Product Related Safety Precautions
The product delivered to you has been tested for safety and approved as
shipped from the factory. Note the following precautions:
WARNING
CAUTION
Ground the product, and verify outdoor installation grounding
periodically to minimize shock hazard.
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 1 on page 18.
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.
Basic Features and Options
- for applications in industrial and meteorological areas
- 1...3 barometer modules (sensors)
- graphical display showing the measurement trends of the quantities
chosen by the user
VAISALA_______________________________________________________________________ 17
User's Guide ______________________________________________________________________
- user friendly, multilingual display
- calculated output quantities, QFE and QNH, available
- barometer mounting accessories for multiple installation purposes
- service port for MI70 Link Interface Software or PC
- four module slots
- optional modules: power supply module, RS-485 module, analog
output module and relay module
- optional USB cable
- IP 65 housing
- screw terminal, optional M12 connector or D-9 connector
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 ruggedness of the
BAROCAP® sensor is outstanding and the sensor is 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.

Panel Mounting Frame
To enable a neat and dirt free embedded installation of the transmitter,
a panel mounting frame is available as an option (Vaisala order code:
216038). The frame is a thin, flexible plastic frame for the transmitter,
with adhesive tape on one side.The frame is used to hide any rough
edges of the installation hole, and provide a more finished look. Note
that the panel mounting frame is not intended to bear the weight of the
transmitter, and does not include any mounting supports.
Use the panel mounting frame as follows:
1. Use the frame as a template to mark the required size for the
installation hole in the panel.
2. Cut the hole in the panel.
3. Mount the transmitter through the panel with suitable supports.
4. Remove the paper protecting the adhesive tape on the frame, and
attach the frame around the transmitter. Refer to Figure 13 on page
27 below.

General about Wiring and Grounding
Cable Bushings
A single electrical cable with a screen and three to ten wires is
recommended for power and signal connections. The cable diameter
should be 8...11 mm. The number of cable bushings depends on the
barometer options. See the following recommendations for the cable
bushings:
