3.2.2  Use With Other Controllers 

The transmitter can also be operated with other controllers. 
Especially the fieldbus version ITR 90 P (Profibus) is usually operated as part of a 
network, controlled by a master or bus controller. In such cases, the control system 
has to be operated with the appropriate software and interface protocol (

 [3]). 

 

 

3.2.2.1  Making an Individual Sensor Cable 

  For reasons of compatibility, the expression "sensor cable" is used for all 

ITR 90 versions in this document, although the pressure reading of the 
ITR 90 P transmitter with fieldbus interface is normally transmitted via 
Profibus. 
The sensor cable is required for supplying all ITR 90 types with power. 
In connection with the ITR 90 P transmitter with fieldbus interface it also 
permits access to the relay contacts of the switching functions (

 20). 

 
 

 

Cable type 

The application and length of the sensor cable have to be considered when deter-
mining the number and cross sections of the conductors (

→

 

 8). 

 

 

Procedure 

  Open the cable connector (D-Sub, 15-pin, female). 

  Prepare the cable and solder/crimp it to the connector as indicated in the 

diagram of the transmitter used:
