Hi,

I am building a system where I require to detect if the pressure inside pneumatic pipe has gone below 4 bar or above 6 bar pressure. If the pressure goes out of this limit I should be able to cut off the instruments from this pneumatic line automatically. As I am new to this, please suggest me which kind of sensors should i use for this kind of application.

Thanks In Advance.

 

Google "industrial pressure switch".

You'll need a switch assembly (sensor and switches) with two independent switches, each with its own setpoint adjustment.

One switch is set to trip 'low/falling' at 4 bar, the other to trip high/rising' at 6 bar.

 

Hi Tapas,

For your application, pressure switch will suit your needs. Please check following document from Schneider electric that contain selecting guide of their pressure switch:
