2 General information
2.1
Scope of application
General information
The JUMO dTRANS p20 pressure transmitter measures the pressure of non-corrosive and
corrosive gases, vapors and liquids. The output signal is an impressed DC current
(4 to 20 mA) which is proportional to the input pressure.
Use in "Ex areas"
The pressure transmitter in the Ex ia version is approved for use in "Ex areas" if the
nameplate on the device so indicates.
CAUTION!
The diaphragms of the process connection must not be damaged! Do not insert any
objects into the hole of the pressure connections!

2.2
Scope of delivery
Operating Manual B 403025.0
This operating manual describe the assembly, the installation and the operation of the
JUMO dTRANS p20 pressure transmitter.
Calibration certificate
The pressure transmitter comes with a calibration certificate and a SETUP printout. These
documents contain information about the measured parameters or set parameters for the
relevant pressure transmitter.
If the calibration certificate is lost, or if you need another copy, it can be ordered from JUMO.
Please indicate the F number of the pressure transmitter (manufacturing number, see the
nameplate).
Your supplier's address can be found on the back of the manual.
Setup program
The setup program is available as an accessory, part no. 00537577.
The setup program provides a convenient way to check and adjust all parameters of the
pressure transmitter. It also includes additional functions such as:
• Recording of measurements
• Graphical presentation of temperature and pressure
• Extensive diagnostic messages
• Display of complete order code and device configuration (for reordering).
The setup program accesses the pressure transmitter via
• the JUMO interface (standard)
• or HART® interface (optional)
CAUTION!
The JUMO interface must not be used for devices with ATEX Ex ia explosion protection!
These devices must only be operated with the rotary knob or via the HART® interface!
PC interface cable
Available as an accessory: PC interface cable including USB/TTL converter and two adapters
(USB connecting cable), part no. 00456352.
The PC interface cable can be used to connect the pressure transmitter to the USB interface
of a PC via the JUMO interface.
8
2 General information
HART® modem
Available as an accessory: HART® modem for USB, part no. 00443447.
The HART® modem can be used to connect the pressure transmitter with the USB®
interface of a PC via the HART® interface.
Supply isolator
Available as an accessory: Supply isolator for Ex applications, HART®-enabled,
part no. 00577948.
Pressure transmitter with ATEX Ex ia explosion must be connected for use in Ex areas by
means of a supply isolator!
Remote seals
Available as an accessory: See data sheets 409770 to 409786.
Remote seals are used for adaptation to special applications, when conventional pressure
connections cannot be used.
CAUTION!
Remote seals are installed in the factory and must not be separated from the pressure
transmitter!

NOTE!
The installation location should be easily accessible, if possible in the vicinity of the
measuring point and low in vibration. The permissible ambient temperature must be
maintained (not any possible heat radiation).
The JUMO dTRANS p20 pressure transmitter can be installed above or under the pressure
tapping point.

Installation instructions
DANGER!
The electrical connection must only be performed by qualified personnel!
Ground the device!
If contact with live parts is possible when working on the device, it must be completely disconnected from the electrical supply.
Electromagnetic compatibility meets the requirements of EN 61326.
The transmitter is suitable for use in SELV or PELV current circuits according to protection
rating 3.
For connection to devices with Ex approval see "Electrical connection in Ex areas", page 41!
Apart from faulty installation, incorrect settings on the device may also affect the proper functioning of the subsequent process or lead to damage. You should therefore always provide
safety equipment that is independent of the device and it should only be possible for qualified personnel to make settings.

Electrical connection in Ex areas
General information
Applicable requirements must be followed for the electrical connection, especially in a
potentially explosive atmosphere:
• Regulation concerning electrical systems in areas with an explosion hazard (Elex V)
• Determination for project planning, selecting and setting up electrical systems in areas
with an explosion hazard (IEC 60079-14)
• EC-type examination certificate
NOTE!
Only certified measuring devices may be used in intrinsically safe circuits!
NOTE!
The intrinsically safe circuit must be limited to overvoltage category II as defined in IEC
60664-1 and the power of the circuit follows only out of a certified and intrinsically safe
power source with a safety protection "ia".
NOTE!
Equipment for potentially explosive areas which contain hybrid mixtures has to be especially checked for this use. Hybrid mixtures are potentially explosive mixtures out of combustible gases, vapors, or mists with combustible dust. The operator bears the res-ponsibility
of checking if the equipment is suitable for such uses.
41
6 Installation
DANGER!
The JUMO interface must not be used for devices with ATEX Ex ia explosion protection!
These devices must only be operated with the rotary knob or via the HART® interface!
The voltage supply must be intrinsically safe and must not exceed the maximum values of
the transmitter:
Ui: DC 28 V
Ii: 115 mA
Pi: 750 mW
NOTE!
Connecting the HART® communicator or HART® modem is optional.
To ensure error-free communication, a minimum burden must be present on the signal
circuit; see preceding pages.
When supply isolators are used, the burden is usually already integrated.

The device can be
• operated with the rotary knob (1)
• or with the optional setup program.
NOTE!
Instead of operation by keyboard, all actual values and parameters can be displayed or set
very easily with the setup program. In addition, the setup program offers a series of useful
additional functions such as:
• Recording of measurements
• Graphical presentation of temperature and pressure
• Extensive diagnostic messages
• Display of complete order code and device configuration (can be printed out, for
example for project documents or reordering).
The setup program can optionally access the device through the following interfaces:
• JUMO setup interface.
The PC interface cable with USB/TTL converter (USB connecting cable) is required to
connect the PC with the device, part no. 00456352.
• HART® interface.
A HART® modem is required to connect the PC with the device,
