1 General Safety Instructions
• Select the appropriate pressure transmitter with regard to scale range,
performance and specific measurement conditions prior to installing and
Warnin
starting the instrument.
• Observe the relevant national regulations (e.g.: EN 50178, NEC, CEC)
and observe the applicable standards and directives for special
applications (e.g. with dangerous media such as oxygen, acetylene,
flammable gases or liquids and toxic gases or liquids and with
refrigeration plants or compressors).
If you do not observe the appropriate regulations, serious injuries
and/or damage can occur!
• Open pressure connections only after the system is without
pressure!
• Please make sure that the pressure transmitter is only used within the
overload threshold limit at all times!
• Observe the ambient and working conditions outlined in chapter 6
"Technical Data"
• Ensure that the pressure transmitter is only operated in accordance with
the provisions, i.e. as described in the following instructions.
• Do not interfere with or change the pressure transmitter in any other way
than described in these operating instructions...
• Remove the pressure transmitter from service and mark it to prevent it
from being used again accidentally, if it becomes damaged or unsafe for
operation..
• Take precautions with regard to remaining media in removed
pressure transmitter. Remaining media in the prsesure port may
be hazardous or toxic!
• Have repairs performed by the manufacturer only.
• Consider the details given in the EC-type examination certificate as well
as the respective specifications for explosion hazard use of the country
concerned (e.g.: IEC 60079, NEC, CEC). If you do not observe these
stipulations, serious injuries and/or damage can occur.
Other important safety guidelines can be found in the different sections of
this instruction manual.

Special Intrinsic Safety Instructions
2 Special Intrinsic Safety Instructions
2.1 Protection of diaphragm
As soon as the diaphragm of an instrument gets damaged, absolutely no intrinsic
safety can be guaranteed any longer! Thus the diaphragm must not come in contact with abrasive substances! The diaphragm must be protected against pressure
Warning
peaks and must not be touched by tools! Information about material consistency
against corrosion and diffusion can be found in our WIKA Handbook, 'Pressure and
Temperature Measurement' (German: ISBN 3-9804074-0-3, English: ISBN 39804074-1-1).
2.2 Special wiring advice
The housing must always be connected to earth to protect the instrument against
electromagnetic fields and electrostatic charges.
Warning
The cables and wires must not be damaged.
Cables for applications in Zone 1 and 2 or Zone 21 and 22 must be checked with
a test voltage between conductor/earth, conductor/screen, screen/earth of more
than 500 V (AC).
Flying leads with fine wires must be covered by an end splice (cable preparation).
Both the internal capacity and inductivity must be considered.
Conductive screens may only be connected to earth one-sided and outside the
hazardous area.
2.3 Connection to Zone 0
(In general Zone 0 is given when the instrument is surrounded by a mixture of
explosive gases more than 1.000 hours per year = continuous hazard. The trans-
Warning
mitter may only be operated under Zone 0 conditions, as long as an atmospherical
pressure of 0.8 to 1.1 bar is guaranteed).
The circuits must be of type Ex ia.
The ingress protection must comply to IP 67 according to IEC 529.
2.4 Special precaution for connection to Zone 0 and or Zone 20
Make absolutely sure to follow the advice given in the IEC publication 60 529 for
connection to Zone 0 and/or Zone 20 for IP 67 pressure connections!
Warning
Warning
Installation in non-metallic vessels:
All metallic parts reaching into Zone 0 and/or Zone 20 must be grounded.
The intrinsically safe circuit must be decoupled from the regular circuit.
If the mounting position is less than 1m away from the transition into Zone 0 and/or
Zone 20 an overvoltage protection must be integrated. This can either be done
within the transmitter (option: overvoltage protection), or outside the transmitter by
the customer himself.

Warning
Warning
Observe the maximum temperature value (of the temperature range defined under
item 15.3. in the EC type test certificate at the hexagon of the process connection.
Protect the pressure transmitter against touching or affix a warning notice.
Insulate heat sources thermally from the pressure transmitter (e.g. pipes or tanks).
2.6 Special instructions for dust explosion protection
Ensure that under hazardous dust environments the pressure transmitter is mounted in a shielded section and protect it against shocks.
Warning
Warning
When installing the pressure transmitter or the cable gland into areas which require
category 1D equipment, ensure that ingress protection IP 6X according to IEC 60
529 is guaranteed.
Observe the EN 50281-1-2 in relation to e.g. dust deposits and temperature.
The permissible ambient temperatures as well as the maximum surface temperatures are to be taken from the EC type test certificate.

