CHAPTER 2
PRODUCT DESCRIPTION
The PTB210 series digital barometers are designed for various
pressure ranges. The barometers with an analog output are available
with different scalings between 500 ... 1100 hPa for 0 ... 5V or
0 ... 2.5V. The PTB210 series barometers are also available with a
digital output.
The PTB210 series barometers offer an excellent solution for outdoor
installations. They operate in a wide temperature range. The housing
of the barometer electronics provides an IP65 standardized protection
against sprayed water. The rugged corrosion-resistant housing in
combination with the small size facilitates easy installation and a long
lifetime for the barometer.
All the barometers are digitally adjusted and calibrated by using
electronic working standards.
This manual gives the instructions for the use of PTB210 barometers
with the analog output.

The PTB210 barometers incorporate the BAROCAP®silicon
capacitive absolute pressure sensor developed by Vaisala. The sensor
features excellent hysteresis and repeatability characteristics and has
an outstanding temperature and long-term stability.

Figure 2 The BAROCAP® Pressure Sensor
The BAROCAP® pressure sensor consists of two layers of single
crystal silicon having a layer of glass between them. The thinner
silicon layer creates an integrated vacuum reference chamber, and
forms a pressure-sensitive silicon diaphragm. The thicker silicon layer
is the rigid base plate of the sensor, and it is clad with a glass
dielectric. Thin film metallization has been deposited to form a
capacitor electrode inside the vacuum reference chamber. The other
electrode is the pressure-sensitive silicon diaphragm.
The coefficients of thermal expansion of silicon and glass materials
used in the BAROCAP® pressure sensor are carefully matched
together to minimize the temperature dependence, and to maximize
the long-term stability. The BAROCAP® pressure sensor is designed
to achieve zero temperature dependence at 1000 hPa, and its long-term
stability has been maximized by thermal ageing at an elevated
temperature.
