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.

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.

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:

7. Push the seal with the contact socket of the gland and (item 2+3)
flush into the lower part (item 5).
8. Screw the domed cap nut (item 1) onto the lower part (item 5).
Grounding the Barometer Housing
In case you need to ground the barometer housing, the grounding
connector is found inside the housing. Make sure that different
groundings are made to the same potential. Otherwise harmful ground
currents may be generated.
If a galvanic isolation of the power supply line from the output signals
is needed, the barometer can be ordered with an optional output
isolation module. This module prevents harmful grounding loops.
Alternate Wiring Systems
There are optional ways to connect the barometer: using basic wiring,
the D-9 connector, or the M-12 connector.
The wiring system is selected when ordering the device. If a connector
is needed for wiring, it is set at the factory.
- When using basic wiring, see section Signal and Power Supply
Wiring on page 32.
- When using 8-pin connector, see section M-12 (8-Pin) Connector
on page 34.
- When using D-9 connector, see section D-9 Connector on page 35.

Chapter 3 _______________________________________________________________ Installation
7. If you are connecting several barometers to the same RS-485 bus,
make sure that switches 1 and 2 are OFF and terminate the bus with
separate terminators at both ends. This allows removing any
barometer without blocking the bus operation.
8. Use the bus type (4-wire/2-wire) to select the selection switch 3.
9. In 4-wire mode RS-485 master sends data to the PTB330
barometer through terminals RxA and RxB and receives data from
PTB330 barometer through terminals TxA and TxB.

MI70 Link Interface Software for Data Handling
Recorded data can be transferred to a PC by using MI70 Link Interface
Software. You can examine the recorded data easily in Windows
environment and transfer it further to a spreadsheet program (such as
Microsoft Excel) or virtually to any Windows program in numeric or
graphical format. the MI70 link program also allows you to monitor
barometer readings directly with a PC (real-time window function).
The MI70 Link Interface Software is available from Vaisala.
1. Connect the connection cable between the serial port of your PC
and the Service Port of the barometer.
2. Check that the barometer is powered up and start using the MI70
Link program.
Use a MI70 Link version 1.10, or a newer one, to be able to utilize all
the functions of the barometer.
Serial Line Communication
Connect the serial interface by using either the user port or the service
port.
For permanent interfacing to host system, use the user port. You can
change the serial settings and operate in RUN, STOP and POLL modes.
For temporary RS-232 connections use the service port. Service port is
always available with fixed serial settings and it starts in the STOP
mode after power-up always.

Operation of Relays
Quantity For Relay Output
A relay monitors the quantity chosen for the relay output. Any of the
quantities available can be chosen.
Measurement-Based Relay Output Modes
Relay Setpoints
When the measured value is in between the "above" and "below"
values, the relay is passive. When choosing lower value as "above"
value and higher value as "below" value, the relay is passive when the
measured value is not between the setpoints. You can also set only one
setpoint. See Figure 41 on page 90 below for illustrative examples of the
different measurement-based relay output modes.
VAISALA_______________________________________________________________________ 89
User's Guide ______________________________________________________________________
NOTE
0610-076
Figure 41 Relay Output Modes
Mode 4 is usually used if an alarm needs to be triggered when the
measured value exceeds a safe range. The relay is active when
measurement is in range, and is released if the value goes out of range
or the measurement fails.
If the measurement of the selected quantity fails or the barometer loses
its power, the relay is released.
Hysteresis
The hysteresis function prevents the relay switching back and forth
when the measured value is near to the setpoint values.The relay is
activated when the measured value passes the exact value of the
setpoint. When returning to and passing through the setpoint again, the
relay is not released before the value reaches the setpoint increased/
decreased by the hysteresis value, see Figure 41 on page 90. The
hysteresis should be smaller than the difference of the setpoints.
90 __________________________________________________________________ M210855EN-C
Chapter 4 ________________________________________________________________ Operation
NOTE
If both setpoints are specified and the "above" setpoint is lower than
the "below" setpoint, the hysteresis works in the opposite direction,
that is, the relay is released when the measured value passes the exact
value of the setpoint.
Relay Indicating Barometer Error Status
You can set a relay to follow the operation status of the device. By
selecting FAULT/ONLINE STATUS for output quantity a relay
changes state on the basis of the operation status as follows:
FAULT STATUS
Normal operation: relay active (C and NO outputs are closed)
Not measuring state (error state or power off): relay released (C and NC
outputs are closed).
ONLINE STATUS
Live measurement (data available): relay active (C and NO outputs are
closed)
No live data (for example: error state or adjustment mode): relay
released (C and NC outputs are closed).
See Figure 42 on page 92 below for illustrative examples of the
FAULT/ONLINE STATUS relay output modes.
VAISALA_______________________________________________________________________ 91
User's Guide ______________________________________________________________________
NOTE
0610-077
Figure 42 FAULT/ONLINE STATUS Relay Output Modes
FAULT/ONLINE STATUS relays are usually used in conjunction with
an analog output to obtain validity information for the output value.
If a barometer loses its power, all status-based relays are released
similarly to the case of an instrument failure.
Enabling/Disabling Relays
You can deactivate the relay outputs for example for service purposes
of your system.