Universal IS Pressure Transmitter UniTrans
Product Description
5 Product Description
The intrinsically safe pressure transmitter UniTrans can be used in level control
applications as well as for pressure measurement applications in process industry.
A variety of process connections, measurement ranges, main boards and display
options result in a product for a wide range of applications.
5.1 Construction
The UniTrans consists of a pressure sensor, a control interface unit and a housing
cover with optional display. Due to this modular design, different transmitter versions
can be mounted (see “Model Key” on page 151).
Direct Mounted
Processing Unit Housing
5.1.1 Pressure Transducer
The pressure transducer has a piezo-resistive or thinfilm measurement cell depending on the pressure range. The sensors are temperature compensated, and have a
hermetically welded membrane which is "helium" leak-tested. The pressure transducers do not have internal sealing elements.
Pressure transducers further distinguish themselves from one another based on their
pressure ranges and the different materials of wetted parts. Different process connections can be selected to serve a wide range of applications.
Never exceed the overpressure limit of the respective pressure transducer.

Product Description
5.1.2 Processing Unit
The processing unit, which is integrated in the housing contains the terminal compartment and the keypad used for programming the transmitter. The four keys must be
activated (unlocked) before use. During normal operation the keypad is locked to protect data and functions previously entered. The keypad is automatically locked when
no key is hit for 10 minutes. The processing unit converts the digitalized signal from
the measuring unit into a standard 4...20 mA current signal.
Processing Unit
5.1.3 Display Unit
CALIBRATION
RANGE
The measured-value indicator has four digits (in a 7-segment display) + symbols. Below it, is line 1 (16-segment display) used to display error codes and the signal’s unit
of measure. The unit of measure can be selected by the operator. Measurements
over 9999 can not be correctly displayed. Please note this when choosing the unit
(e.g. 9999 Pascal = 0,09999 bar). Additional information is displayed in lines 2 and 3
(16-segment display). The operator can enter commands in the programming mode
on the display unit by means of menu guided, clear-text prompts.

Universal IS Pressure Transmitter UniTrans
Product Description
Transmitters with displays offer a larger number of programming and processing options. These options include alarm status, damping, signal inversion, tank linearization and diagnostic messages.
Display units can be easily upgraded (see chapter 7.2).
5.2 Function
The pressure transducer converts the existing pressure into an electrical signal. Microelectronics further process the input signal and produce a proportional 4-20 mA
standard signal.
The display-version allows programming (parameterization) and the display of extended functions such as inversion, damping, alarm status and linearization.
5.2.1 Functions of Transmitters without Displays
• Calibration of zero and span under pressure (see 8.3)
• Calibration of zero and span without pressure (dry adjustment) (see 8.4)
• Setting the dampening / integration of the output signal 0-40 s (see 8.5)
• Reset to manufacturer’s default values (see 8.6)
• Mounting correction of the sensor (beginning with software version 1.05, see 8.4.3)
5.2.2 Functions of Transmitters with Displays
• Settable units of measurement (mbar, bar, psi, mA, %, m, mm WS) (see 9.5.1)
• Volume-related unit of measuring value can be set (l, kg, t, m
• Temperature and Min/Max values shown in display (see 9.5.1)
• Nominal pressure range of the sensor shown in display (see 9.5.1)
• Zero and span calibration (with/without pressure) (see 9.5.2)
• Setting of damping / integration of output signal 0-40 s (see 9.5.3)
• Inversion of the output current signal (see 9.5.3)
• Setting the output current value in case of alarm (3.6 mA or 21 mA) (see 9.5.3)
• Setting the limits of the output signal (see 9.5.3)
• Offset of the output signal (see 9.5.3)
• Mounting correction of the sensor (beginning with software version 1.05, see 8.4.3)
