Design and principle of operation

Design and principle of oper-

ation

The option module with a 4 to 20 mA 
current loop can be added to the Media 5 
Differential Pressure and Flow Meter. It 
allows the measured value to be 

electronically processed for measuring and 

control tasks. The loop current is proportional 

to the pressure and is measured from the 

pointer position of the Media 5 device 
without any contact or interference. 
The option module is installed in the Media 5 
device. When ordered together with the 
Media 5 device, it is installed already in the 
delivered state. In all other cases, it can be 
retrofi tted by the customer.

Notes on explosion protection

The option module is available in two differ-
ent versions:
The following applies to the version 

with 

explosion protection

 (100049064):

1.  When working on explosion-protected 

versions of the option module, personnel 
must undergo special training or instruc-
tions or be authorized to work on explo-
sion-protected devices in hazardous ar-
eas.

2. 

The current loop must be supplied only 

by a supply unit which has a equivalent 
or higher explosion protection approval. 
Its electrical connection data must be 
lower or identical to those in the explo-
sion protection certifi cate of the 
Type 5005-3 device.

3.  Permission to operate the option module 

in hazardous areas becomes void after 
the following events:

One of the permissible electrical 

values listed in the explosion-

protection certifi cate is exceeded, 

even when only briefl y. 

To continue 

operation of the option module in 

hazardous areas in such cases, 
SAMSON or a person with the 
corresponding qualifi cations must 
provide eviden that all safety/
protection features within the device 
or module are fully effective.

The specifi cations described in 2. for 

the supply unit are not observed. 

Operation of the option module must 

not be continued in such cases. The 
option module must be replaced.
