Documentation Conventions
Throughout the manual, important safety considerations are
highlighted as follows:
WARNING Warning alerts you to a serious hazard. If you do not read and follow
instructions very carefully at this point, there is a risk of injury or
even death.
CAUTION Caution warns you of a potential hazard. If you do not read and
follow instructions carefully at this point, the product could be
damaged or important data could be lost.
NOTE Note highlights important information on using the product.

Safety
The product delivered to you has been tested for safety and approved
as shipped from the factory. Note the following precautions:
WARNING Ground the product, and verify outdoor installation grounding
periodically to minimize shock hazard.
WARNING To avoid electric shock, never open the PTB330 enclosure while the
transmitter is connected to mains power.
CAUTION Do not modify the unit. Improper modification can damage the
product or lead to malfunction.
ESD Protection
Electrostatic Discharge (ESD) can cause immediate or latent damage
to electronic circuits. Vaisala products are adequately protected
against ESD for their intended use. However, it is possible to damage
the product by delivering electrostatic discharges when touching,
removing, or inserting any objects inside the equipment housing.
To make sure you are not delivering high static voltages yourself:
- Handle ESD sensitive components on a properly grounded and
protected ESD workbench. When this is not possible, ground
yourself to the equipment chassis before touching the boards.
- Ground yourself with a wrist strap and a resistive connection cord.
- When neither of the above is possible, touch a conductive part of
the equipment chassis with your other hand before touching the
boards.
- Always hold the boards by the edges and avoid touching the
component contacts.

CHAPTER 2
PRODUCT OVERVIEW
This chapter introduces the features, advantages, and the product
nomenclature of PTB330.
Introduction to PTB330
Vaisala BAROCAP®Digital Barometer PTB330 provides reliable
pressure measurement in a wide range of applications. Digital outputs
RS-232 (standard) or RS-422/485 (optional) can be selected.
Alternatively, analog outputs can be chosen between current and
optional voltage signals. A local graphical display is available as well.
The quantities measured and calculated by PTB330 are presented in
Table 2 on page 15.
The PTB330 barometer is available with one, two, or three barometer
modules. The barometer can be used successfully both in accurate
pressure measurement applications at room temperature and in
demanding automatic weather station applications.
USER'S GUIDE____________________________________________________________________
14 __________________________________________________________________ M210855EN-D
Basic Features and Options
- Applicable in industrial and meteorological areas
- Calculated aviation related output quantities: QFE and QNH
- 1 ... 3 BARO-1 barometer modules (sensors)
- Barometer mounting accessories for multiple installation purposes
- Service port for MI70 Link Interface Software or PC
- Four module slots
- IP 65 housing
- Screw terminal, optional M12 connector or D-9 connector
- Optional graphical display showing the measurement trends of the
quantities chosen by the user
- Optional modules: power supply module, RS-485 module, analog
output module, and relay module
- Optional USB cable for service use or data transfer
Pressure Measurement
The PTB330 series barometers use a BAROCAP®silicon capacitive
absolute pressure sensor developed by Vaisala for barometric pressure
measurement applications. The BAROCAP®sensor has excellent
hysteresis and repeatability characteristics, low temperature
dependence, and a very good long-term stability. The BAROCAP®
sensor is very robust and resistant to mechanical and thermal shocks.
The measurement principle of the PTB330 series digital barometers is
based on an advanced RC oscillator and reference capacitors against
which the capacitive pressure sensor is continuously measured. The
microprocessor of the barometer performs compensation for pressure
linearity and temperature dependence.
Each barometer module in PTB330 has its own adjustment
coefficients for different reference pressures across the entire
temperature range. This achieves the best possible accuracy needed in
barometric pressure measurements.

Wall Mounting with Wall Mounting
Kit
When mounting with wall mounting kit the mounting plate (Vaisala
order code 214829) can be installed directly on wall or onto a standard
wall box (also US junction box). When wiring through back wall,
remove the plastic plug from the wiring hole in the barometer before
mounting.