Setting Relay Outputs
RSEL
NOTE
When only one relay module is installed, its relays are called "relay 1"
and "relay 2".
Use the serial line to select the quantity, setpoints and hysteresis or
enable/disable the relay outputs. The factory setting is that all the relays
are disabled. Enter the RSEL command.
RSEL [q1 q2...]
where
q1 = quantity for the relay 1 or Fault/Online
q2 = quantity for the relay 2 or Fault/Online
and so on
Use the quantity abbreviations presented in Table 1 on page 18 above.
Example of window limit switch:
Selecting relay 1 to follow pressure measurement and relay 2 to follow
measurement of pressure from barometer module 1. Two relay setpoints
are set for both relays.

Enter the command RTEST without parameters to stop testing.
Operation of RS-485 Module
RS-485 interface enables communication between RS-485 network and
the barometer. The RS-485 interface is isolated and offers a maximum
communications rate of 115 200 bits/s. (For maximum bus length of 1
km, use bit rate 19200 b/s or less.)
When selecting an RS-232-RS-485 converters for the network, avoid
self powered converters as they don't necessarily support the needed
power consumption.
NOTE
User port on the barometer main board cannot be used and connected
when RS-485 module is connected. Service port is operating normally.
Networking Commands
Set the RS-422/485 interface by using the following commands.
RS-485 configuration commands SERI, ECHO, SMODE, ADDR
INTV can be entered by using either the service port or the RS-422/485
port. Also the optional display/keypad can be used, see section User
Port Serial Settings on page 81.
SDELAY
With the SDELAY command you can set delay (response time) for the
user port (RS232 or RS485), or view currently set delay value. Value
corresponds to tens of milliseconds (for example, 5 = 0.050s minimum
answer delay). The value can be set between 0...254. Example:
>sdelay
Serial delay : 0 ? 10
>sdelay
Serial delay : 10 ?
VAISALA_______________________________________________________________________ 95
User's Guide ______________________________________________________________________
SERI
Use the SERI command to input RS-485 bus settings.
SERI [b p d s]
where
b = bit rate (300, 600, 1200, 2400, 4800, 9600, 19200, 38400,
57600, 115200)
p = parity (n = none, e = even, o = odd)
d = data bits (7 or 8)
s = stop bits (1 or 2)
ECHO
Use the ECHO command to enable/disable echo of characters received
over the serial line.
ECHO [x]
where
x = ON/OFF (default = OFF)
Echo function shall be always disabled (OFF) when using the 2-wire
connection. When using the 4-wire connection you can disable/enable
the echo setting.
SMODE
Use the SMODE command to set the default serial interface mode.
SMODE [xxxx]
where
xxxx = STOP, RUN or POLL
In STOP mode: measurements output only by the command SEND,
all commands can be used.
96 __________________________________________________________________ M210855EN-C
Chapter 4 ________________________________________________________________ Operation
where
In RUN mode: outputting automatically, only the command S or
pressing the ESC key can be used to stop.
In POLL mode: measurements output only with command SEND
[addr]
When several barometers are connected to the same line, each
barometer must be entered an own address in the initial configuration,
and POLL mode must be used.
INTV
Use the INTV command to set the RUN mode output interval.
INTV [n xxx]
where
n = 0...255
xxx = S, MIN or H
Sets the RUN mode output interval. The time interval is used only when
the RUN mode is active. For example, the output interval is set to 10
minutes.
>INTV 10 min
Output interval: 10 min
>
Setting RUN output interval to zero enables the fastest possible output
rate.
ADDR
Addresses are required only for POLL mode (see serial line command
SMODE on page 82). Use the ADDR command to input the RS-485
barometer address.
VAISALA_______________________________________________________________________ 97
User's Guide ______________________________________________________________________
ADDR [aa]
where
aa = address (0 ... 255) (default = 0)
Example: the barometer is configured to address 99.
>ADDR
Address : 2 ? 99
>
SEND
Use the SEND command to output the reading once in POLL mode:
SEND [aa]
where
aa = address of the barometer
SCOM
Use the SCOM command to show or set an alias for the SEND
command. The given alias cannot be a command already in use.
Example:
>scom meas
Send command : meas
>send
pressure = 1013.02 hPa
>measpressure = 1013.02 hPa
>
OPEN
When all barometers on the RS-485 bus are in POLL mode the OPEN
command sets one barometer temporarily to STOP mode so that other
commands can be entered.
