Pressure Sensors 



Pressure sensors are used to convert plant 

 pressure to an electrical signal for further 



transmission to the Engine Room Console. Two 

 of the main types of sensors are the pressure- to- 

 current transmitter and the pressure switch 

 types. 



The pressure-to- current transmitter (fig.

 current proportional to the applied pressure. 

 This current can then be applied to a meter for
