Safety instructions and measures
1 Safety instructions and measures
Intended use
The Type6134 p/i Converter converts a pneumatic signal into a standardized electric signal.
It is especially used as an intermediate element between pneumatic and electric control and
measuring equipment.
The pneumatic input signal from 0.2 to 1bar is converted into an electric DC signal from 4
to 20mA.
The device is designed to operate under exactly dened conditions (e.g. input signal, pres-
sure). Therefore, operators must ensure that the device is only used in operating conditions
that meet the specications used for sizing the device at the ordering stage. In case operators
intend to use the device in other applications or conditions than specied, contact SAMSON.
SAMSON does not assume any liability for damage resulting from the failure to use the de-
vice for its intended purpose or for damage caused by external forces or any other external
factors.
ÎRefer to the technical data and nameplate for limits and elds of application as well as
possible uses.
Reasonably foreseeable misuse
The device is not suitable for the following applications:
−Use outside the limits dened by the technical data
Furthermore, the following activities do not comply with the intended use:
−Use of non-original spare parts
−Performing service and repair work not described
Qualications of operating personnel
The device must be mounted, started up, serviced and repaired by fully trained and qualied
personnel only; the accepted industry codes and practices must be observed. According to
these mounting and operating instructions, trained personnel refers to individuals who are
able to judge the work they are assigned to and recognize possible hazards due to their spe-
cialized training, their knowledge and experience as well as their knowledge of the applica-
ble standards.
Explosion-protected versions of this device must be operated only by personnel who has un-
dergone special training or instructions or who is authorized to work on explosion-protected
devices in hazardous areas.

1.2 Notes on possible personal injury
WARNING
!
Risk of personal injury through incorrect operation, use or installation as a result of
information on the device being illegible.
Over time, markings, labels and nameplates on the device may become covered with
dirt or become illegible in some other way. As a result, hazards may go unnoticed and
the necessary instructions not followed. There is a risk of personal injury.
ÎKeep all relevant markings and inscriptions on the device in a constantly legible
state.
ÎContact our after-sales service to renew damaged, missing or incorrect nameplates
or labels.

Safety instructions and measures
WARNING
!
Risk of personal injury due to exhaust air being vented.
While in operation, the device vents exhaust air over the vent plug.
ÎLocate the vent plug on the opposite side to the work position of operating person-
nel.
1.3 Notes on possible property damage
NOTICE
!
Risk of device damage due to failure to meet air quality requirements.
Insufcient air quality can damage components and seals inside the device.
ÎOnly use supply air that is dry and free of oil and dust.
ÎObserve the air quality according to ISO8573-1:2001.
ÎBlow through all air pipes and hoses thoroughly before connecting them.
Risk of device damage due to the maximum supply pressure being exceeded.
The maximum supply pressure for the device is restricted. A supply pressure higher
than the maximum permissible supply pressure may damage the device.
ÎRefer to the technical data for the maximum permissible supply pressure.
ÎMake sure that the air supply does not exceed the maximum permissible supply
pressure.

1.4 Special instructions concerning explosion protection
Servicing explosion-protected devices
ÎObserve the following for servicing equipment in a section relevant for explosion
protection:
It must not be put back into operation until a qualied inspector has assessed the
equipment according to explosion protection requirements, has issued an inspec-
tion certicate or given the device a mark of conformity. Inspection by a qualied
inspector is not required if the manufacturer performed a routine test on the device
before putting it back into operation. Document the passing of the routine test by
attaching a mark of conformity to the device.
Replace explosion-protected components only with original, routine-tested compo-
nents by the manufacturer.
Devices that have already been used outside hazardous areas and are intended
for future use inside hazardous areas must comply with the safety requirements
placed on serviced devices. They must be subjected to testing according to the
specications in EN60079-19.
EN60079-19 applies to servicing explosion-protected devices.

3 Design and principle of oper-
ation
The Type6134 p/i Converter converts a
pneumatic signal into a standardized electric
signal. It is especially used as an intermedi-
ate element between pneumatic and electric
control and measuring equipment.
The pneumatic input signal from 0.2 to 1bar
is converted into an electric DC signal from
4 to 20mA.
Principle of operation (see Fig.3-2)
A capacitive ceramic pressure sensor (1) is
used to convert the pressure p of the pneu-
matic input signal into an electric DC volt-
age signal. The DC voltage signal which is
proportional to the pressure is amplied to a
dened level in the measuring amplier (3).
The lower range value and span can be ad-
justed using potentiometers on the front pan-
el. The constant DC voltage source (2) is
used to supply the DC voltage at a constant
level. Control equipment can be connected to
the output circuit.
Output circuit
In two-wire systems, the maximum permissi-
ble load impedance at the output is:
UB= US– UARB= UB/20mA
UBMaximum permissible load impedance
RBMaximum permissible load
USSupply voltage of the two-wire circuit
UA12V, input voltage requirement (mini-

Maximum permissible load impedance at the
output: UB=20V –12V=8V
Load: RB= UB/20mA = 400Ω
