tuned and calibrated against a high-precision pressure calibrator, is available for the 500 … 1100 hPa pressure range.

In addition, PTB210 integrates directly with Vaisala Static Pressure Head Series SPH10/20. This pairing offers accurate measurement in all wind conditions.

Vaisala BAROCAP technology PTB210 uses 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 long-term stability.

PTB210 is delivered with a traceable factory calibration certificate.
