Sample applications
Controlling a positioning cylinder in the paper and printing
industry
The electric signal (i) of a controller received from the PLC isconverted into a pneumatic signal (p) by the i/p converter.
The pressure signal is used to position a cylinder which, inturn, moves a roller that keeps the paper under a certain tension.

ipSupply air

Type 6111

Valve control
Valves with small pneumatic actuators can be controlled
directly by an i/p converter. The i/p converter receives theelectric signal of a controller received from the PLC.

TROVIS 6493

The i/p converter can also control a pneumatic positioner.

SupplyairField or industrial units can be mounted directly to a valve(attachment to rod-type yoke or according to NAMUR).

ip
Type 6116

Pressure control
The p/i converter measures the pressure in the pipeline andconverts it into an electric signal. The positioner uses the electric signal to calculate the control signal to open or close thepneumatic control valve.

Filling of liquids in the beverage industry and breweries
An electric signal is converted into a pneumatic signal by thei/p converter. The pneumatic signal is used to position thecylinders which insert filling tubes into bottles, depending on
the liquid level, to fill them with beverages or detergents.

Supply airpi

Booster control
Boosters are used to amplify the flow rate of compressed air.
In place of a handwheel, they can also be controlled by ani/p converter, which receives an electric signal of a controller
from the PLC.
Type 6111

SupplyairpApplying adhesive or glue
Glue or adhesive is to be applied on different bases.

Type 6126

Depending on the speed of the conveyor belt, varying quantities must be applied. The i/p converter receives an electricsignal, which changes with the belt speed and converts it intoa pressure signal. The pressure causes the ball of a dispenser
to adapt the outlet to the required amount of glue or adhesive.
This ensures uniform application.

Sample applications
Flow temperature control of a heat exchanger
The TROVIS 6493 or TROVIS 6495-2 Controller logs the flow
temperature T in the secondary circuit and positions the valve
in the primary circuit to regulate the flow temperature.

TROVIS 6493
TROVIS 6495-2

TFlow temperature control of a heat exchanger based on theoutdoor temperature
The TROVIS 6493 or TROVIS 6495-2 Controller logs the flowtemperature T1 in the secondary circuit and positions the valve
in the primary circuit to regulate the flow temperature. The set
point for the flow temperature is determined according to acharacteristic based on the outdoor temperature T2.

Pressure control
The TROVIS 6493 or TROVIS 6495-2 Controller logs the pressure downstream of the valve received from a pressure transmitter and positions the valve accordingly to regulate the pressure.

Sample applications
Control of the mixing ratio of two liquids
The TROVIS 6495-2 Industrial Controller logs the flow rates F1
and F2 from two flow transmitters. It positions the control valve
for the medium to be added to achieve the required mixing
ratio F1/F2 (ratio control).

Control of the mixing ratio of two liquids and control of themain flow rate
The TROVIS 6495-2 Industrial Controller logs the flow rates F1and F2 from two flow transmitters. The internal controller [1]positions the control valve for the medium to be added toachieve the required mixing ratio F1/F2 (ratio control). Theinternal controller [2] positions the control valve for the othermedium to achieve the flow rate F2.

Temperature cascade control
The TROVIS 6495-2 Industrial Controller regulates the producttemperature in a vessel and limits the flow temperature of theheat exchanger with the cascade control mode. The
temperature in the vessel is generated by steam, which isproduced by a heat exchanger and a fluid circulation system.
The master controller [2] receives the product temperature T2
in the vessel and provides its output variable as the set point
for the slave controller [1]. The slave controller [1] logs theflow temperature T1 of the heat exchanger and positions thecontrol valve to regulate the flow temperature and the producttemperature. To prevent the product from overheating, the set
point for flow temperature is limited to a maximum
temperature. Additionally, the pressure and temperaturefluctuations in the steam network can be eliminated faster by
the slave controller before they cause a noticeable
temperature change in the boiler due to the shorter delays inthe heat exchanger circuit. This improves the control accuracy.
The steam heat exchanger can alternatively be controlledusing a steam pressure control in the condensate circuit. In thiscase, the control valve is installed in the condensate pipe
instead of the steam pipe.

Sample applications
Flow rate control with pressure limitation
The TROVIS 6495-2 Industrial Controller controls the flow ratewith the override control mode to ensure that the pressure
does not exceed a certain limit. In this case, control signals of
two internal controllers influence the control valve by selectionof a minimum value. The main controller [1] regulates the flowrate F and the override controller [2] limits the pressure P to amaximum pressure. The controller with the smallest output
value is used to position the valve. If the controller [1] isactively positioning the control valve, the control signal ofcontroller [2] is greater than that of controller [1] by theadjustable limiting band at the maximum. This limitation
causes controller [2] to take over control more quickly when
the pressure exceeds a certain limit.

influence the control valve by selection of a minimum value.
The main controller [1] regulates the flow temperature T1 andthe override controller [2] limits the return flow temperature T2
to a maximum temperature. The controller with the smallest

Temperature control with two control valves for heating andcooling (split-range control)
The TROVIS 6495-2 Industrial Controller logs the coolant temperature T of a machine and positions one control valve forheating and one control valve for cooling over two analog
outputs to regulate the coolant temperature. In split-range operation, the working range is assigned to two analog outputs
to allow the cooling valve to close first and then the heatingvalve to open as the control signal rises.

Explosion protection
Some of the SAMSON electropneumatic converters are suitable for use in hazardous areas as they are frequently used in
the chemical and petrochemical industry.

Important factors of the explosion protection relevant for suchapplications are listed in the following. For details, please refer to the standards mentioned.

Zone classification
Hazardous areas are grouped into zones to indicate the risk of explosion. Each zone prescribes particular measures which ensure
explosion protection.
Zone

Identifier

Example0Dangerous, potentially explosive atmospheres occur permanently or for a long time.

Inside of reaction tanks containing flammable gases

1

Dangerous, potentially explosive atmospheres occur occasionally.

In the proximity of Zone 0, immediate area around packing
that are not sufficiently sealed.

2Dangerous, potentially explosive atmospheres occur rarely orfor a short time (less than two hours).

Areas surrounding the Zones 0 and 1

Type of protection
The type of protection describes the measures to be taken to prevent electrical appliances from igniting explosive atmospheres.
Type of protection

Basic principle

Standard or regulationd Flameproof enclosure

Parts which can ignite an explosive atmosphere are placed in
an enclosure which can withstand the pressure caused by an
explosion inside the enclosure and prevents the transmission of
the explosion to the surrounding explosive atmosphere.
Flameproof enclosures are suitable for Zones 0, 1 and 2.

DIN EN 60079-1

An electrical device is intrinsically safe when all circuits are intrinsically safe.
A circuit is intrinsically safe when it does not produce sparksor thermal effects whose energy suffices to ignite an explosiveatmosphere.

Category ia

Devices of this category are suitable for Zones 0, 1 and 2.
Zone 0 must be certified separately.

Category ib

Devices of this category are suitable for Zones 1 and 2.

Temperature classes
The temperature classes group electrical appliances according to their max. permissible surface temperature. It must be smaller
than the ignition temperature of the explosive material.

13UNEx24

Safety barriers are passive networks which separate intrinsically safe and non-intrinsically safe circuits without isolatingthem electrically. The output circuits of the safety barriers meetthe requirements of the intrinsic safety “ia” and “ib”.
Safety barriers are always installed outside the hazardous
area.
